3" down pipe if you can get one with a 2.5" cat back system...
im. looking at making my own exhaust, i have a 1.8 cupra 180bhp i know all the milteks for my car are 2.5" but i was thinking of making it out of 3" can anyone help and give me some advice. thanks
Yer what part are u trying to make 3 inch because a 3 inch pipe won't clear the rear axle beem so in other words not doable
Where did you get the backbox from it looks smart ?
I am really sorry, do you mean the muffler?
