The reason for a special exhaust for a turbo kit is that you need to have a as much of a free flowing system as possible.

Backpressure on a turbo'd car can be a bad thing. Wit as much air as the turbine is shoveling through the engine the subsiquent gasses need as much space as possible to escape.

Stock cars run about 6-8lbs of back pressure, slightly modded N/A car will have 3-5lbs and a turbo car will generally have 1-2.5lbs. Go with a minimum 2.75" dia. piping for the exhaust track and if you plan on going "mad boost" then 3" all the way is a must.

The best exhaust for a turbo is no exhaust at all.<img src=/images/forums/snitz/smile.gif width=15 height=15 border=0>

Not true Lantra. A 4-cylinder car needs some backpressure to operate efficiently, even if it is turbo.

Yes, but the turbo manifold itself creates the backpressure for the engine, backpressure after the turbine does you nothing. After the turbine you want as little backpressure as possible.
