I have a 06 wrx wagon(Mods: Stock intake, cat-back, accessport stage 1), i'm looking to run a catless downpipe with a pdx tune or a etune if anyone has suggestions for stage 2+ which might include a 3 port maybe and a up pipe or ewg setup for future big turbo . My question related to maintenance is where is a good shop to go to for a inspection sticker, i'm due for one in May but i'm looking for shop to pass me with a catless down pipe/primary cat still installed to resonate some of the noise and fuel. My car is all up to date maintenance wise. For the people running a cat less divorced pipe, how do you like it? and i believe a e tune should be fine instead of a OTS map for just going from catted to catless. Thankyou. By the way i am in Berwick, ME near portland, york county.
