Generally speaking, I've always heard that reducing backpressure tends to give more peak horsepower, but also tends to move the torque peak up in the power band...good for all out performance, but not necessarily so great for "around town" driving. This curve is actually better at the lower RPMs than I would have expected.

WHY ARE THE DYNO RESULTS SO VARIED?!
how come in the regional forum for ca the san diego dyno run with a stock 8 produced a 191 hp and this one with a modified 8 provided 180? I'm confused is the info on this site tainted or is there really that big a difference between locations, cause I'm not doin squat to mine if it's faster in San Diego than it is elsewhere.... which I don't believe.

Wonder if Borla is going to offer a non-cat back version. In Florida you do not have to have a catalitic converter unlike other states. So by just taking off the convert I'll get another 10hp.

A tiny bit of info on the Borla Exhaust
Socalmotorsports had an ad on eBay for the new RX8 Borla Exhaust, so I sent them an e-mail asking if they had a sound clip. They don't, but here is their response:
We do not have this on video clip, as they are coming in from Borla in a couple of days. But from the buzz I have heard coming from Borla and others this is one sweet system. Don't be expecting a loud sloppy flowmaster sound. Think more of a classic deep deep rumble that really lets loose at around 3000RPM'S.
With this system you get power and the perfect sound to accent your already highly advanced RX8.
Let us know what you think and maybe we can set something up so you can save some big $$$$$.
Thanks again for your time and interest in our products.

It will not void the warranty on anything other than the stock exhaust unless Mazda can prove that the Borla exhaust directly caused a problem with something else.
Dyno information is in this thread.

Damn people, I gave you a link, click it!!!

They're calling it a 10hp gain but have seen up to 15. Not much of a torque gain though....

I'll wait thankyou
I'm in no hurry. I waited 3 yrs before I swapped out my stock exhaust for Corsa Indy pipes on the Vette. I'll wait until I hear somebody else's RX-8 before I make any decision on spending the $. Also, I kind of like having the stealth quiet stock exhaust.
Besides...I think an ECU reprogrammer would get better bang for the buck once they come around....

you know thats one the most truthfull, most hope-reviving things i have read in this forum in a lonnnng time.
besides of anything else that may come out for it, this will be one handy tool (lets hope its well under $1,000 for your sakes) anything else is too early and those hp gains from the catback, dyno slips please from more than one real time owner with this mod made til then those 10-15 hp claims are vulgar!! just as any other claims made w/o proofs..
edit: i ment to say dynos from people like you and me that may have this product (as mass produced)
