get a flowmaster with 3 inch inlet/outlet. it will give a good sound but no tickets. theyve got a whole line of turbo mufflers.

 

Am running a straight 2.25" pipe with no Cat. converter on my boosted civic. My shit spool fast as hell. Good power from mid-to top

 

no exhaust!! ricer!!!

 

shut up.
You know my shit is on back order. Still waiting for it

 

Please explain. Are you talking turbos or exhaust piping?

 

Yeah, im gona need you to explain that.

 

Not a problem. This usually affects stock turbo cars and cars with custom turbokits that have internal wastegates and large unrestrictive exhausts. Basically the problem comes with the fact that the exhaust outflows the wastegate. The wastegate cannot divert enough exhaust gasses to limit boost properly. In the end you get inconsistent boost pressures or even uncontrollable amounts of boost. This is called boost creep and what happens is that you set you boost to the desired amount, but as you accelerate hard the boost will hover at what you set it too for a second then in higher rpms it begins to rise uncontrollably. I had a problem with this before I upgraded my wastegate, I would set it at 15 psi and at redline I would actually be in the 23-24 psi range. There are certain things that you can do to help with boostcreep, but the best of course is an external wastegate.

 

its not the exhaust its the additional airflow the exhaust allows the motor to pump. The wastegate becomes too small and the extra air is backed up and goes through the turbine when it should be going through the wastegate, when this happens turbine speed goes up and with it; boost.

 

i don't think those are straight-through, and i know they're overpriced.

dynomax race bullet mufflers. 2 or 3 of 'em - 3"-3.5"

you got tickets for your old muffler because it was chrome and gay. get large, free-flowing exhaust, and don't put a chrome tip on it. you'll be fine. seriously.

yea - what he said. with a turbo, running just a downpipe (if not even less) as large as fucking possible should always be ideal.

 

Exactly. Ill say it again, you can never go with to big of an exhaust on a turbo car. No exhaust=best.
