just bought a set of FRPP axle backs today,my first set of aftermarket exhaust. Question,do you need to tune the computer when switching from stock exhaust? It is for an 06 GT.

 

with an axle back no you dont....tuning your car for just having an exhaust upgrade is not needed. its just waste......but if you are boosted then when changing out a restrictive exhaust then tuning can help with performance.

the 06 should be fine

 

Thanx for the ininfo.,much appreciated!
