Does anyone know for sure dyno proven or not, if the racingbeat dual catback exhaust for 2nd gen turbo's really adds 60hp? Thats what I've seen claimed... Are there better exhaust kits available?

 

WOW!! 60HP that would be crazy it its true... Is that the same for an RX-7 3rd GEN???

No, not the dual catback its the full turbo back race exhaust that claims the 60 hp on a TII. Doesn't sound outrageous to me. 3" off the turbo no catylitics and two low restriction mufflers. I bet the HP figures were for the 87,88 TII where boost will go way up due to too small of a wastegate. What is outrageous is that they sell this and claim only an FCD is needed to run w/ it. No way, at least get a high flow fuel pump and rewire if you run this, especially on the 87, 88 TIIs.
