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

 

Not much. Do a search.

Maybe 2-3WHP

 

https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/rx-8-aftermarket-exhausts-summary-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.

 

Question
