how much more whp or hp can you get out of the greddy sp2 catback exhaust??

Not much. Do a search.

Maybe 2-3WHP

http://www.rx8club.com/showthread.php?t=16442 go a little way down the page and click on any of the exhaust to see what they claim to gain. search is your friend.

And by the way, there is a sticky above this post that tells you all about exhausts.

Nothing I can feel... I've had mine installed for over a month now. :)

thanks for all the input, have you guys also hear of greddy evott

I haven't seen any vendors selling the Evott for the RX8, but it looks like its already developed.

Someone had the Greddy Trust Titanium Exhaust on the forum here a while back, you can do a search on it. It should be a similar exhaust.
