I'm in the process of adding some choice mods to my car for a little more power []. I was wondering if the following exhaust/turbo set up would pass an emmissions test:
WRX MY06 2.5.
Full decat Up pipe - VF34 Turbo - Sports catdown pipe - de-res centre - Prodrive BB.
My intention is to go with the regular up pipe (MUST be legal) and keep the power down to prevent the uppie from breaking up, but if a decatted uppie will be legal, then I might as well do that while I'm at it (providing I can source it on the cheap!).
Thanks for your help.
John
