I paid something like 5 and change for mine but I supplied a muffler and tips...
Basicly he copied my existing VM2 which was all beat up and made me the samething. he worked almost all day on it, labor is where the $$ went.
He has a very meticulous exhaust guy there.

Never. Backpressure only matters for NA motors, turbo's create MORE than enough backpressure
theres never too little backpressure on a boosted motor. The more free flowing the exhaust, the better. I recall dyno charts of cars with dumps gaining around 38whp, with all other things equal to a catback run.
