Greddy:Greddy claims a 22HP increase over stock for this.
B&B:Vivid Racing claims a 19 HP increase over stock.
Price is about the Same.The gain is very interesting in horsepower.I think that both systems are not street-legal???Please vote because i need some opinions.The sound from both the systems are.....excellent.

 

these two exhaust have both been discussed in depth, just do a search for both of them.

 

I will say that i think the Billy Boat is a little bit ricey, at leat with the midpipe. The greddy seems a little throatier

 

I ordered the greddy about a month ago, and should be getting it in next week (backorder sux), but I think it will be worth the wait. I will let you know how it is as soon as I get it on. If you haven't already ordered one yet.

 

Too bad neither wasn't a choice.

Racing Beat or Borla.

 

Mazdaspeed !!!




However, between the two... Greddy.

 

Borla or Racing Beat...

 

Racing Beat???? what is the review in this one???

 

I'd go for the Greddy Exhaust. I found out from the dealer I'm dealing with that Greddy exhaust for the RX8 is on national backorder, but like somebody replied to this question/thread, it'll be worth the wait. I even have the Greddy exhaust emblem installed already(to cover the previous dealer sticker they put on my car and it turned out to be good cover up, didn't have any scratch or anything but just thought I'm putting a greddy exhaust anyway)

 

I enjoy my greddy a lot, but the only way yer making any HP off it is by using a midpipe. Standard catback exhaust doesnt do anything for HP. It's louder and a little lighter, but thats it.

And BTW, build quality fo the greddy is excellent. I havent seen any BB pics to comment though.

 

Were can I buy a geddy exhaust kit

 

No where. Especially not with that bump.
