2016 gmc sierra 5.3L

Reviewed By Jose G (PHARR, TX) Reviewed for a 2016 GMC Sierra —10/16/2017 9:59 AM

I gave the exhaust low marks on quality because you would think that paying that much for a catback you would get 304 SS but you get 439. To most that may not be a big deal but come on.... We are paying for the best. Also i expected a bit better fitment as the header pipe rests on the crossmember. The system has a good tone and drone on the intirrior is pretty much non existent, although don't take my word for it since i have 35" MT tires.

Great product

As always, the hardest part was was taking off the factory exhaust. The Gibson sounds mean but does have drone inside the cab. Very loud exhaust and I love it so far!

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!
