Installation was straight forward and the included instructions were spot on. Hardest part was taking the old system off. Those muffler hangers are buried on top of those cans!

I did the install in the garage on jackstands by myself in about 90 minutes, and I am no mechanic.

If anyone is thinking about a new exhaust. Make the time and effort to do it yourself. Great feeling of accomplishment once you are done.

I really like the sound. Has a nice rumble to it without being crazy loud. Inside the car you can certainly notice the difference, but none of the dreaded drone.

Here is a short video of how it sounds.

NICE!!!! Glad to see more of these hitting the streets. I don't think many people even know that Doug Thorley makes a Catback. We've been "quietly" selling them for about a year now. Excellent unit, stainless steel, x pipe, badass tips, incredible value for sure! Thanks for posting the video!!

I'm surprised that our price points are as low as they are with them too. They are nice and have a really good low, deep sound. Thank you as well for picking one up!
