I was wondering if anyone knows if an off-road x-pipe will cause any computer problems (besides check engine light) and if it effects the car's life-span in any way? I've been thinking of getting a Pypes x-pipe full system for my '04 3.9L mustang. Thanks for any input.

 

You will need MIL eliminator to keep the light from coming on. Other than that, its just another peice of the exhaust.
