Aye, but you got the cat pipe ULTRA cheap as this was excess stock![]
Dave,
The STI sportscat downpipe is a bstard to fit on a WRX so, I widnae bother mate[N]. for a good start go for a decat pipe which removes the third cat and a centre section and once you want to spend £550 on a remap get a decat downpipe (£160 delivered) and bobs yer uncle.
Alternatively, get a TSL or scoobyworld sportscat downpipe c £300-350 and a decat-pipe and centre section if you dont want the MOT hassle and you can leave out a remap with that package.
Check out my Scottish Scoobies special in the For Sale section as I'm currently doing a decat pipe and centre section for £200 delivered[]
