4" Exaust=new sounds, concerns
Straight piped the truck the other day and wow it's a different animal. 
I can really hear the turbo now among other things and I do believe the engine is breathing a lot better. My concern is this, any long term adverse affects from such an open exaust? I realize this is rehashing some issues with long term psd owners but this my first psd. Also the ebpv mod, to turn it in to an exaust brake. Is this easy to do? This may be somthing I need to do before vacation in Sept.
Thanks again, Bill

yep that is a really awesome sound. no adverse affects from less resistance. the turbo likes as little backpressure after it as possible. it's alot easier on the engine.
here is the link to Kwikkordead's thread on how he did the EBPV to his truck

I've got 4" exhaust on mine, although it is not straight piped, my ONLY regret is that I never hear it unless I am next to a wall or jersey barrier.
For the exhaust brake, as long as you watch which color wire is which, you will be very happy with the results. I know I am.

should not be leaking this out, but my teacher is designing or in the stages of designing a Jacobs Brake system for the powerstroke head, that will fit under the stock valve covers. no one will be able to see it without an extremely trained eye. in reality i don't think it will happen, but i would be the first to have one.
