Anybody tried a STOCK duramax muffler on an NA or Blower app?
Im about to give up on finding a stock 6.2 exhaust and I can find stock dmax mufflers all day long everywhere. Has anyone tried one? Im plan on running it with lts and no cats, just want to make sure its not going to sound like ***. It will probably be a month or two before I try at the rate I move but in the mean-time Ill probably go ahead and pick one up if someone has some sound clips.

I have a gauge for that

Thats exactly what I wanted, and I read about the donaldson's last night. The only thing ive read is they sound like stock on the inside and you only know its not stock when you drive next to a wall or something. I figured being a 5" muffler it wont be any kind of restriction, even though it has some sort of cone baffle in the front.

There's a guy in my town that has a pretty bad VHO truck with stall, cam & bolt ons,125 shot, headers, not sure on ory pipe or not but he runs a flowmaster made for a duramax & his truck sounds good. I say go for it.

I had a stock duramax exhaust on my 2004 5.3 ECSB when it was N/A and Turbo. 2 different ones actually.
N/A I didn't care for it because it droned. I had 4.10s at the time so I was running higher RPMs on the higway. Sound was nice, you got a growl on start-up and it was a little louder overall. It exited at the stock location. It was kinda inconclusive because I later took it off and noticed the exhaust shop left a 1/4" hole in the weld. I threw it away and went back stock.
For my turbo, I tried a different one and I loved it. It sounded awesome at startup, maybe even a little loud. On cruising, it was perfectly quiet. I can't stress this enough. It was even dumped after the axle. I had 3.23s with this one. I took this one to the scrap yard when I took the turbo off.
The first catback had no flange, the second one had a 4-bolt flange that bolted up to some kind of catalytic converter.

I guess Ill wait and see what the stock catback sounds like with the lts/ory before I jump off the deep end. I can find stock duramax exhaust pretty easily it seems so Im sure Ill be able to find one easy if need be. Im a fan of the stock exhaust look, my truck looks totally stock except for the TA diff cover. Ought to be a nice sleeper once I finally get the blower on. Hopefully someone has ran one NA with no weld problems, I do not want drone at all. My axles have 185K on them so within the next year or so Im going to pull those and refresh them but go back with 4.10s so Ill be turning some RPM on the highway but only slightly more than regular 3.73 setups since by that time Ill be running a little taller MT tire.
