In my endless quest to shut my n/a the hell up (used 3 different cat backs now). I have been recommended the 60 series flowmaster.



For those of you not familiar with this particular muffler it is designed especially for 4 and 6 cylinder motors. From what I have heard it takes the high pitched blattyness out of the exhaust tone, but rotary engines produce a lot more sound than any 4 or 6 cylinders, so I'm curious if anyone has experience with them??

that what i had on my 300zx and the sound was really deep. it was a really great exhaust on the z. i dont know about a rotary thought.

TURBO OR N/A 300Z?

Did you try Dynomax SuperTurbos?

mazdadrifter

nope, I've tried some straight through type mufflers running dual



corksport catback, and the moroso spiral flow mufflers. The spiral flow seems to shut it up the most, but this is my daily driver, and I'd prefer little to no attention.

Why don't you just stick with the stock exhaust? Also, don't they sell resenated piping, or unresenated? can't remember, but one is supposed to make the exhaust quieter. Flow master if probably gonig to be pretty loud, i had them on my camaro, you could hear me a 1/2 mile away

mazdadrifter

that'd be great, but I haven't had a stock exhaust in a couple years

I heard from a muffler guy once that a rotary would soud like a bi-plane, if you put a flowmaster on it..

according to flowmaster, the mufflers they sell will not hold up to the rotary's exhuast pulses, the welds break free rather quickly, like a matter of weeks (sorry, I don't remember who brought this up, but this has been discussed before) I hear that racing beat is good, that is what I will probably be putting on my car when/if I rebuild it in April.

I've heard the RB presilencer and a Borla XR-1 make a good combination. I'm running the old style black RB mufflers on my N/A. Sounds great.
