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 and removes all 2" sections from the stock exhaust, something no other resonator delete does.

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...
