hey guys,
just a question with an old car of mine, it was a 96 wrx conversion,
tdo5 turbo,
3" exhsust, the guy i sold it too is having problems, subaru os park rekons the exhaust is too big and not enough back pressure,
i thought the bigger the exhust the better for turbo cars,
wats the deal?

Sounds like a pile of shit to me, everyone here has a 3" exhaust.

Tell him to get a 2nd opinion

i had 3inch on my 95 wrx (same as 96) and it only had one muffler at the back was very loud so there wasn't much backpressure and i had no problem so i don't think that is the problem.
Coilpacks on the end of plugs are a big problem. If that is the problem convert to BOSCH coils (can't remember the number look up RS liberty forum) that are mounted away from plugs.

Bosch Coils Upgrade Part No = HEC716

As for the TBE... when it comes to turbo engines, the bigger the TBE the better!
