K&N 77 Series Metal Intake Kit Reviews


New Life

Reviewed By Chad H (Timnath, CO) Reviewed for a 2003 GMC Sierra —4/7/2014 5:17 AM

I should have installed this product a long time ago. Trucks sounds better, runs better and has made a improvement in fuel mileage. The most noticible is the sound of the turbo, in the past a new stock filter would allow turbo sound to be heard for about a day then it was gone. You feel more connected to your truck when you can hear what it is doing. At the same time it's not so loud that it becomes annoying or obnoxious to neighbors.

Flowmaster: the awesome exhaust experience

Reviewed By william m (new castle, DE) Reviewed for a 2003 GMC Sierra —9/24/2013 8:38 AM

Delivers the sound I wanted; not obnoxious, a sweet rumble at idle and a very mellow reminder at cruising speeds. I would heartily recommend this cat-back system. It bolted up just as described and offers a great looking finish with the chrome tips. Be advised you probably will need to purchase exhaust hangars because the ones you have will be difficult to re-use and/or are aged.
