what should i go for?

 

neither
search function exhaust is the best

 

05rex8, what body kit is that?

 

+1 on search function exhaust being the best... been using it for years now... sounds greatttt

 

search function body kit

lol couldn't resist...sorry
it's Tsunami, which is not being made anymore

 

Hahaaaaa

 

I would choose RB since they make a catback for series 2 and MS doesnt.

 

Lol, I bet he actually googled that. Well if you ever are thinking of getting rid of it hit me up!

 

I shall keep that in mind

 

Racing Beat if its between the two

 

Racing beat is a 3inch and I believe the MS is 2.5.

That is why I went with the RB.

G/L

 

RB!
Less expensive and slide right in. Perfect fit and finish.

 

RB FTW.
Especialy the twin tips.

 

Isnt MS 3.0?....if its 2.5 then I got a problem cause I ordered the RB midpipe and isn't that 3.0? Crap.. To answer your question...I bought mine with MS already on it and it's been great and sounds great.

 

come on....anyone know...?

 

Do you even know if you're asking in the right place? This is for S2 RX8s.

 

OP: I've gone 'round and 'round on this myself (to also include Borla) and have decided on a Racing Beat... with an RP SuperCat.

RB = superior build quality to the MazdaSpeed (welds) and it had the tone I was looking for. Hear them all in person before you decide tho'. Definitely an ear of the beholder item.

 

thanks everyone.

 

I definitely went with RB's you can check it out in my pics... sounds great sometimes i hear it over my subs too with the windows up. Pretty soon i'll be getting a midpipe and see how it sounds from there tho..

 

unless you some how found a boat load of power a 2.5" pipe is more than adequate for an NA street RX-8

 

Does air intake increases the power ??

 

^ the short answer is no. The K&N Typhoon produces some appreciable power, but at the expense of being very loud and it also doesn't work very well in hot ambient conditions as it ingests engine bay air. A cold air intake (CAI) will give you a relatively small increase and assures cooler intake air.

The stock intake and exhaust are already pretty much maxed out performance wise. Therefore, aftermarkets are more for unique sound. A high-flow Cat or midpipe on an exhaust do produce appreciable power. But again, fairly small when compared to a forced induction (FI) system.

 

anyone have pics of the RB twin tip catback on their car? Can't seem to find any pics of it other than the ones on the RB site...

 

Just ordered the single tip rb exhaust...can't wait to put it on next weekend.

 

Just got my racing beat exhaust in the mail...Sunday will be a good day.
