Best Sound Available for 5.3

Reviewed By david r (Summerville, SC) Reviewed for a 2016 GMC Sierra —9/13/2016 4:52 PM

If you're like me, at this point you've listened to every exhaust video on YouTube. The price on this one was my only hesitation, but having it on and seeing how good the black tips look made it all worth it! Oh yeah, the sound...Amazing! I've had a 5.3 with Flowmaster 40 series, so I'm very familiar with drone. This exhaust has none. The 40 hp is just a bonus (joke). Power increase? Not sure, but it sure sounds faster. rebate=you'll need upc off the box.

Dynatech SuperMAXX Complete Header Exhaust Systems Reviews

Great sound and power!!

Reviewed By William G (Phoenix, AZ) Reviewed for a 2002 GMC Sierra —10/8/2008 10:15 PM

The install went very smooth for a set of long tube headers. I just had to fight my previous custom cat-back to fit length wise. (the cat-back system is pushed back 1-2 inches) The increase in mid-range torque and throttle response is noticable; even pulling harder in the high rpm range. After the system went through a heat cycle it has a very nice golden tint. The only down side was that I had to cut/splice my o2 sensor wires to lengthen them. The one supplied in the kit from dynatech was incorrect and the directions showed two possible connectors and how to modify, but the connector on my vehicle was neither of these. One of the passenger primary tubes is very close to the frame if not touching it at times under vibration and rotaional torque. But, overall I am very satisfied with the results!
