Ok first it was around 280 hp, then it went down to 250, and now Car & Driver has it listed at 247 hp. Originally it seamed feasible that it would be able to keep up with the 3rd gen rx-7, but now they are posting 1/4 mile times in the high 14's. This poor thing will lose to mustangs! The 350z is up there at 280 hp. What is Mazda thinking?

Maybe leetheslacker has a point. The 350Z doesnt gain much hp when a new exaust is put on.. think of replacing the entire exaust on a RX-8 and the gains it will have 
Mazda should tweak up the hp alittle more.. its gotta be able to sell! So it needs to beat rustangs..

Without a turbo version a exaust wont do much.
MazdaTrix even says on a N/A RX-7 a cat back exaust is only good for like 5hp.
Most tuning magazines will even say a exaust doesnt do much for performance on a N/A car, its more for looks and sound.
Mazda took away the strong periphial ports on the renesis so Im not sure how a aftermarket turbo would work either.

I read 247hp also, but I think they actually dynoed. If Mazda is saying 280, and road and track is saying 247, 33hp loss through the drive rain, is that possible??
I still think the Rx-8 is going to cream any other car in the price range once it hits the twisties. Straight line speed means little or nothing to me. Plus I think the gearing and were the rotary is making the power it will still kill a 350z.
About the exhaust, the number one place to make power on a n/a rotary is in the intake and exhaust. I would like to see the gains from a full exhaust on the new renesis.

If you mean to go so far as porting and what not yes, but a bolt on exaust is minimal gain on a N/A rotory, as well these b.s cold air intakes.
Only reason its such a great gain on lets say a otherwise stock TII is because it will let the car boost more.
