What about ones that you can reattach the original chrome tips. I don't think I could part with the only chrome on my car.

why is racing beat the only way to go?

I'm curious also...I have the the complete RB exhaust on my SE...I like it...but I might want to change it...anyone have any other opinions on some mufflers...?

racing beat is designed specifically for rotary, all others will be very loud and some might not last either because our engines are notlike others, racingbeat sound the best imo, I have the system on my fb, now if oyu want something really loud than go with another company.

YnOhTnANaYrB

That is true...the heat will damage the mufflers...Guess I'm keeping to RB...! haha

The typical straight through 3" or 4" tip muffler is usually not robust enough to muffle the noise and does not hold up well to the hotter exhaust temps from the rotary. As an aside, if your system is already choked down with 2.5" or so pipes, a 3" muffler won't help much if at all other than the maybe the exhaust note.

The Racing Beat muffler by itself is probably the best for a typical street application. It is well engineered, and high quality.

The Racing Beat system (header, pipes, resonator, muffler) is well designed and appropriate for the car for most street purposes. The system does a nice job of quieting the noise, improving the exhaust note, and increasing performance, but does have two weak points:

- The resonators are too restrictive. They go down to 1.5" or so rather than maintain the 2" ID of the rest of the pipes.

- The bends over the axle and the combining of the two pipes into one are also restrictive.

Having said that, I have not seen a complete, commercially availble system that improves upon the RB system. So, for the typical buyer, the RB system is typically the best around. I have one on my car. If I were to improve upon it, I would look for larger ID resonators that hold up to the rotary's heat, and run under the axle to two separate mufflers, again ones that would hold up. For me, the price of reduced ground clearance would be worth the reward of increased performance.

I have typically run a no resonator, under the axle setup on my race cars.

like said in a previous post, rb system is the ONLY system, especially if u live where noise is an issue.

i'm also wondering about trying to find a alternative to the power pulse muffler. not all of us want to spend $230 on just the catback alone.

i think i'm going to try one of the cheapo ebay mufflers and see how she goes, i know it will be loud but anythings better than the totally dead muffler i have now...

main reason it is the ONLY way to go: racing beat specifically designs their whole exhaust system to allow for the extreme temps that a rotary engine produces, which is significantly more than that of a piston engine. This will allow more longevity in the use of your entire exhaust system. On top of being designed and tested for a rotary engine, i love the tone of the racing beat system...juuuuuuust right

I have 2.25 Stainless pipe, and a Stainless muffler on my car (PowerTech brand). Sounds a little loud under moderate throttle, but open it up, and it makes a nice growl. A little loud at highway speeds, inside the car, but not too bad.
The only thing that needs improvement, is a header. I cannot believe the previous owner went to the trouble of running a full Stainless exhaust, and left the factory manifold.

that's why your car isnt insanely loud yet. get that header on there and you'll be rethinking your exhaust.

Rogue_Wulff

LOL, already rethinking it. It was already on the car when I bought it.
Adding a header has crossed my mind, but I was afraid it would finish off what little hearing I have left. Do they really make one that much louder? I can see the noise level increasing from removing the cats, but just changing from a stock exhaust manifold, to a header. I wouldn't think it would make a huge noise difference.

bkm_rx7

lol...do they really make it that much louder??? HELL YES THEY DO! thats why racing beat runs a presilencer in their system my man.

This is so true. RB designed the exhaust specifically for the rotary and gives the best flow for power. Bigger isn't better. Its that size for a reason (someone commented on the pre-silencer size). The sound is phenomonial!!!! I got my long primary system back in the mid to late 80's and the exhaust has held up perfectly to this day. Not a single problem, no change in sound, and even the chrome tips are still chrome! I would recommed this exhast to everyone.

RB is the only way to go. I've seen so many other sys' out there. They rust and burn out in a few years. Don't buy any e-bay muffler. Stick to a rotary vendor who designed them for a rotary. I can vouch for the RB system; so I can recommend them. There are others out there, but RB is a trusted name.

with the stock manifold, both exhaust ports dumping into that one open area and exiting down one pipe, aids in muffling the sound. when u replace that with a header, u seperate the pulses into it's own individual pipe, increasing noise AND the actual sound the engine makes. that's why, without presilencers, u get that "tinny" sound that many on this forum don't particularly like. personally, i like it. that's what gives the rotary that distenctive soud that no other engine has. almost kinda like a 2 stroke dirt bike.

I've got the RB street port exhaust as well. It's amazing, still shines after a year and a half. The sound is awesome, and yet still retains that same "stock" look. It's not loud enough to become an annoyance to you while driving down the highway. The exhaust note is low. I wouldn't change it for anything.

candyassmiler

i like my magnaflow with dual 3 inch exits.

LaRazaUnida

now here is a question, what is better for a street ported car. The RB street exhaust(because of the street center pipe) or RB muffler/road race header and replace the street center pipe with a straight pipe?

bkm_rx7

hmmm...thats a good question. i would say that using the RB muffler with a road race header with a straight pipe would be better in that case. this is because with a streetport, you are gonna have more intake, which means you will have more exhaust, but this is just an opinion, i dont know that this is gonna be better in actuality. itd be nice if someone has tested this b4 could give us his/her opinion and/or results.

Short primary exhaust (one pre-silencer - collected header) for a stock engine.

Long primary (twin pre-silencers non collected header) for a street ported engine.

The pre-silencers don't reduce power, just sound for stock or street ported engines. Always keep them in. Things change for a Bridge port or P-port.

I'd contact RB if you have any further questions.

RB has a system they recommend for streetport engines. i know how loud they r with the roadrace header and stock muffler. i have yet to hear the same with the RB muffler. but i DO know that the sp exhaust system is very, very quiet.

Zyrano

since you brought that up, I already have a rb stock port header and a bonez cat, but i'm still running the stock muffler, is the rb unit going to be quieter? because it's pretty loud right now since i'm not running the presilcencer.

a header will make it WAY louder.
