Let me ask why you think it would be hurting you?

if the downpipe is still stock that may hurt a bit. put a 3.5" dp in it and youll be good. 4" sounds better

My 5" whistling is music to my ears. Can't beat it!

Sorry for the late reply been snowboarding in Austria, I asked this question before I researched and found out that the turbo maintains the back pressure so that's why I thought it could potentially hurt my performance... I was being lazy lol

5" like a boss.........love mine!

I remember when I was 5 inches, at like 13....

wait, nope, make that at 37....

i do like the sound of the 5 inch straight but damn the powermax gets loud!!!

5" is the way to go, nothing better in my opinion!

I have 4" on mine and my neighbors hate me, but they don't hate me nearly as much as the asshole with 6" on his cummins. I live in an apartment complex. I have the engine getting studded right now at Bleckman diesel. I'm excited to hear the mtw stage one when I get home at Christmas. I noticed a lot more power with a bigger exhaust and no cat or muffler compared to stock system.
