Tune Required After Install? Would a Tune be required after this install?

STANGBOSS

  • It is highly recommended to get the most performance gains. Removing the cats will have much higher airflow. Your check engine light will also be on after removing your cats so you can also have that turned off with a tuning.

tune and fitment Would a tune be required? Would these go along with my pypes pipe bomb axle backs? Thanks

Aukward

  • Any time you make a mod to your coyote engine - you should get a tune for that change - the car performs better. Also - if you don't get a tune - your check engine light might come on due to the oxygen senors> I had the error codes for Oxygen errors on my GT when I installed these H Pypes. Once the Tune was done - the Check engine light went off.

i have an Pypes axle back exhaust will this bolt up or will i have to have some mods done?

  • The mid-pipe and axle-back do not directly connect. You will not have any issues installing this with any axle-back.

    Impressive

    I purchased the Borla Atak exhaust first to improve the sound of my 2012 gt and it did just that. The sound was just want I wanted at first but like anything else you get used to it and eventually want more. After deciding to go louder I purchased the pypes off-road h--pipe and it did just that. If you want you exhaust to be loud enough to wake up the neighbors and scare small children then don't hesitate and purchase this item.

    Sounds really loud. Gain about 10 RWHP.

    Top speed on 1/4 miles increased from 109 to 112 after install the o/r H pipe. It's just too loud for a daily driver. Also, cat delete is going to make your car smells terrible. If you drive a convertible, I don't recommend it. If you want to improve your 1/4 miles time, I strongly recommend it.

    LOUD

    I had these put on with pype bomb axle back, and it's crazy loud. I attempted to install myself but could not get the factory clamps that you have to use to stop leaking. Had a shop do both items for 100 bucks. I recommend a shop install unless you have a lift and or very mechanically inclined

    Mostly painless!

    The install actually went quite well. The instructions were very clear (even though it's a touch of a no-brainer). Finish of the pieces was impressive. I was a little disappointed to see only Grade 5 hardware was included for header-to-H pipe attachment. Grade 8 would be preferable as Grade 5 hardware tends to not last as long in that location. As far as fit, it's mostly good. I don't know if the fitting of my axle back has caused some misalignment or if the H pipe just needs a little tweaking. I couldn't get the passenger side downpipe to midpipe connection to line up very well. Therefore it leaks pretty badly. This is all due in part to the HORRIBLE factory band clamps (I miss the flanges of a new edge!). My solution is to have it welded. The sound is great! Much fuller tone, much more volume, and a beautiful rumble at idle now. Install and enjoy!

    Provides A Deeper Tone

    I have been trying to achive a deeper tone with my mustang. I am currently running the pypes super cat back. It is too raspy for me and i was looking for something to bring the deep tone back to it. This did a good job and changing the tone but still its too raspy for me (but that is the pype bomb exhaust i have). The whole time took me about 2 hours. It took about 1 hour to get my car up high enough to get to the stock H pipe. But once i go that, only about 45 min or so to get the old one out and new one in. Bang for my buck for me is only a 3/5 because i live in CA - so i didnt install the cat deletes (not yet). It would be nice if they sold the deletes and the H-pipe separate for this type of situation.

    Perfect

    Sounds just like I hoped it would. Got this and Pypes Pype Bombs together. You will definitely KNOW when I head down your street. Couldn't decide between X or H and am glad I went with H pipe

    This in an awesome offroad H...

    First, i was a bit leery about purchasing this without more feedback. However, the first set of cat backs I had were Pypes, and they were good quality, so I rolled the dice. Installed these without help on jack stands. Header-to-cat bolts are 15mm, one on each side accessible from the top, the other accessible from underneath. The nuts on top required a 24" extension and a 24" breaker bar to pop loose (keep in mind, this car has less than 11k on it). That was the only difficult thing with this install. All welds were of great quality. Pipe bends were top notch and everything fit perfectly. The instructions called for cutting the claps from the factory H, so not sure why the previous reviewer took issue with it. Great sound, very similar now to a pushrod 302, when coupled (at least) by my Roush catback. Highly recommended.

    Enhanced my Roush axleback exhaust!

    One issue during install. The 2 factory clamps that are to be used after bolting the upper section to the manifold are welded to the factory exhaust. The shop that did my install gave me the option to have them removed and tack welded to the new h pipe or they would weld the new parts together. Thats why I only gave 3 stars for fit and finish (otherewise fit and finish were superb)!

    Worth every penny! Here are some install tips..

    Let me start off by saying I could not be happier with this H pipe. It looks beautiful, it fits perfect and it sounds amazing. I always liked the rumble of an H pipe over an X pipe, and this does not disappoint. I only had a set of GT500 mufflers, and this system unleased the beast in my mustang. What I like most about it, is I am not looking for an exhaust that wakes up the neighbors, but I want something that lets people know that a mustang is coming, and that's exactly what this does. With that in mind I have some tips: First, I called several shops, both chains and small shops, and I couldn't find any that would delete the cats for me. They all are worried about the EPA, so if you buy this, plan on installing it yourself. Second, as mentioned in the install instructions, make sure you have some penetrating oil, and make sure it is stronger than WD-40. I tried that first and ended up going and getting some liquid wrench because those rusted bolts would not budge otherwise. Even with the liquid wrench, plan on working to get those bolts loosened. I had a 1/2 inch socket wrench with about 30 inches of extensions on it, and that took every ounce of strength I had to break those suckers loose from the top. Then breaking the other two loose from the bottom, I used a crescent wrench, and hooked another one on to use as a breaker bar. I found that worked quite well. Third, having the right tools can make things go a lot faster. You will need a 15mm socket for the stock bolts going from the down pipes to the exhaust manifold, as well as for the clamps going from the stock H pipe to the mid pipes. You will also need a 13mm socket for the clamps going from the down pipes to the H pipe. When you switch over to the Pypes set up, the conecting bolts from the exhaust manifold are going to be a 9/16 size, and make sure you have a wrench too so that you can hold one side of the bolts while you tighten the nuts. And finally, when you are installing the new pipes, use a floor jack and a piece of wood to lift up your mid pipes that are hanging down. It is dang difficult to try and hold everything level, while tightening it down. I tried it the first time without doing that and ended up with exhaust leaks out of every break in the pipes because the whole system was sagging. The next day I loosened everything, and when I lifted up the mid pipes I could just see everything line up and fit better. I apologize for rambling on, but I made a fair amount of mistakes that led to this being a much longer process than necessary. Hopefully this helps you avoid some of the same ones I made.
