What exhaust on your deleted dmax?

brad6 · Jan 28, 2017

I'm looking to delete my 12 lml dmax in the near future. Anybody have any suggestions to run for exhaust with no drone and keeping it somewhat on the quiet side? I'm thinking 4". What brand did you go with and how loud is it? I would like it sound nice with out being that a-hole neighbour that leaves early every morning. Does anybody use the cat back system to cut down on the smell? Or most guys go down pipe back?? Or turbo back but I don't have plans to switch the dp.

Have MBRP and it has a drone at 100 km's /hr .
Well built but wouldn't recommend due to noice.
2012 Dmax

08 with mbrp 4" cat back. Has a nice rumble but not obnoxious when left idling outside on cold days.

Had mbrp on my 07 and it rusted out in a couple years and had to replace it with stainless one, 4'' and was alot noisier in cab, also no mileage change to offset cost of it.

I have an AFE Aluminized exhaust on my 06 duramax. No rust on it anywhere. The tip is a different story, supposedly stainless, if it is its a low grade because its pretty rusty with surface. Was thinking of painting the tip black.

My 4" exhaust, no cat, muffler, 3" downpipe, BD up pipes, EGR delete, and high flow y bridge is quiet at 100km/h, but at 110 it has a little drone, not anything i would complain about.

11 dmax Flopro, slight drone at 80km/hr but hardly notice. I would do again. Made in Red Deer. Overall exhaust is relatively quiet until you GT on the gas hard then she'll get everyone's attention.
Buddy had AFE, thought it sounded tingy.

removed cat and muffler,welded in pipe,same diamater as factory exhaust,dont notice sound in cab unless foot is to the floor,still not very loud unless windows are down and exhaust can ecko off a building or overpass,been like this for approx 6 years with no issues,07 duramax,very slight noise at 110kmh but most tires are louder

Flopro or Magnaflow. Fit and finish is so much better then MBRP.
And flopro is local...

I enjoy the flopro setup on my 12. no drone at all.

11 LML, test pipe clamped in that removes the dpf from loyd custom in Edmonton. Uses your stock exhaust as a straight pipe with no drone or excessive noise. Turbo whistles when you let off the throttle. Tuned with efilive hand held. Oil still golden after 7000km.

Merc, is the cat gone too with that set up you are running?

Merc63 · Jan 31, 2017

Ya the cat is built into the dpf, it's one huge tube.

Have a 4" mbrp on mine with no real complaints. Just louder than stock is my only complaint so far, we will see how it holds up over the next couple years.

Ran banks for 9 months. Two split mufflers later I said f it and went with mbrp. 12 years now on my 2nd mbrp. No issues. Support Canadian.

have a 5" DP back Flo-pro straight pipe on my 12' LML, sounds great and has a good bark. Bit of a drone but has never bothered me

A bark? On a '12? Odd. I haven't heard a dmax exhaust "bark" since the original LB7.

What exhaust on your deleted dmax?
