hi, since registering on here I've been reading loads of threads to try and educate myself, but I cant answer this question, so here goes......

I have got a 99 t plate uk turbo impreza which is 100% standard. I would like to replace the standard twin pipe exhaust with a stainless cat back.

once fitted will the car need to be re mapped?

On a classic you'll be fine if its just a cat back.

Yea it'll be fine. Just stick a 2.5" cat back system on.
