Turbo Back exhaust Cause turbo Problems?

I was talking to a mechanic at a shop the other day and he said something about needing the backpressure of the cat when doing an aftermarket exhaust otherwise with a straight turbo back exhaust it can create problems with the turbo. Any cred to this?

A turbo needs no backpressure behind the turbo. Backpressure behind the turbo will actually cause it to spool slower. I run straight exhaust to stacks and have had 0 problems as well as MANY people here run straight pipes.

Yep, these engines do not need any backpressure. End of story.

A naturally aspirated gas motor needs a little back pressure but in any kind of turbo application back pressure is not your friend. You probably want to take other advise from this guy with a grain of salt.

If I'm not mistaken gas turbos work the same way in that you want that exhaust gone as fast as possible. Maybe you want to stop talking to this guy all together for advice...
