Best exhaust manufacturer for 6.7??

[smokin_h]

Im going to go all out and do my exhaust right for the first time . What is the best manufacturer doing a 5" downpipe back stainless kit? Would you do a muffler or not? Thanks!!!

I've got the FloPro 5" stainless no muffler. Wouldnt choose anything else.

You can't really go wrong with anything stainless and mandrel bent. Although I doubt anyone is selling crush bent 5" exhaust for these things! A DPF back kit won't do anything besides change the look. It will not make it louder. If deleting, then anything stainless Downpipe-back is the way to go.

MBRP or AFE are going to be the two highest quality kits on the market. I personally recommend MBRP.

its all cosmetics if you arent going with a muffler. I say go with what your wallet tells you, your motor is going to be making all the sound anyways

This is what I've got, and the guys at Performance Truck Products are great to deal with.

I went with AFE. It actually came in today. Had it installed about 2 hours after I picked it up from the house. I love it.

I'm running a 5" MBRP down pipe back system with a 5" ID 6" OD tip without a muffler. I wouldn't go any other way. Fit and finish is top notch, installation was a breeze, and it will easily out last the truck. The only hiccup in the install was cutting the one pipe because I have a CCSB. MBRP exhausts come set up for the CCLB configuration which I didn't know, but the instructions are extremely clear and takes five minutes to cut the pipe to the correct length.

I do ALOT of driving (truck is 2 1/2 months old, has 12k miles on it, bought with 2.8 miles on it). I have had zero issues with the noise or droan. Even towing my 8.5x20 toy hauler the exhaust is barely audible at cruising speeds with the windows up. With the windows down you can hear the exhaust, but can still easily hear the radio or hold a conversation at a normal level. Nothing can compare to the sound of a full 5" system when you go WOT on these 6.7 motors though. My 6.4 with the 350 tune and full 5" doesn't sound as good as my 6.7 imho.

I was initially going to go with MBRP but it would have taken a few weeks for it to ship so I went with the more expensive AFE. Even the AFE was supposed to take about 3 weeks but it only ended up taking about a 8 days. Install was easy as well. The AFE kit you don't have to cut. I initially had the center pipe for a long bed installed till I realized that it was for a long bed. No muffler either. I think it sounds awesome. With windows up I barely notice it unless I'm at WOT. Windows down it sounds like a diesel should. lol

OP, you can't go wrong with either MBRP or AFE. I'd recommend no muffler but that is just personal preference.

There is more to it than cosmetics ie. fitment, hangers, warranty, tip, etc.

All pipes are not created equal.
