Flowmaster 74151 FlowFX Muffler 3.5" Center Inlet/Outlet - Moderate Sound 409 Stainless Steel

I'm running this on a 2012 6.2 denali. It sounds amazing. Just enough to where you can hear it. But not too much where the sound is obnoxious. Keep the resonator, delete the third cat, and you have a very tasteful sound. Even none car people have complimented it. The box looks like it survive world war II. I dont know what it went through in shipping. the muffler itself had a couple small dents but I didn't mind. It was still usable

Installed it on my 2016 Silverado 1500 LT. Exactly the right amount of sound i was looking for. Really good aggressive but not overwhealming sound.

Great quality.. But with long tube headers on my 6.0 gas Silverado.. it's loooouddd... Bad drone.. sounds good. But not a good choice for daily or tow rig.

Exactly what I needed for a decent, none obnoxious noisy as heck straight through full flow exhaust on my 2006 6.0 gas Silverado. Replaced my sorry use of a glasspack that still sounded like it was straight piped. Completely took away the ear drum bursting drone and now sounds much quieter inside the cabin. Love it!

Nice start up tone when cold and mellows out when warm. A decent drone but not obnoxious going down the road. Installation was easy and looks great under the truck. This is on a family HD truck for towing and hauling and I wanted something that wasn’t expensive and loud. Not in my 20’s anymore so loud noises do not appeal to myself or my family of 5. Thank you.

Takes a little of the raspiness away, I installed it at the end of my exhaust pipe. A lot quieter at idle, still very loud at WOT.

I was looking for the right sound for my truck and this is exactly what I was looking for!

I had a lot of work done to my 2002 Chevy 2500HD 6.6 Turbo diesel. IE: new injectors, pressure lines ,Head gaskets, water pump radiator rear brakes and a new bearing. While it was being worked on I told them to loose the muffler, they did, it ran a lot better but, it also made way tooo much noise. Now I have a flow master straight through fiberglass packed muffler, still gives me a growl but not a nasty sound,

Fit properly onto my 2005 GMC sierra 2500HD Duramax Deisel. Added a bit of noise but wasn’t quite as much as I had hoped. You can hardly hear it from inside the truck but You can hear it more when you’re an onlooker while the truck hits max boost and roars a bit

Recommandé pour votre 6,2 gmc!!

Not bad muffler. Fit my 6.2L silverado and it sounds pretty good. A little on the quieter side but still puts out that beefy V8 sound which was a step up on the stock muffler. 4 stars because the box arrived smashed up, muffler seemed ok though

Good quality muffler for the money pretty loud on my truck but has a good rumble and drone in the cab is tolerable much better the the mbrp muffler that I replaced with this flow fx
