I don't know this for sure but my bet on the Jannetty testing it was with an ARH system that had high-flow cats vs one w/o cats. The difference between those two are probably minimal. However, the difference between the stock cats and high flow cats are probably totally different. My guess is that there is a chance of seeing some HP gain. The trick is going to be to get it to not throw a code and yet be resonably priced.
The ADM offroad downpipes (no cats) are supposed to be worth 18 rwhp but they need a tune. So....lets assume based on Jannetty's testing that if a high flow cat is about as effective as no cats then there is a chance you could see close to the same output as the ADM offroads. Again....get it to not throw a code and be reasonably priced and I'm in.
BTW: there was an exhaust Mfg (might have been Magnaflow) that did the same thing and showed it off at SEMA. The thing I didn't get with it is that they had two cats. You should only need one cat. Not only will the system be less expensive to produce but my guess would be more HP. I deleted my rear cat already and there are no codes or issues and it made my exhaust slightly louder. Only the first cat is being monitored by the system.
