I believe you might need SOME kind of backpressure to run your turbo correctly.

it wont hurt anything ... it will help for spool time actually youll spool faster. only problem is your not using your rear o2 sensor now

I thought turbos were unhappy without a little backpressure, it may spool up faster, but I how would he get the same pressure?

The turbo is the only thing that causes the back pressure... are you on crack?

yea you'll most dfinatly be able to hear that thing spooling lol. i had a friend w/ a turbo'd CRX w/ open down pipe and we could hear that thing like 1/2 mile away lol. spool time is decreased b/c the turbo doesn't have to work as hard. another thing that wil help spool time if you do't arleady have it is a 3" o2 housing.
