Description

Details

Now available from Lethal Performance is a great sounding exhaust combo kit that we have run on our very own 2015 Mustang GT. Choose from the Lethal Performance H or X resonator delete to go with the Roush axle back.

Lethal Performance resonator deletes are constructed from 2-1/2" 409 stainless steel. Includes all hardware and clamps to complete the install. Instructions are provided and also available for download for preview below.

The Roush axle back is built from 3" T304 stainless steel and features 4" polished stainless tips. Offers a very loud and aggressive tone during WOT and cruise, even when using the OEM cats. Watch the video below to hear how great this combo sounds...

Would purchase again
Finally got my system installed. Had a local shop that I've been working with for years put it on and even the employees there were very impressed. It has a great low tone and all the burps and rumbles you could ask for. However that being said if you get heavy in the throttle it will wake the dead. My neighbors sure don't like the cold start in the morning so it gets two thumbs up from me!! Review by Nathaniel / (Posted on 10/13/2016)
Roush Axle Back & H Pipe
Shipping was extremely fast. Items arrived two days after they were ordered. Installation was a breeze, taking only about an hour to complete. Now for the moment of truth, starting the car.... Wow! What a sound. Extremely happy. Review by 2016 gt/cs / (Posted on 12/27/2015)
Sounds Amazing!!
Had a professional exhaust shop install this system for me, they did a great job, they basically made me a catback system out of the parts, all welded together. Very loud. If you don't want to hear the exhaust inside the cabin stay away from this setup. Review by Geoff / (Posted on 3/10/2015)
