2005GMC Yukon 4.8

Reviewed By Marcos R (Fresno, CA) Reviewed for a 2005 GMC Yukon —11/19/2016 12:46 PM

Bought for my Yukon, set up was easy, tough part was cutting off the stock muffler. Great sound fits my vehicle paired it with the K&N FIPK cold air intake have notice some pick up and go. Will definitely do more business with auto anything. Customer service was great. I received flowmaster in 2 days. Rebate on its way. Strongly recommend this.

Flow master 70 series

Reviewed By Jeffrey S (Warsaw, MO) Reviewed for a 2008 GMC Sierra —11/10/2016 3:22 AM

I purchased this muffler to replace a smaller flowmaster muffler that was too loud for my application. This has the performance of the flowmaster technology without all the noise.

What Did You Say?!

Reviewed By Joseph N (CLINTON, ME) Reviewed for a 2011 GMC Sierra —9/21/2016 8:13 PM

My ears are bleeding.... I love it. For real though, it's a little louder in the cab than I wanted, but I'm glad I didn't go with the Super 10. Good price, gotta love AutoAnything. Had it welded, only way you should do it really, and appearance I could care less about because no one is going to be looker underneath my truck.
