Got the down pipe the other day. So tonight we got rid of the old exhaust. Put on the down pipe . Tomorrow it gits a 3" exhaust back, straight back.
So since we had just the down pipe on, we had to take it for a ride. There was a difference in power, spool up, and sound. At idle you can hear the turbo purring.):h The truck seems to like it.

pretty bad *** sounding isn't it?

sure is! i run 4" straight pipe and its awesome!

i remember my 6.5 days....i loved my 3 inch down pipe...sounds good
