Everything is sealing better and for the time-being, I did not need to use the RTV gasket. Hoping maybe the 109 deg summer heat is to blame for what feels like zero gain in power after the RHFC install.

It's a marginal gain un-tuned. When I added Test Pipes, I noticed the exhaust note change more than anything.

I did end up getting the UpRev Osiris tune through a local shop. And you're totally right, the tune solved this and woke the car up. Dyno graph and info can be found here:

I just bought rhfc off another member today. Can't wait to get it. Hope I won't have any issues. 300 club, here I come!

Just picked up my car. Short drive back but I feel like the sound is a little deeper and more gurgle/purr at low rpm. I really enjoy it.

About the install. It didn't fit right so they had to cut/weld on additional piping to create the length.
