Well worth the money
This was the easiest installation I've had for exhaust in a long time, maybe ever. Fit great, came with needed hardware and gaskets, not terribly loud, and looks almost factory.

2015 Civic Si Sedan
I ordered this for a 2015 Civic Si Sedan. It fits like a glove and the sound is amazing. The quality of the exhaust is insane compared to the stock one that came with my Si. Sound is there but its not an obnoxious ricer sound, the best way i could describe it is that its deep throaty groan that will literally put a smile on your face as your brain translates it to pure performance. I do not have a single regret ordering this exhaust.
