My stock exhaust finally died, seperated from the pipe. Wanted a deep throaty sound without it sounding like a can of pissed off bumblebees, considered Borla but after some research I decided on this exhaust. Glad I did. Has a good sound, drone is minimal at 3k which is cruising speed (interstate) to work and back i ccruise aroind 2600. What i can hear the radio drowns out. It's an axle back with stock from the down tube back. So have not really seen an increase in horsepower. Have not pushed yet either so cant really tell. No major change in gas mileage yet, have not ran a full tank yet. Installing was almost a breeze. Will have to get a gasket for it, does not come with one. Lube your old bolts and definitely replace. I broke one and had to drill it out. Not fun drilling out the bolt was the hardest part of install. Goes together quite easily. .

5 stars for sound not raspy, low growl with an cai. Quiet enough that Highway driving doesn't have a droning sound but still loud and aggressive when you push it. Didnt come with a doughnut gasket though. Installed with stock downpipe etc.

Absolutely love this product. For an axle back exhaust it sounds pretty awesome definitely would recommend if you don't want to spend a crazy amount on a full exhaust system.

Great looking and easy to install. I got it installed but haven't got to drive my 2013 civic si sedan. Will post another update soon
