2012 6.7 exhaust?

[Cesar84]

I was wondering if anyone was using the diamond eye 5" and how you liked it... I was debating 4" or 5" and what the pros/cons of each were...TIA

I've installed a few Diamond Eye exhausts on various trucks (obs, my 6.4, 6.0, 5.9, duramax), and honestly the fitment on every single one was a pain. the OBS i'd say was the worst imo. Preferably, Flo-Pro is my choice.

I have always used mbrp in the past. I used flow pro 5" on my 6.7 and it all went together really good! Call Mike at No Limit he will get you setup

My 5" Flo-Pro went on with 0 problems, sounds amazing.

Thanks for the replys ill have to go with flo pro.. Do you all know what is the difference between the 4" and 5" is there any performance difference or just sound

Just sound, more drone in a 5", but still not louder than my tires... But yeah a 5" is deeper in tone.

I'm happy with my 4" flo-pro. I didn't think it sounded that good till I finally heard someone else driving it.

+1 for flo-pro I have 5" on mine and love it. Fitment was great too, install was super easy

Another flo pro owner. Love the sound of the 5"

Flo-pro SS 4" with a 40" muff here. A little louder than I would prefer, but a nice tone when I'm on it. Went together great and I'm satisfied.

op- call me for the flo pro stuff. i'll hook you up !

as for diamond eye, as cody said , is nothing but a problem. you get what you pay for !

Just ordered last week from Mike. I got a flo pro dual 4" SS no muffler coming. From what I've researched its the best bang for your buck. Also if u go straight pipe they will all pretty much sound the same. The 5" will be slightly deeper but brand to brand with no muffler will all be very similar sounding.

Flo-Pro dual 5" is what I went with.

I know lots of trucks with 5" flo pro kits and those guys are very happy with their choice in exhaust

While it's not a direct comparison, the diamond eye on my '06 Cummins was terrible. Now the flo-pro on my '15 psd was excellent. I will go flo-pro on everything I have as long as they offer it!

I have 5" Flo Pro and fit is good, like the sound of 5" too. I have Diamond Eye on my son's Nissan Titan, 3.5" dual exhaust and it went on pretty good considering the factory only made room for single exhaust and 2" pipe. Sound is very unique and very good. Don't know about their diesel stuff though.
