Diamond Eye K4234A Cat-Back Exhaust System

Perfect exhaust tone in my opinion. I put this on my 06 dodge Cummins 5.9. Nice low rumble at idle and low rpms, when you step on it she sounds mean!! The muffler sounds better than strait pipe in my opinion, it takes the rasp out of it. No drone through the rpm’s. Install was a little tricky to do myself, would recommend a second set of hands to get everything lined up. Well worth the money!!

My truck is a quad cab with 8 foot box.The Diamond Eye exhaust system arrived on time. It is very well made and high quality. However try as I might, I was unable to get adequate clearance between the tail pipe and my spare tire. Ultimately I ended up shortening the length of the hanger rod for the rear most pipe clamp and that made everything fit perfectly.The exhaust note is similar to stock but seems a little louder at idle. The level of noise going down the highway is quieter than I expected whether under load or not.I also didn't notice much droning when pulling hard.Overall I am very happy with the exhaust system and highly recommend it. If it weren't for having to shorten the pipe clamp I would give it 5 stars.

I put this on my 2006 Ram 2500 5.9L Cummins. It's a perfect fit. It includes all clamps and mounting brackets necessary to install, which is great because mine were all rusted and had to be cut off. It's a cat-back exhaust meaning you keep your catalytic converter. I cut my original exhaust halfway between the cat and muffler. The pipe is long enough that you can leave the muffler off if you wanted to. Don't be lazy, do the work yourself like I did and save the additional $500 the shop would charge you...
