I was thinking of doing a full custom turbo-back setup. Considering eventual N/A cams, bigger injectors, moving up in turbo from the 15G, and an ECU tune...but will basically stay stock until the money is right.
I've been to 4 shops so far. Threw down the specs of going 3" all the way (downpipe, cat, resonator where the stock muffler is, straight-through muffler at the rear, and all piping in between). I'm looking for CA smog legality and keeping the loud exhaust tickets away from me, not to mention being all set regardless of performance goal. However, after 4 shops and meeting a cat who got his 855T done, conflicts with my idea go as follows:
-2-1/2" will suffice b/c 3" is too big unless I had a huge turbo right off, and I'd probably lose power and torque.
-the stock cat can simply be opened up to whatever size piping I use.
-custom downpipe may not be smog legal.
-turbo cars aren't loud like that to require a resonator in addition to muffler.
So those of you who have already had one done, what is the best compromise?
Also, O2 sensors have thrown a CEL, so I want them to deal with that too. What would I need them to do there?
