Default 06 WRX mods

Would yall recomend a bigger intercooler (top mount), downpipe and catback on my 06 WRX or am I asking for trouble ie...throwing codes or not passing emmissions? And what kind of brands are reasonably priced...oh and 3" or 2.5" piping?! Any info would be super.

many parts too list


If you install a TB you need Engine management...I went with the Cobb AP. If you dont upgrade the turbo a bigger top mount is not needed. My suggestion to upgrade to good power without damaging anything is a vf-39, sti tm, TB and EM. Thats if your serious about upgrading, I have that now and Im about to step up to a 20g.

i have a 3" catback and STI intercooler with stock tune and my car runs like a champ. no codes or hesitations or anything. I also have a full 3" downpipe waiting for EM.. you can always get a catted downpipe to stay within emmissions.. I have an OmG BlitZ toO LoUd cat back but i think it's fine, it's all in preference, so just look around, watch videos haha. i had an old exhaust thread that people posted pictures of their exhausts to see what looked good.
