Flowmaster Exhaust Systems Reviews


Great sounding exhaust

Reviewed By Jack D (Somerville, TN) Reviewed for a 2001 GMC Sierra —6/16/2015 5:59 AM

Flowmaster has always made great sounding exhaust. I had to remove an aftermarket hitch because the side brackets were too low and my son wanted the exhaust out the side. I found a factory hitch that fit with no problems. Other than that, which wasn't Flowmaster's fault, the exhaust install was very straight forward. We are very happy with the look and sound.

TonnoSport Tonneau Cover Reviews


Stepside Bed

Reviewed By Jason M (Spring, TX) Reviewed for a 2001 GMC Sierra —1/8/2015 2:30 AM

Fit was spot on when complete. Tight cover after adjustment and install wasn't bad by myself. The directions, while not 100% dumb proof are clear enough for average mech. know how to decipher. One point I would like to share about install that is not noted is make sure the side rails are mounted high enough for the bulkhead cross support to slide into rails. I have a bed liner that wraps over top of the bulkhead so I had to take that into consideration to ensure fit, but very good for price.

K&N 57 Series FIPK Air Intake (50-State Legal) Reviews


Good intake

Reviewed By Albert P (Biloxi, MS) Reviewed for a 2001 GMC Sierra —3/17/2014 8:15 PM

Took me a little over an hour to do, was fairly easy, just a tight squeeze mostly. There is noticeable throttle difference and I'm getting about 2 more miles to the gallon now. Worth the purchase
