So I'm new to the diesel scene,
and I gotz me two stupid questions.
1) I heard some guy with a Ford Excursion the "whistle" coming off his turbo was loud as hell and sounded cool. (at-least to me)
Is it that way due to an after market turbo??
2) The big ass exhaust tip, whats the benefit? does it change the sound?
I have a f-250 with a Edge juice programmer, K&N air intake and a 4" RBP exhaust all the back, I think its a 4" tip.
