would it change my fuling if i got a straight through mid-pipe,been thinking of getting 1 as the old 1 has a small hole , there not much and would just cut it out.would i have to change any fuling ect or would it just fit in and work fine ?
If you have a decat downpipe and aftermarket backbox, I would be checking for boost spikes and leaning out.
If not, I would stil lget it checked anyway.

i dont have a de -cat and the exhaust is a kps 1 but the mid pipe has gone.ill get 1 and if i see a change in the car ill have it looked at,prob best bet .
