What companies/vendors make aftermarket mufflers, exhaust system, and/or intakes? I know Racing Beat is one, but are there any others?

 

dynomax pacesetter are some exaust setups ive seen ive even seen flowmaster exhaust on an rx7 as for intakes lowes sells a good cold air intake for fbs! lol

 

Racing beat is the only name you need to know for exhaust.

 

Danke, all for your help.

 

I was looking at the Rotary Performance system for high flow cat and downpipe.

Then a RB power pulse muffler.

 

Kickryde makes a killer exhaust set-up!

 

hmmmm, the RB system isnt going to be suitable for everyone. Bridgeports, turbo 12a's, and I'm assuming there's some sp setup's that would require less restriction than the rb systems. I have talked to a few people who have said that the magnaflow stainless steel mufflers do a good job on rotaries. check out www.bigexhaust.com, they seem to have good prices. just my thoughts...

 

Sweet. Thanks for the ideas. I'll check em all out.

 

Oh yeah... I heard that Monza makes mufflers for rotaries too. Any thoughts on that.... feel free...

 

i got one......

 

Hey, what model does the flowmaster make that works for 1st gens? They aren't very specific on their website, as in "small or import enjines, 4-6 displacement". Anyone happen to know a good model that they make that'll work for me?

 

Haha... ok, so you don't like the idea of monza. What is it? Bad sound, or no improvement in power? Or both?

 

Rx7.com & RB use the same muffler I've had one of each on my two cars... Great muffler either way..
(My Rx7.com high flow worked great too)

Monza sucks. I had to replace my Monza cat-back system from Victoria british in just over a year because it was already starting to rust, and no longer did an acceptable job of "muffling" it had worked it's way louder and louder and louder until I finally replaced it.

I've head better things about their headers. (monza=pacesetter BTW) you just may want to take a littel bit of extra time to grind out some of the welding slag at the entrance to the pipes for a little better flow. My friend used one for ~3 years on his 12a with no issues..

Also check out mindtrain exhaust. No personal experiance, but plenty of good reccomendations.

 

OK. My friend has an eclipse and said that monza is awsome, but I don't think he really has much hands on experience with rotaries. Also, why is it a generally accpeted idea that louder is NOT better? i tend to diagree. that is... until i get pulled over, but seriously... the noise doesn't change the effect of the muffler on the enjine, so does it really matter, or do most of your comments refect personal preference?

 

I'm probly gonna go with RB, but flowmaster looks pretty good as well. The only thing is that I don't know which one will add the most power. I'll probably get the muffler first, then once I get some more money I'll install it with the whole catalytic converter. I want to maybe get a rebuild next year too. That'll add some hp I hope.

 

louder is not better, up until a week ago i had one muffler coming off of straight 2.25 piping from the rb header. good power, ******* LOUD. now i had a chambered muffler welded right after the header. 100% quieter, awesome deep tone, and no loss of high end power but a huge gain in low end response!!! louder doesnt mean better by far. a good muffler has high flow capability added with good muffling. hence....."muffle-r"

 

yeah - fer some reason the fart-can crowd seems to equate mufflers and resonators...

 

Many of the aftermarket "riceboy" mufflers actually flow worse than the stock ones. They may be straight through but on some there are louvers that project into the airflow to catch some of the air. May as well stick a brick in the tailpipe. It would flow better. These mufflers look like they flow alot due to their straight through design but airflow is very poor. Too much turbulence and area loss from the louvers. But they are loud! Others are too loud and require an insert in the ends to quiet them some. Think of these inserts as a cork with a hole drilled through it. Why would anyone do this? You put a free flowing muffler on then you plug up the end? Counter productive. They are loud too! There are many straight through mufflers that are loud and flow good. Dynomax Ultraflows and Brullen are 2 examples that come to mind. Some are louder than others. The Racing Beat mufflers flow really well and are fairly quiet but by no means are they the be all end all company when it comes to rotaries. Flowmaster themselves do not recommend the use of any of their mufflers on a rotary engine due to extremely high heat levels. There are also certain resonances at different rpm's from the rotaries that like to vibrate these mufflers apart. Baffled/chambers mufflers do not usually (not always) flow as good as a straight through. The exception to this rule is the Spintech muffler. It is very small, can be quiet or extremely loud depending on the model, has no packing to burn out, and is made entirely from heat resistant 304 stainless steel. Its flow numbers are extremely high. Do a little research, see what others use and like, find out what you are willing to pay and go from there. There are many great systems out there and many of them will probably be to your liking regardless of what style it is. If you have an n/a though don't expect any power miracles from just a muffler swap. You'll need a header to get a big gain. You'll get a little without one but don't expect the magic power genie to give you fast quarter mile times.

 

Thanks a ton for the info. As I've mentioned before, I'm new to understanding any enjine, much less rotaries.

Oh just for the record, I hope all of you know that I am NOT another one of those civic ****(pardon the coloquialism) looking for a real loud weedwhacker muffler to "impress" all the other guys. I am looking for a muffler that will add the most amount of hp when coupled with an intake and a catalytic converter.

Also, dumb Q.: when you refer to "header"........ that is... ??

 

header;


midpipe/cat replcement


muffler


system (droooolll...)

 

Ok cool. That's what I thought, just wasn't sure because everyone calls things different from their proper name, etc.

Yes, that's the system I will hopefully eventually get. I'll Be starting with just the muffler though. Unless you guys think that's a bad idea... heheh.

 

Check out the for sale section of this forum. Exhaust stuff is always being sold and bought, and the price is usually right (read: cheap)

Good luck and happy motoring!

 

I had a flow master on mine a few yaers back and it lasted like 6 months before it started rusting and sounding all funny on my, I think I burned it out

 

Save yourself the trouble of buying a new $250 Powerpulse muffler now and a cat repalcement, and then the rest or a full system later. One of the main reasons why the RB exhaust stuff is recommended is becuse it lasts forever. I have never seen a post by someone saying their RB exhaust was worn out. You should be able to find a nice used system for $300-500, better than the $750 for a new one including shipping. There is a guy in Washington that hwas two 13B setups. Another ad on the Parts TRader that has a header, cat replacement, and PP muffler.

If you don't have $300 to spend now, pick up a Maganflow stainless 5x8 oval muffler for about $115 at Bigexhaust linked earlier. It will be quiet, look good, and last on these rotaries.

 

My system: 2" primaries meeting at mid-drivers seat, 2.5" pipe through two resonators, mandrel bent over diff into a round bodied 2.5" Magnaflow. Non of this bolt on stuff..custom made is the only way to go (except the headers which I couldn't justify on a stock engine). I recommend the Magnaflow: not restrictive at all, decent (but not excellent) sound suppression, looks good too, and will not burst at seams like cheap mufflers. It has lasted two years and is not getting louder.
