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.
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.
