I forgot to mention to you he was going to put the SPRINT Booster I will call him today to see his results
Your completely right. Thanks.I guess our DPF really restricts alot of power/sound for us Maybe the d should just stay as a sleeper

But when driving the sound is about the same....
I know what your talking about. It def does. I really wanna hear those turbos too
I'm not looking for all around loud, just when I get on it

Your right, I guess exhaust is kinda stupid without the correct tune. Someday though, I will get ReNNtech or Evolve.

The exhaust at any given car usually renders anywhere from 7-10 whp if so, unless your driving supped up 911 or GTR then its a different story but i doubt you will gain 10 whp on a DIESEL. i might be wrong on this though!!
Did you have the JBD before your ReNNtech or is that 70whp gain from stock?
Thanks for the tip though
