Bro, that Dirtyminimax is not to loud and does not sound bad. It sounds great. I love it. I’d same I’m a new fan but I’ve owned them & loved the Duramax for a long time.

[@thompsona10625]

I would love to change out the DPF and all the associated crap under there and give her a little more noise but since the big crack down, the EPA shows up at your door, kicks your puppy, takes your birthday away, And fines you a million dollars at the slightest muttering of the words “delete”. I’m sure there’s still a way to do it but I haven’t gone down that rabbit hole yet. I’m with you on the “keeping the muffler”. I have an old deuce and a half which were all built with a straight pipe stack and a screaming whistler turbo which ejects its battle cry right over the passengers head. I had that truck a week before I put a big’o Donaldson muffler on it. A muffler gives it so much more “growl” than a raspy screeching out the back. Awesome truck!

[@matt13ross]

True story! And thanks!

A “turbo style” muffler tends to cut the drone and let the turbo noise pass through for the most part, I’ve done a few with the Dynomax 17698 and they sound pretty good, close to stock in the cab, nice on the outside. ✌️

[@matt13ross]

[@taylorh3930]

It sounds so much better straight piped! I'd go with 5" straight pipe exhaust myself.

[@matt13ross]

I don’t know of a 5” exhaust kit anyone makes. Or even a 4”

[@The_sinner_Jim_Whitney]

It’s not a 6.7 Cummins. 3” would be more than enough for that little engine.

I have a 6in on my 2012 lml. That's about the biggest you can go with tbh lol

[@jdp0316]

The exhaust break sounds good af

[@matt13ross]

I think so too

[@masterofThardus]

When it comes to 4 cylinder engines, diesel and gas and ESPECIALLY turbo, I think it's better to stick with intake mods so you can hear the deep intake note and turbo whistle. If you're gonna do exhaust mods at all, putting out enough money for a proper deep voiced but quiet exhaust is a must. No engine sounds all that great past a certain volume level, but 4 cylinders especially get worse as they get louder.

[@matt13ross]

Did you see my intake video?

[@robm3357]

Who did the tune? What kit? It’s unfortunate that today’s diesel has so much crap in the exhaust. There is a big percentage of HP lost in pushing the exhaust through the DOC and the DPF. And the soot that is pushed back into the EGR and intake manifold. But my concern is the warranty..... The forums are full of issues from EGR s plugged up to injector failure to holes in pistons to complete engines blowing up...... So I will wait till it’s out of warranty before deleting mine. Hope it lasts till it’s out of warranty,,, fingers crossed....

[@matt13ross]

My warranty is now gone lol we’ll see if it lasts. HD Diesel sells emission complaint and other tunes. Check them out.

[@AlpineSniper]

I have a 2019 ZR2 v6, is it worth trading for a diesel 2020? I really want a diesel kind of a bucket-list item. Great channel

[@ColdCircleX]

Are you ready to live with a diesel? It's not necessarily more difficult to own but it just needs a little more attention. Your v6 is faster and a well proven motor. It just depends on your needs. I would say if you ever move up to a full size I would look at the new 3.0 diesels.

[@matt13ross]

Thanks! I love diesels, and I’d pick it over the V6 for a few reasons: Fuel mileage It’s cooler IMO Sound Tuning options Turbo

[@matt13ross]

Solid points. I’d love to try out the new 3.0 in a ZR2 version of a Silverado. Would be a near perfect truck.

Mine has 4 inch pipe with Aeroturbine muffler and 6 inch tip. Sounds amazing and almost no drone. It's deeper than the 3 inch pipe and the tip makes a huge difference. Tried a 5 inch tip but it was a little louder and droned some

@@matt13ross aeroturbine makes one hell of a muffler/resonator. I have a 5” “5050xl” on my 21’ Cummins and it cuts down on the rumble at idle and the screech of the vgt turbo at warmup. Sounds clean down low, but sill has a nice bark when you get into the throttle. Zero drone on the highway and inside the cab it still sounds quiet like stock (unless the windows are down!). It even increases airflow so it’s actually a hp gain, proven on a dyno. I’d highly recommend it.
