Piperx downpipe or decat?

(1/1)

Leeds s3:
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

GrayMK5GTI:
The OEM downpipe has quite restrictive bends so there will be a few HP difference  :happy2:

berg:
yes, i felt quite a difference in my butt dyno when had my pipewerx downpipe fitted, i want full system later on
