Magnaflow Street Series Dual Exhaust System with Polished Tips; Rear Exit (11-19 6.0L Sierra 3500 HD)Find parts that fit my vehicle

Vrooom! With Authority

I was leery about scratch and dent on an exhaust unit. But man! I choose well! I had to snip a TAD off of 1 end that attached direct to the muffler and done! Beautiful fit and finish and equally loving the deep, tame rumble this beautiful Magnaflow exhaust added to my 2022 5.7 Hemi!

Decent sound

It sounds very decent. Little quite at idling but when giving it gas she has a nice rumble. Only negative thing is the pipes weren’t lettered like instructions. You don’t need 14.5 extension for any Colorado. But instructions say you do go for crew cabs. Must only mean full-size trucks.

Great sound when you get on it!

I installed this on a 2024 Lariate Antimatter Blue with the Chrome package and it looks like original equipment but with a roar when you put your foot into the gas on this V8 Coyote motor. Sounds great!

Magnaflow Street Series

Well made, relatively easy to install. Looks great is quiet except at open throttle, then only mildly loud. Suggest wiping entire system with windex prior to running engine. Also, use anti-seize in joints to facilitate removal/adjustment. Requires removal of spare tire.

New Sound

Stock is quiet and boring, and the new exhaust sounds great (man truck sound)

Magnaflow Exhaust

Easy to install and fit very well. It was quite a bit louder than what I wanted so I cut the muffler out and replaced it with a flowmaster series 70. Now it looks good and sounds much better. I'm running a stage 2 Whipple so I really cant say if the exhaust helped the performance any. Just looks better than the stock pipe hanging out the back

Stainless dual pipe exhaust

Easy to install, performance looks, fuel mileage on freeway increased by 2.5 mpg, different sound.

Nice Low Rumble

This system is resonator back, just what I was wanted. Deep rumble no highway drone. Self installed, by a 70 year old on garage floor. Hardest part removing the old. Had to remove the resonator to rotate and unlock that bead in slot connection at outlet of resonator, re-installed resonator after the connection was released. 2 hours to remove old and 2 hours to install new. LOOKS & SOUNDS !

Headturner of an exhaust note

Cold start is fun to listen to.sounds calm and not to loud until you step on the gas,then it wakes up. I have it workin with a K&n cold air intake,the two work well together.

Dual exhaust

Removing the old exhaust was much more time consuming that expected, but that has nothing to do with this exhaust. For the most part the new exhaust went in pretty easily. One of the exhaust hangers was not bent correctly. Had to do several modifications to the hanger to drop the exhaust ~4" so that the exhaust would exit under the rear fender instead of through the rear fender. Sound is not as loud as I was expecting either. Overall, and after modifications the exhaust looks pretty good, just wish it was a tad louder.
