? about 5 inch exhaust ?

[outlawed_LLY]

Down pipe is worth it for the change in sound. No more un-Godly screech at WOT. It also doesn't require transmission removal to change.

I would look into either a Flo-Pro, MBRP, or a Husker Kit. My DE fit like absolute shit, I now have a MBRP 5" straight kit and it fits 100x better than the DE. Might just be me, but those are my recommendations.

No, you need a new downpipe if you want to go right off the back of the turbo, all you need to do is remove the 2 bolts holding the transmission dipstick to get enough room to remove the downpipe. 3 bolts on the turbo heat shield then just flip that back, undo the clamp and the top and bottom and it should pop right out.

When companies say "turbo back exhaust" they mean from the down pipe back. The stock down pipe is 3" I think... The companies count the downpipe as part of the turbo, hence the name "turbo back exhaust" just means it cuts the cat out.

It may be 3" but they squish it down quite a bit in spots, there's pictures comparing the stock to aftermarket and you can see why so many people do it.

Yea it's 3" but almost bent in parts so it doesn't flow like you think it would... Thanks for clarifying

Wow, Rodger. I guess I never noticed how many miles you have on your truck. That's awesome!

I just did DE down pipe and DE 5" straight exhaust. The 5" is actually 4" until it gets to where the cat is. That is where it bumps up to 5". Spray all of the nuts and bolts the day before with PB blaster. Take your time and be patient. I hated my DE exhaust the first night, it just did not fit correctly. I went in for the night and had a couple beers and thought about it. Got up the next morning with a clear head and everything fell into place. I could not be happier.

I just installed a 4" MBRP DP or turbo back exhaust with a 6" tip, nice aggressive sound with the MBRP through muffler, no excessive cab noise and nice boost in acceleration. I haven't done the down pipe yet but thinking of going with the the MBRP 3"....installation time on the exhaust on a lift was about 2.5hrs total-removal and install, no issues at all with this system...

Stock Compared to Profab Downpipe

I put a 5" Diamond Eye on mine, the fitment was horrible. I ended up welding it up and using only 2 of the hangers/clamps that came with it. I will not buy from them again, but it sounds good though. I doubt brand has anything to do with the sound though lol.
