Title: Piperx downpipe or decat?
Post by: Leeds s3 on March 23, 2013, 12:11:20 pm

Is there any advantage of a 3" piperwex downpipe over keeping the standard downpipe and removing the cat?

The car wont be highly tuned just a ko3 with an intake and map.

Thanks

The OEM downpipe has quite restrictive bends so there will be a few HP difference  :happy2:
