Best Sports Cat Downpipe that passes MOT ?
 

Im on the look out for a Sports / High flow catted Downpipe for a MY05 WRX that has the Prodrive Perf. Pack fitted, that will still pass an MOT emissions test.

Im told that a small centre section of the Exhaust has already been removed / de-catted as part of the PPP package. (a section that holds an oxygen sensor)

Which MOT-friendly downpipes do people recommend?

Cheers in advance.

i have a Zen Performance supplied (i think they use RCM items) 3inch down pipe with Sports Cat on my 01 STI JDM.

I thought i would have to put the second cat back on come MOT time, but Paul @ Zen says there will be no need.

I havent actually had a MOT yet, but come MOT time it should, in theory pass!

I have fitted a prodrive sportcat downpipe to mine, that is now the only cat on the car. If subaru fit it to a sti ppp then it surely must be good enough to pass the mot, although I have not tested it yet, MOT not due till August.

i fitted a 100cell ninja high flow cat from scooby world ..having recently had it on the rolling road it only took 6bhp of me over full decat and it scrapped throu the mot just so very happy with it ....but £300 is the price you pay for peace of mind

I've got the miltek system sports cat which passes (just when warm) However the cat is now in the centre section.

I have a prodrive sports cat on my MY02 STi and she went through the MOT in Northern Ireland just before I bought her and has since gone through the Irish NCT which has stricture rules on immissions.

I got H&S sport cat... very good...
