  • You get what you pay for
I liked the fact that it matched the old pipe on my impala and that the hangers lined right up. I was a lil disappointed in the resonator, as in it’s not as quiet as I wanted and it changed the sound of my car. And I had to take off the burrs and do a lil rounding of the pipe ends so the coupler would go on. Where as the other spots it goes together were a lil too easy, and had to really crank down on the u-bolts to stop the air leaks. All in all, you get what you pay for ... show more

  • Could be better
Does not fit well on 2010 Chevy Impala. The space between the exhaust and the road is approximately 3 inches upon install. After approximately 2 weeks it was rubbing the pavement and caused the bolts to rip out leaving the exhaust on the road.

  • Resonator leaked from seam
I didn’t expect much for the price, but after I installed the exhaust I noticed the seam of the resonator leaked. It leaked about 3 inches of seam, I already installed the exhaust and wasn’t going through installing it again so I welded the 3 inches of leaking seam. I don’t think this system will last many years, but it will get by. There are better quality systems for a little more money. ... show more

  • Missing hardware and pipe didn’t fit
I purchased this for my 2007 Chevy impala it was missing hardware and one of the pipes was not flared enough to fit. I am having to purchase another exhaust clamp and have the pipe flared more.

  • Works extremely well!
I got this for my 2010 chevy impala. It showed up with a few dents but it but that was from shipping. My car is very quiet now. If you want a near silent car I would suggest this product!

  • POOR quality!!!
Pipe is bent wrong and not the correct size. It looks like someone tried to duplicate the original but did a very poor job.
