Can definitely tell the difference in sound and a huge difference in the exhaust note. 5 hours labor. Good low note until about 30mph then the car starts to rip like a muscle car should!

I have a ford racing axle back exhaust currently on the car will this fit with this system or will I have to make some bends and welds?

  • Your FR axle-back exhaust doesn't directly bolt up to this Long Tube Header/Mid-pipe combo. The shorty x-pipe in this kit will bolt up to the factory flow tubes that your current mid-pipe is attached to. You can use this Header/X-pipe combo without any issues! Enjoy!!

MIL Any Check engine light issues after installing this product?

CaptDan Year: 2006 Model: GT

  • This Pypes Long Tube Header and Off-Road Shorty X-pipe combo would throw a CEL once installed due to the removal of the catalytic converters. A Bama custom tune can be used to turn off the CEL and is also highly recommended when doing a Long Tube Header install to obtain maximum gains from the upgrade. If you have any questions, don't hesitate to give us a call!

    Great Kit

    Awesome kit, install was simple, just somewhat time consuming if your doing it on your back, but well worth the labor. Exhaust sounds great, can definitely feel the difference in power, car keeps wanting to pull. Was concerned about the X being raspy but its not to bad, at least with my magnaflows. Overall this is a great pick up and Its always turning heads.

    Great product for the $$$. expected a little more growl

    I am writing this review a few weeks after install. Before the headers i had the stock shorties w/ catted Pypes X pipe and Roush axel backs. The car was already pretty loud but wanted the deeper growl and better flow for more power. The install was fairly easy and the gaskets included are far better than expected. I wasnt aware that Pypes included gaskets so i had bought FRPP gaskets but ended up returning them. Total install time was about 3 hrs. Overall I am pleased with the product. At idle the engine is slightly deeper than before but that might be because of my prior setup. BUT, at full throttle she comes to life and is very loud just not as deep as expected. You can def feel the torque difference and makes burnouts that much more fun! ;) I have a buddy that has similar setup as me but has Kooks headers. Honestly, they sound the same. Cant beat this price!

    Sounds AMAZING!!!

    Just got back from pickin my car up from the shop. I have to say, this set-up sounds AMAZING!!! EVERYONE turns their heads when you step on the gas, thats for sure. I don't know how much power I picked be honest I dont feel much of a difference, but it was well worth the price.

    Pypes LT's

    Installation of the headers is a breeze. Fit and finish is top notch. The X-pipe was a bit more difficult. Ended up having it welded up to fit. it's not perfect, but it works.
