I've searched around and the RX-7 people seem to think the Dynomax Race is a good muffler for the rotary. There is basically nothing on RX8Club.com except whole exhaust system info. I'm looking at replacing just the muffler on my RX-8 and was wondering if anyone has used the DynoMax Ultra Flo Welded Universal Muffler? I want a fairly quite mellow sounding muffler, but have no clue what most acceptable piston engine mufflers would sound like when put on a rotary. Any help would be greatly appreciated.

Might seem a little expensive, but their exhaust systems are the end all, in my opinion.

I got the Borla catback system. Best price and very close in design to the dynomax muffler systems. dynomax mufflers is what PFS used. They sounds awesome on rotarys.

I think it makes your car sound like a U.F.O.

I have a friend who has the Racing Beat on his 8. It sounds good, if that's what you're after. Don't look for any hp gains. Read the info on Racing Beat's website about their tests on their exhaust system and their competitors'.

That's part of the reason I'm not willing to spend $500+ on an exhaust system. I just want it a tad louder and I can swap the muffler for less then $150. And it can't hurt to save a few pounds in the process.

Tell me about THAT! My stock miata muffler weighed like 15 lbs heavier than the stainless Borla muffler I put on it.
