Charlies exhaust had some issues with bends and exhaust leaks. So maybe a few more hp can be gained. Like charlie said, once the manufactured pieces come out they will be able to release more info on it. Trust me its well worth the wait. It sounds 10x better with the downpipes and primary cat removed. There was so much unnesesary bends in the stock dp / cats it was ridiculous. Much more throatier and makes your stock / aftermarket exhaust come to life.

Charlie, where do you get your car dyno'd? I've been wanting to get my car dyno'ed but don't know where to go. I want to get a dyno done on my car for baseline. Then get others done after RISS with stock exhaust, then with TurboTuner. Does it take time for the ECU to adjust to the new flow?

I think 500 crank hp is a little optimistic since driveline loss is static, but definitely mid 400s, depending on what the final rwhp # comes out to be. Important thing is 400+rwhp is doable with nothing but bolt ons. Easy to revert back to stock, so great for even someone who leases.
