well im gonna ask tomorrow if there will be any gains from getting this exhaust
I paid 500 quid for my 182 custom system mine, is a cat back single backbox (mounted on custom brackets (AAS made these)), 3.5 inch slash cut. i got discount cos 3 of us went together.
Myself, my brother and hutchie.
Ive had one for a few years on my 172, got it done at burnley which has an excellent reputation. Its loud but thats what I asked for. Good enough for me.
