Comptech SC, otherwise stock.

Im guessing the rowdier it gets, the free'er it flows?

What setup provides the best power increase.

How is the comptech exhaust?

Do I need to go single?

I hear good things about the Invidia exhaust. Is that the one to get for a blown car as well?

THanks.

I'm also interested to know if the Invidia is a good exhaust for a SC. I am thinking of getting FI in the near future and I have this exhaust.
