I bought my truck with stacks and I want them gone, yesterday! I'm looking at either a 4" or 5" stright pipe exhaust system and don't know what to get. I've had MBRP in the past and really liked it but that was on my old 6.0L Power Stroke (motor went bad, imagine that..) so I don't know how it would be with a Cummins. I'm not looking at breaking the bank either bc i know some systems can cost the amount of a 3rd world country. Any thoughts would be great.

I have the Banks 4" Monster SS exhaust w/muffler on mine and love it. Nice sound and No drone when towing. I've have Magnaflow before and would go def because of the drone.

i have the farm boys 5" turbo back straight pipe kit with a donaldson m090072 reasonator amd m090535 muffler. total os about $430 very easy to install.

when I first got my 03 few years ago I went to exhaust shop and did 4 inch turbo back. mostly just cutting the muffler off and putting in a 4inch pipe. since I know the guy and helped it cost me $50 bucks for material.. sounded really good but super loud.

then I got in trouble for being to loud. .87 decibals and legal limit is .80 decibals. so back to the exhaust shop and put a straight through maga-flo muffler on. doesn't restrict anything but the sound. got the same sound right at .80 decibals......

I have a 4" magnaflow turbo-back system on my truck. When not towing, it sounds good under heavy acceleration without being too much. Cruising in overdrive, it mellows out until about 80mph when the sound level picks up again. With our camper in tow, it is pretty wicked under acceleration. It will turn some heads in traffic. Towing in overdrive at 65-70mph, it is absolutely big-rig perfect. I could listen to it all day.

surfram

just installed a few weeks ago a mbrp 5" straight pipe turbo back on my 04.5. I always built exhaust by hand before so i was impressed with fit and quality. I love the deep rumble the 5" gives.

I just ordered a diamond eye dual turbo back I have heard lots about them and their fitment and I am very partial to the dual exhaust setups

I have a Corsa exhaust. It's pricey but has great fit, easy to install has absolutely no drone and has a straight through muffler. One of the things that led me to them was that it exited at the stock location and angle. I didn't like their gawdy oval tip and put on the old MBRP tip I had.

For the tubing, I went with a Diamond Eye 4" turbo back. For the $$ I was shocked at how good the fit/ finish was. For the muffler I went with a Banks. Nice and quiet with NO drone.
