Review & Installation Video

Hey everybody, I'm Justin with AmericanMuscle.com. Welcome to the breakdown and sound clips of the Pypes Off-Road H-Pipe, available for your 2005 to 2010 Mustang GT. Swapping out your factory mid-pipe in favor of an aftermarket option is not only a great way to pick up some power, but can also totally transform the way your Mustang sounds. Now when deciding on a mid-pipe for your own ride, you do have a couple of different options. For instance, we can go with an off-road X-pipe or H-pipe like we have here, which is going to be devoid of any catalytic converters. On the other hand you can go with a catted mid-pipe, which will incorporate some kind of small, high-flow cat into the design. In addition to that, you will have to choose whether you want an H-pipe or an X-pipe. Traditionally you can expect a slightly raspier exhaust note when going with an X-pipe, and it's going to produce some slightly higher top-end horsepower gains. On the other hand, the H-pipe, like I do have with me here today, is going to give you that lower muscle car rumble, it's going to help reduce some of the rasp, and it should produce some slightly lower torque gains. Now, ultimately, guys, it's up to you to decide which mid-pipe you want to go with and what style you're looking for, for your own ride. Getting into some of the details here with this H-pipe from Pypes, you will notice 2 1/2-inch mandrel bent stainless steel tubing for the build, in addition to all your O2 bungs, which have already been pre-welded for you. Now, one thing I do like about this H-pipe from Pypes, is that it is a modular design, meaning there's a few different pieces. So if you ever wanted to switch out the cat-less portion here, for sort of the pipe's high-flow cats, well, you can do so. And you can get more info on those on the product page. Now, whenever doing a mid-pipe video, I do want to remind you guys that this is a full-length mid-pipe. And what that means is it's only going to fit 3-valve cars with the stock headers still in place or an aftermarket pair of shorty headers. Now, if you are looking to do a long tube/mid-pipe combo, then you might want to check out Pypes' other version of this same exact H-pipe, but the shorty version, which is designed to work with a long tube setup. Install is going to be slightly more involved than an axleback, for instance, but overall it really isn't all that bad, say maybe two hours from start to finish, using basic hand tools. Now, keep in mind, guys, most of this install will be done underneath the car, so just make sure you have your jack or jack stands ready or race ramps if that's an option. So if you guys are looking to add both power and sound to your 3-valve GT for a very affordable price, then be sure to check out the Pypes Off-Road H-Pipe, right here at AmericanMuscle.com.

Improves Flow For More Power. Add even more horsepower and torque to your 4.6L GT Mustang by eliminating those power robbing factory catalytic converters with a brand new Pypes Off Road H-Pipe. The Pypes off-road H-pipe will significantly improve your Mustang's exhaust flow for a notable increase in horsepower and torque.

Muscle Car Rumble. This free flowing Pypes h-pipe for the 2005 to 2010 Mustang GT not only increases power, but it also adds a deep muscle car rumble to the sound of your exhaust with its classic "H" crossover pipe design.

Modular Construction. Pypes unique three piece modular construction makes it quick and easy to add or remove catalytic converters to your exhaust system in just minutes, depending on your driving needs.

Durable Stainless Steel Construction. Pypes uses sturdy 16 gauge 409 stainless steel mandrel bent 2.5" tubing for improved exhaust flow and features welded reinforcement plates for additional strength.

Application. This Pypes Off-Road H-pipe is designed to be a direct bolt-on for the 2005 to 2010 4.6L GT Mustangs with either aftermarket short tube headers or the factory manifolds and a dual catback exhaust installed. Intended for off-road, track use only, does not include catalytic converters.

Will this work with stock tubing and after market axle backs? I want to install this in my brother's '08 GT. We want to buy an axle back kit and an off road H pipe and retain the remainder of the stock tubing. Is this possible?

Jln5685

  • Sure, you can install this O/R H-pipe between your stock manifolds and the flow tubes that would attach to the GT axle-back of your choice. If you have any other questions, don't hesitate to give us a call!

I have a 05 GT with stock headers and a Kooks cat-back exhaust. Will this Pypes mid pipe work with the setup that I have? If it does, do I need a tune?

Eddie

  • The Pypes Off-Road H-Pipe would work with this setup. A Tune would be required to disable toe cats and prevent P0430 and P0420 codes for catalyst efficiency

Would they fit on my 2005 v6 mustang with stock headers?

josem

  • Unfortunately based off the positioning and fitment on the V6, this Pypes Off-Road H-Pipe will not work on your vehicle as these are only intended for use on a 05-10 Mustang GT.

If I choose to add the cats, will the cats displace the H-Pipe enough to cause problems with stock exhaust.

JesseF

I see it comes with some tapered sleeves. I assume they go between the manifolds and the pipes with the o2 sensor bungs. Are they required for installation or is it an optional piece?

    Pypes off road h pipe

    The h pipe was shipped out quickly and packaged well. Install was easy but it needs a better clamp for the center. Got it together and it was leaking at center connection. To have the best results it probably should be welded, which is what I'm doing with mine. As for sound it really opened the car up. I have Bassani axle back and they really woke up . Has a great sound. Took the afternoon because I didn't have proper tools (extension and swivel) to get factory h pipe off.

    Pypes Offroad H-Pipe Slp Loudmouth Axleback

    So, after having trouble with the exhaust manifold stud and stripping it due to being so rusted, I eventually bought a new one and just got the exhaust all done, finally! :) I have the Pypes Offroad H-Pipe paired with the SLP Loudmouth Axleback (Muffler Deletes). Everything's done, matter of turning to the key to hear what it sounds like. I have never seen my buddy jump so high as it starts up and just BARKS! Idle is very loud, but does quiet down after a bit. As far as driving, anything over 1750 rpm is just ABSOLUTELY INSANE! 3rd gear going 30km a little throttle tap and broke the necks of a bunch of kids. If you don't like a LOUD and RASPY car I will have to say this isn't for you. But if your the kind of guy that likes to be looked at for having that loud mustang in town... You've come to the right place! Fit and finish was amazing! Taking the old exhaust off was the hardest part from all the rust and what not. Putting on new one was about 2 hours in the garage. By far the best $400 a Canadian could spend!!

    Put these on my 06 GT which already had Outlaw Axelbacks. I was skeptical on which to get the off road X or H. Stop debating and go with the H. Low rumble and no rasp even with my outlaws. Super loud :) my neighbors hate me now .

    Yeah, that's loud...

    I already had Pype Bomb axle backs, so I had a little bit of an exhaust note, the rest of the exhaust was stock. I decided I may never switch out the headers, but why not add some volume in the mid-pipe. Well....it's loud much louder. I've only driven the car about 50 miles and so far I'm ok with it. I had a rattle in my exhaust before I started, thought maybe I would find it, but now I have a couple of other rattles. Nothing too bad, because the exhaust is so loud you can't hear the rattles, lol.

    Easy Install - LOUD

    Very easy to install in a personal garage on a creaper/lying on my back. I also added the Pypes High Flow Metalic Catalytic converters. This configuration changed the volume and tone dramatically.....even with stock Flowmaster mufflers still installed. As my son put it, we are going for 'Smiles Per Gallon,' right.......and these will put a smile on your face.....maybe not your neighbors. Be sure to soak all bolts that you will be removing with penetrating oil and allow it to do it's job. I sprayed them the night before I started the work. A second set of hands is also helpful, especially removing the stock H-pipe that is all one piece. Without the cats, these things will be pure race car volume. Need a thumbs up icon here.

    The only thing I would suggest is that they came in a one piece set, like the stock h-pipe. Other than that, they're great, after a few adjustments.

    Holy Loud

    If you are looking to give your car that loud aggressive sound, buy this H-pipe as soon as you can. I'm running no cats, with SLP loudmouth exhaust tips and it is ungodly loud. It's the "hey look at my kind of exhaust". Would recommend getting high flow cats if you have muffler deletes to get rid of some of the raspiness. Overall this H-pipe for the money is for sure a great investment and will not disappoint!

    Pretty good buy

    I ordered this product and paired it with my flow master 40 axle back exhaust. The sound was awful. It was uncontrollable and sounded like my GT was packing 800 HP. I then put my stock exhaust back on in place of the 40s and now it sounds perfect. Definitely has a very nice growl. It is a tad bit louder than my flow masters were, but i can control the sound and it sounds like a normal mustang gt should. Great product, but i think it was meant to be paired with a pypes exhaust.

    PYPES H-Pipe

    I bought this product a long time ago, and just switched it out for a x pipe. Thats nothing against this product its an excellent product, i just wanted to see which i liked better. overall i prefer an H pipe it has a deep rumble and deep loud acceleration. this product does "trumpet" a little bit around 2.5K RPM but so do most other products, the only way ive noticed to get around this is changing headers. but for this price this is a steal its a great product i had it on my car for over a year and it wasnt hardly tarnished when i swapped it out. the fitment was great.

    $209 of SOUND and POWER

    The Pypes Off-Road H-Pype is unbelievable! The sound of my exhaust note is now amazing! It even adds low end power (extra horses) to give my mustang a little more giddy-up. Nonetheless, the focus of this product in my opinion should be around the exhaust note. Previously, I installed axle-back and cat-back exhaust systems, but was never really satisfied with the exhaust note. Too add to my anger, my friends new 2011 5.0 with Bassani axle-backs consistently diverted all of the attention away from my 2010 stang. HOWEVER!!! The Pypes Off-Road H-Pipe has revived my baby!!! The sound is so NASTY! EVERYONE'S HEAD TURNS! BIKERS, SOCCER MOMS, EVERYONE! My buddies 2011 5.0 only looks good now. To be honest, in order to get a great exhaust sound, all you need to really do is install this H-Pipe. Everything else can be factory and it will still scream! Youtube and other videos barely give these things justice. P.S. I am not a mechanic and therefore chose to have my H-Pipe installed at a shop. Do not pay over $100 for installation. Some mechanics and body shops will quote it being a 2 to 3 hour job requiring north of $200. This is a flat-out untruth. I had a PROFESSIONAL MECHANIC install mine for $80 in 1 hour.This was while he installed my H-Pipe and answered the shop phone.

    Installed with my existing SLP Loudmouth axleback

    This system really opened up my exhaust with a whole new sound! Really loud!! It's easy enough to cruise through a neighborhood or past a cop when needed just but throwing it in neutral or up shifting to stay in low rpm's. Start up in the morning or at night is a bit too loud for my neighbors- so they have complained already on day 3 lol; they will live though. Just need to get a tune now so the check engine light will go off! Very simple!

    Pypes Off Road H Pipe

    I got these a few days ago, and put them on this morning. Fit like a glove, all parts included, great finish, great packaging. As for sound, I have stock manifolds, the O/R H, and SSS Terminators. Sounds mean, heads turn. As for cruising, at 60 mph in 5th you wouldn't even know exhaust work was done, very quiet for cruising. Coasting in Neutral you can get past the police. WOT, the world will know you are coming. I would definitely recommend this for someone wanting to increase sound, and lose about 8 lbs.

    Holy Smokes She's Loud!

    Great product especially for the money. I was definitely skeptical at first as I have never gone with Pypes for any of my exhaust needs on any of my Stangs. However I am very impressed with this add. Not only is it very well priced but with a tune from Bama you can definitely noticed a pretty significant power gain and obviously the sound is amazing! It does have a big of a raspiness to it but it has settled down somewhat now that the exhaust is a little broken in. As far as install goes it went off without a hitch. The clamps provided are of good quality and you just re-use the factory bands for where the pipe meets the tail end of the factory exhaust! As far as paying the extra $40 for the extended O2 Sensors, I really don't see the point. The O2 sensors on mine were not a problem whatsoever and the pipe fit like a glove! Can't wait to do the headers next! Thanks AM for selling a great product and getting it to me fast!
