So....2 x 200=400 400 + 250=650 650 + 250=900 +50(approx for fitting,hangers, brackets etc) £950. I did the math as per your request and that seems pretty close to a grand for you to start getting all precious over your comments bring taken so literally, 50 quid here or there doesn't make any difference really when your pricing structure is already so far beyond correct, hell, make it 2k, sod it, 22k. Get back in your box, you got it wrong through your own stupidity, you can't start having a go at other members who do actually have a clue because of that. OP, regardless I would also advise going down the decat route, tbh the price seems quite reasonable IMO, but there are a couple of other thread with people doing the same thing, also you could PM al on here, in the traders section-awesomegti(?), he knows his stuff when it comes to exhausts and tuning, and if he can't help personally he'll be sat next to someone who can.
