Hello all about a week ago, I installed my agency cat back. The exhaust is absolutely beautiful and Well built. First impression is that the car wakes up a little. Definitely feel a little extra something. I also have my secondary cats and resonator removed.
Only thing that concerns me is how quiet the exhaust is? At wide open throttle it's honestly as quiet as the stock exhaust? Did I miss something? The valves work and even holding them open its so quiet.

At idle and start up it's quieter than stock, from 1-3k rpms it sounds great but than quiets down after that? Anyone have had experience with something like this
