Whats the best de-cat up pipe for my wrx Blobeye
 

Hi guys where is the best place to get a decent de-cat up pipe from for my 2004 Blobeye wrx and is a 100 cell sports cat a good idea for my down pipe if I want it to go through a mot without having to keep swapping it back to standard

Harvey smith spec one.

I would go for an Sti uppipe.
Should be able to pick a cheap one on here in the for sale section.

Harvey Smith up-pipe - might even improve spool and response (dont just replace it - make it better)

CobraSport 200 cell downpipe - well priced and never worry about a MOT again. (some 100 cell sportscats have issues)
