Really happy I got this. Cost of part plus professional welded installation was far less than the slip on kits. Glad I got the 14” rather than 18” - I wanted my truck to sound a bit more aggressive without pissing off my neighbors. It indeed has a nice low rumble but isn’t that loud or obnoxious. I hear a bit of drone in the cab when accelerating or otherwise pushing the engine, but hear hardly anything when cruising. I was a little nervous the 14” would be too loud, but it’s perfect. I have 2014 Ram 1500 hemi crew cab with single pipe.

muffler was excellent and delivered completely new and undamaged. Muffler gives a nice deep engine idle that is noticeably louder than stock. not quite as loud as flowmaster idle, but still noticeable. the engine revs nicely. However, do not buy this if you have a GM chevy or gmc V8 truck because the drone is absolutely UNBEARABLE. Your better off getting a flowmaster 40 or 50 because they will drone less. This muffler was excellent on my f 150 with 4.6 v8 (which had minimal drone when equipped)

Vehicle: 2001 GMC Sierra 4.8L V8. 3.73 rear end ratio

Bought a flowmaster 40 series for my sierra a while back and couldn't stand the highway drone that it made on the interstate. Took it off and put the factory back on.

I decided to try an aftermarket muffler again but this time a magnaflow since they use a different technology than flowmaster. I rode in a friends 4.8L silverado with the #12259 (18inch) magnaflow muffler and although there was no drone, it was very quite and not much louder than stock. I decided to get this 12229 (14inch) model because its a little bit louder than the 18inch. Bad mistake, highway drone is still there not as bad as the flowmaster form what I remember but still bad enough. On the plus side it sounds wicked around town especially between 2000 and 3000 RPMs. I ended up putting the stock muffler back on (again) and selling this on craigslist for like $50. Lesson learned: either get a real catback exhaust system or don't mess with exhaust at all. Trying to go the cheap route with just a muffler sway isn't worth it.

Installed this on a 2012 silverado ltz 5.3
This muffler has impressed me. Is pretty quiet at idle which is what i was after as to not annoy neighbors or wake the family while warming up my truck for work in cold months with my odd work hours. But yet great sound while during accel. It reainates a bit more in the cab then i expected with as quiet as it is but its nothing overwhelming that cant be toned out with some music. Great all around sound. I wont ever go back to flowmaster mufflers after this experience.

I put this on my truck with 500 miles on it. I was a little reluctant about removing the factory muffler with it being brand new. Well, not anymore. This thing sounds great. I was torn between a 18 and 14 inch model. I'm very glad I didn't go with the 18. This is not to loud and has a nice low growl, with very little highways drone. I have 5000 miles now and it still sounds great. Get one.

Had this installed on my 2014 ram tradesman hemi, but I kept the factory resonator. It's got a nice rumble, but it isn't so loud you get annoyed. I highly suggest getting one of these if you've got a v8. Not sure how they sound with other engines though.
