Decat Downpipe question

(1/2) > >>

burt2000:
Hey guys,

Are these all much of a muchness as there seems to be a massive variation in price?

Im currently after a 3" tappered decat downpipe so that i can go to stage 2 on my Mk5 GTI and have found the likes of the one linked below around £160

has anyone else got these or similar ebay ones and find they do the job just fine? surely as long as they are welded properly they are all essentially just a 3" piece of stainless steel :confused:

The grade of stainless steel varies quite a lot. Some will look very good quality when they arrive, but after a winter of salt they show the poor quality of the steel up and rust badly. Also some have stainless piping, but a mild steel flange up to the turbo.

been looking at the pipe werx one, it looks a nice job but isnt taperred :sad1:

What's the idea behind tappered DP's

burt2000:
so you can run the standard cat back with the decat downpipe and go to stage 2 remap :happy2:
