4in exhaust

[Hansen01]

well got my 4 in exhaust on today, and it made a huge difference, dropped temps about 200 degrees, made turbo spool up a bit quicker and not near as much lag, overall a good investment, got it from tv diesel came with downpipe and all, fit well back to the stacks i dont quite have fineshed yet

I love my 4" system, makes me smile every time I go for a drive.

TV gots a good deal but my downpipe was a little wrong so i had to fix it but alls good now

[Hansen01]

really? what was wrong with your down pipe, mine was perfect hoping to get my stacks hooked up tonight its awful loud right under the cab

[91bluecummins]

the end of the down pipe would not line up to the next piece , like the down pipe was at the wrong angle and if they were connected right it would hit my tranfer case . But i welded it in the right place for best clearence

well mine was real close everywhere, but that could be because everything on mine is 5inches farther back than yours (6speed)
