Flowmaster Exhaust for GMC Yukon

I just had my new Flowmaster Exhaust installed last week. The sound is great and give my Yukon that little extra to take it from stock. I had the same Flowmaster Exhaust previously and love the sound. Unfortunately they only last a few years in my experience so you have to keep buying them.

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.

Well made and the tone of the exhaust is not excessive, it sounds good and fit tightly but correctly.

it was a very good set of pipes very reasonably priced i was able to do it myself in a matter of hours and it wasn't terribly complicated the only thing that i was a little confused about was the pipes don't come out very even one was higher than the other i think the hanger was too small. but awesome sounds pretty mellow then you get on it and your car comes alive! not bad performance i have it along side a hypertech and kn intake

Receive shipment on the day it was promised. The installation was very easy and straightforward. Almost no resonance in the interior at hightway speeds, even when towing a boat. The clamps supplied could be a bit more robust. Definitely should weld the system after installation to cut down on rattles.

Very nice looking easy to install and very fast delivery. I was looking for sum kind of loud,American thunder was rated as their loudest system. So I was hoping to get a loud rumble the tone is not bad I like it. Not as loud as I thought it would be but nice tone/rumble when I gas it. Performance I did notice my truck a bit faster or responsive when passing nothing documented mpg not sure I need to drive it more often. Over all its a nice upgrade from stock but if ur looking for sum loud then this isn't for you.
