Don't know if it added any horses but definitely an improvement on sound.

My old exhaust on my 2003 Tahoe was falling apart. The Magnaflow was stainless steel and fit perfectly. Easy to install and sounds great. I am a happy customer! KGK in PA

Great all around exhaust for people that want a nice sounding exhaust but still want to hear after driving. Easy install. Only one draw back, pipe going over the rear axle came close to the body mount and would rattle every now and than. Just bent the last exhaust hanger down a little and solved that problem. Great low rumble and no drone on the highway. Great stainless steel quality, before i always had the cheaper material and would rust out after a couple of NY winters.

Great exhaust

Great exhaust for the money spent. Was easy to install and came with heavy duty clamps. It sounds awesome on my Tahoe and the tip has a nice rolled edge. The hardest part about the installation was removing the old exhaust!

You gotta get one of these

Yes, it drones a bit on the highway... but so what? It also roars in WOT, and I have already noticed an increase in HP just by the way my Tahoe drives. Autoanything delivered what I wanted, and they had the best price hands down. Two cuts with a sawzall and the OEM was on the ground. 20 minutes later the Magnaflow was on and rumbling. If I can keep my foot out of it for a while I might see some MPG gains! This exhaust looks, sounds, and performs great.

bad ass

I Put a single exhaust on my 2003 Chevy Tahoe and now it wastes gas as much as a car does!!! I love the overall sound that comes from MagnaFlow and have recommended it to everyone I know. I have searched around and could not find a better deal than from, Thank You for the great deal. Your satisfied customer Joe.

The is the best system I have ever owned. Gives a nice big block sound without being to loud inside the cab. Very nice mellow deep tone and quite on the freeway....until you throttle it. A Must have!
