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

Adding/Removing Catalytic Converters I'd like to run this setup with the Pypes ceramic cats. However, I would like to be able to remove the cats from time to time. So here's my question(s): Just how easy is it to add/remove the cats? It seems like removing the catalytic converters would leave a gap in the exhaust system... wouldn't you need short straight-through pipes in their place?

  • Yes, it would leave a gap, you would have to keep the additional pipe area (that was initially cut out) and clamp it back in to place with 2 clamps when the catalytics are not being used.

Will my check engine light come on and will I need a tuner?

  • Your check engine light will come on because of the absence of a catalytic converter. The tuner, depending on what type, would allow you to turn off the check engine light.

Should I get these for my 05 GT on my 05 GT I got the BBK Shorty Headers and the SLP Loudmouth Axle-Back Exhaust, and I wanna get new midpipes. What will sound better, the X-Pipes or H-Pipes?

  • Hello Landen, It all depends on what kind of exhaust note you want. The "H" pipe produces a deeper sound. The "X" pipe produces a raspier sound. Always helps to listen to other Mustang owner's exhaust setups so you can get an idea of the sound. 2fast08

    $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.

    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!

    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!

    H-pipe review

    I had an x pipe on my car previously and I will say, hands down, the H pipe has a way better sound. If you are on the fence about what to get, read no farther, get the H pipe! I don't know why all the aftermarket companies are so bent on making X pipes, the H sounds soo much better, I can't say it enough.

    Great loud sound!

    I love the sound of my exhaust now and I can't stop driving my car. I've got this paired up with my MAC exhaust and man does it sound great. I knew this was perfect when I first started it up and my wife looks at me and says," Oh man...our neighbors are going to hate us." I also loved the fact this product came in 4 pieces which made installation a piece of cake.

    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.

    Loud!! Muscle Car Sound

    This H-pipe is loud and I mean loud, if you want a head turner i say go ahead pick these up. This is a perfect setup with my Flowmaster American Thunder Axle Back mufflers. Check out my video on how it sounds. http://www.youtube.com/watch?v=FLXWvKbJ3I8

    a must have!!

    I thought my mustang sounded good before. I was wrong. My 05gt sounds bada** now. It's actually quieter in the cabin of the car when I'm going slow or below 3000rpm, but past 3500 and my car SCREAMS!! If you want a louder, more aggressive sounding ride, take my word and buy these now. Don't think twice, just do it.

    Really frees up the top end!

    If you want more top end out of your 4.6 this part is what you need. Yes, it significantly increases the volume of your exhaust and I would suggest not to use with chambered mufflers, it just didn't sound "right"

    Extremely Loud

    I was pretty excited when I ordered my H-pipe. I researched and read all of the reveiws on this site a few times. Obviously I was expecting loud, especially since I already have an slp loudmouth exhaust. After reading the reveiws I went ahead and bought it. Install is pretty easy. If you have a lift it should take no more than a few hours. You may want to think about welding as the clamps that are provided are a little loose. I decided not to weld until I was absoluetely sure I was going to keep them. After the install I fired it up. WOW it was loud. I loved the start up sound. It sounded pretty mean. It idled quite nicely and wasnt much louder then the set-up I had before. Now for the negatives. Yes I like loud but this is just obnoxious. I slowly drove out of the parking lot and as soon as you go past 2000rpm it just fires up. Dont get me wrong I knew what I was getting into and was expecting loud but c'mon. 2000rpm and it sounds like Im punching it. Driving down the road it sounded like I didnt know how to drive manual and I was always in the wrong gear. Their is a big difference between a ahead turner and a head shake turner. Blocks down the road I could see people looking at me like I was an idiot. If you live around neighbours you will get some pretty nasty looks as well. Just starting it up early in the morning would wake them up 5 houses down the block. The sound is very comparible to a ricer which is not what I want for a 300hp v8. You really do lose the v8 sound as its drowned out by a loud raspy tone. I went back to the shop the next day and had it removed. American Muscle was great to deal with as always and through no fault of anyones but my own Im just not satisfied with the product. I realize everyone of these reveiws will tell you different but TRUST ME!, if this is your daily driver then you will not like the sound. Think of your everyday lifestyle and ask yourself if you want to "be that guy" Hope this reveiw helps.
