Great Product!
I just installed this exhaust on my 04 RX-8 and I absolutely love the sound! The exhaust took a lot longer to arrive than it should have, but, it was definitely worth the wait.

Best Value For Your Money
This exhaust is perfect if you are looking to customize your tC! It's not excessively loud and is far from quiet. Installation is very simple and can be done with floor jacks; remove 6 bolts or so, put this exhaust in its place, bolt back on and go. Once you start the car, you immediately hear the roar of this exhaust. It sounds awesome at start-up, rev it up and you'll love it even more. Power gain is there, but it's not substantial. It's also important to note that I tried the TRD axel-back exhaust before buying this one...what a waste! There was no power gain at all and the only way you heard any sound from the TRD exhaust was from revving while in park or neutral, regardless of how fast you went on the highway you wouldn't hear much. With the Agency Power Exhaust, you hear the exhaust inside and out of the car. You can hear when revving in park/neutral and can hear it when accelerating on the highway. The craziest part?? TRD exhaust: $525, Agency Power Exhaust: $600. Agency Power while not yet a household name (that I'm aware), is a significantly better deal. And to be honest, there are not alot of catback exhausts for the 2013 tC; this one seems to have the best sound and price. Hope this helps. P.S. Agency Power made their own demo video of the exhaust that is available to view on Youtube if you're interested.
