De-cat Up-pipe?


Recommended Posts

Posted

Anyone fitted one of these and if so how did it affect your emissions come MOT time? Already have 3"turbo back with no cat and was thinking of replacing the up-pipe too.

Any comments and info welcome

Cheers

When I bought my car, it had a 3" de-cat exhaust, from Downpipe back. Since then I fitted a 2.5" exhaust and it's made it soo much better. 3" with both de-cats is far too much for my non-remapped UK turbo, ruins the drive of the car in my opinion.

Planning on getting Apexi asap so i can get it mapped to make most of the mods, thinking along the lines of walbro, panel filter and possibly up-pipe before maybe sti8 top mount, td05 and 550s but think thats as far as i want to go.

Aiming for a reliable 300bhp

I have much the same set up - 3" turbo back with STi decatted up-pipe, walbro, panel filter, sti topmount, 550's and and a TD05 16G. It's getting remapped on Monday so keep an eye on the forums for what figures it makes.

Does a STi TMIC make any difference over a standard one like on my MY00 Uk turbo?

And....is there meant to be a cat on the Up-pipe to the turbo? Not sure if mine has one :rolleyes:
