3" downpipe
 

What do you guys use?

I have a 3" buddy club (yes I went for he loud option) exhaust to go on but need the downpipe first. I currently run a japspeed turbo back system but it's all 2.5 bore and wondered what other are using on their gc8s

I have a 3" sports cat downpipe fitted to a fujitsubo 2 1/2" stainless system (on MY95 WRX). They're joined together with one of these: http://www.ebay.co.uk/itm/GrimmSpeed...item3ce2cde64e
Great performance (much quicker spool than the standard cat), but a fair bit louder. Just praying it'll get through an MOT when hot...

I've got a 3 inch system on a 2 1/2 inch downpipe, there's just some donut gasket squished in there. Works fine if you want to get your system fitted up before you get a downpipe sorted.
