Ok I'm considering new exhaust. Here is what I have currently.

PacBrake turbo mounted exhaust brake to stock downpipe with everything stock except no cat or muffler.

I would like to increase the size of the exhaust for better flow (I'm going with a stack in the bed - finally talked myself into it) but should I go without the turbo mounted brake in favor of an inline exhaust brake for better flow or will it really matter in the grand scheme of things?

 

anyone have any suggestions??

i would guess the answer is dependent on your power goals. the more power you build the more you're going to have to try and weed out any and all restrictions.

 

Well, if you plan to stay with the stock turbo I would stick with the turbo mount unit you already own. When going to a bigger turbo, you will have to move it.
For the exhaust, you can get single and dual stack kits turbo back.

 

I believe any turbo monted brake is a 3" restriction...

Ultimately, inline is better.
