Anyone useing these?

I'd really like to hear one on an RX if possible. A friend of mine has opne on his honda and it's very quiet. I like it.

Any other quiet aftermarket mufflers out there shoot me a link.

Thanks...



Also has anyone heard of the spring loaded mufflers. They are quiet during cruise but as you get on it and exhaust pressure increases it unseats a valve or something that gives the exhaust a nice loud rumble?

 

does any one have a cut away of one of these things. i would like to see the internal design.

 

Never seen one of those. If the price is reasonable, buy it and try it out. I wonder how long the spring and valve would last though.

 

I had read about the spring loaded mufflers. I can't find them anywhere.

The one above is a mugen clone and I'm told is heavy as hell!

Anyone running these?

Local muffler shops want $80 farg'n dollars for an inline silencer. Figure I'd just buy a quieter muffler.

Do the silencers really quiet down these mufflers alot? I am looking for a muffler that is quiet. Not a fart can!


But if they are actually quiet I'm gonna buy one.

I talked ot the seller and they said they weigh roughly 5lbs? I don't see how that is possible either...

Thanks...

 

Links didn't work for me, but yes, a pre-silender will make a big difference. I have yet to see any muffler that will quiet down our exhaust by itself. If there was one, don't you think RB would be selling it? Get yourself a Magnaflow 14X9 oval or a Borla for a pre-silencer and be done with it. Sure it's expensive, but either is cheaper than RB and they will work better and last longer than any glasspack and most other mufflers.

 

Sorry here are some working links. These are the usual one chamber "fart can" mufflers U see everywhere. I never see them with the inserts in though. Find it hard to believe no one out in rx land is running one of these.

I suppose, I really didn't want to add 40lbs of muffler weight. Strange we can't find a way to quiet down these little buggers with a simple muffler. I'll work on something...

 

You could always just mount a big speaker and send out canceling sound waves. That would be amusing!


Hytech makes a muffler that is REALLY good. I have heard one of these on a integra, and it was near silent when crusing and had a nice tone when you jumped on it.




$400 though.

 

Has anyone tried an Areo Turbine muffler?
http://www.aeroexhaust.com/index.html

"When the incoming exhaust air stream enters the Aero Exhaust it is rapidly expanded and split via an airfoil cone with an orifice similar to a jet engine. The outer airflow velocity is increased due to the increased distance the outer air must travel. The higher density inner air stream also creates a low pressure vacuum in the outer expansion chamber that assists in drawing the air out of the exhaust pipe. The outer air stream accelerates as it recombines with the inner air stream. The recombining of the air streams muffles the exhaust sound and increases the exhaust flow. Thus allowing your engine to breathe easier and dramatically increases your vehicles performance."

 

You won't see the muflers in the links being used, because they are fart cans. When using the one with the insert, it kills power and sounds like ***. When the insert is removed, they sound worse and louder. The CF one is ricer gimmick junk.

 

Looks alot like this one for 55 bucks...

im running a muffler scimilar to these and i really like it. on a stock exhaust system the pitch is low and loud. i really like it. puts any civic to shame

 

The twin loop's are good cause they're straight through and loop through the muffler twice. So each one is like running 1.75 muffler in the space of 1 muffler. How eever they flow **** cause they have to huge loops to pass through. lot's of back pressure. If you're looking for a stock replacement that might give you a couple hp and some good sound go with one, but it's not the best for peak performance. All they are is a different design of an old skool dynomax superturbo turbo muffler. the only difference is that the bends are external. So for people who've been doing this a while you know that the twin loops sound good give you some hp, but are far from optimum. The Super turbo's are known for falling apart after a year or two on pissedons, so they'd last a few weeks of a rotary. I'd assume the external loops help eliminate that problem. As far as the turbine muffler. All that is is a louver'd core with a choke in it. It'll help quiet the exhaust at the expense of huge back pressure, and shitty flow and a loss of power.

 

I'm thinking of a a y pipe & dual exhaust with two 2 chamber magnaflows on the ends.

http://www.magnaflow.com/02product/s...ne=main&id=303

Or something like this...

 

dont use chambered mufflers, they kill flow.

EDIT: those arent chambered mufflers so nvm. but you wont be able to run the exhaust like that though, you cant put a muffler on the drivers side. take a look, it wont fit, and no way to pipe it.

 

Aren't the OEM mufflers chambered?

 

yes and they kill flow. The biggest gain so far for me is my exhaust.

Header>2.5" collector>4" round magnaflow>6" round magnaflow

 

There's no room to run a 2nd muffler on the driver's side due to the solid axle. It works on the 2nd gens with irs, but many of the 2nd gen turbo guys have gone to a big single exhaust.

 

run true duals all the way from an uncollected header into two four inch magnaflows, then cap it off with a dual in/dual out magnaflow at the back. it should flow well and sound amazing. i always wanted to do this, but my single 4 inch to dual outlet magnaflow will suffice for now.

 

anyway, i think if we got one of these and it was completely stainless, i think it would work. it would slighlty hinder the flow, and i think it might get hotter than a regulkar muffler being that the exhaust passes through it twice. but if it could handle it, i think it would work.

 

Let me introduce you to the guy that invented that muffler...

 

am i the only one who thinks the supertrapp designs are better for rotaries?

 

Seriously... Who has tried supertrapps on these cars ? I'm very familiar with boinger applications, but SA'a and FB's ?

 

ive seen it, there is a white wide body in indiana, i think aussiemg knows what im talking about.

 

seems like all the old wankel heads round these parts all use supertrapps. tunable back pressure is very nice, especially with carbs

 

Any sound clips? I would object to a super trap. Might have to wrap some stainless around it so it looks like one big pipe though. I think they look pretty odd.
