If your not trying to be obnoxiously loud then I recommend getting this exhaust for your 8th gen. Still sounds like stock with a deeper tone that's not annoying or attention grabber unless your cracking vtec lol im currently running 3.5 berk hi flow cat with this exhaust and vtec crossover sounds amazing I would definitely get this if your in the market for a new exhaust

Exhaust has a deep sound to it. Not raspy like those cheap brands. Fitment was perfect. If you were thinking about buying this and had your doubts, do yourself a favor and pull the trigger. You won't be disappointed.

To summarize what I think of this exhaust, paired with a high flow short ram intake, my Honda is the opposite of ricey. She sounds aggressive and breaths a lot better than stock! Glad I bought this brand!
