HEy guys... I know I will get SO FLAMED =), cuz not only am I going single on an N/A with ported motor but I also got the biggest ricest MUfller eva take a look... Is 18 inches long with out counting the inlet and 4 inch wide TIP!!!! It has a silencer that brings the output to 2.0 and the inlet is 3.0. I have a racing beat header and I already bought the RB presilencer getting it welded then adding an 18 inch magnaflow resonator to this muffler. It is a tanabe Racing medallion. Well enjoy the pics. FLAMES ARE WELCOME =)

when I see a muffler that big I always think the owner must be trying to compensate for having something really small in their pants

Hey, watch it.... some of use purchased our FCs with those contraptions stuck on there and would rather spend money fixing more important things. :P

HAHAHAHAHHAHAHAHAHHA you found my secret. You guys think ill be loud as hell? You think maybe ill get any back pressure?

trent1059 01-26-05 08:43 AM

purchase is one thing, buying the big muffler and actually putting it on your car is another..

1987RX7guy 01-26-05 08:47 AM

Oh come on dood...

PvillKnight7 01-26-05 09:19 AM

I used to have two Apex-i N1 mufflers, one on each side. It was abnoxiously loud cruising at 3k. My friends called them the water melon cannons and said I could smuggle mexicans in them. :)

oakback 01-26-05 09:23 AM

Keep is over your arm, and pretend to be Mega Man.

gergrx7 01-26-05 10:32 AM

rotary gonna be loud? haha i doubt it. with that muffler your car will sound like stock. well maybe not stock but "signature sound"




sorry dude its gonna be loud.

F1blueRx7 01-26-05 10:45 AM

Backpressure? This is not a honda. No backpressure required. When you get them welded on make sure you ask for the JDM Angle down so it looks REALLY terrible.

RRTEC 01-26-05 10:47 AM

Oh lighten up you rich bastards.... There is nothing wrong with a freaking "ricer" muffler....... I am not a fan of the single outlet, but different strokes for different folks... Here is my (god forbid) non-racing beat setup on my old 7....

Racingbeat header
Catco freeflow cat
Racing beat Y section
2- 4inch tip EFX N1 style mufflers

Oh, I'm not bashing huge tips, I have an Apex'i N1 Single... but at least it's "Rice done right".

Like jasmine rice instead of uncle bens. mmmm jasmine rice.

I thought that the 86-88 NA's needed backpressure to operate the 5th and 6th ports.

These are IYO the riceiest pipes I could have put on then. Hey I even got em angeled up and out. RB headers to a custom 2.5" mid pipe/y-pipe, to super cheap mufflers (unworthy of naming brand). Oh dont worry about them being loud, they will be. I've had a buddy of mine tell me that he can hear me at redline on the freeway late at night. His house is about 2-2.5 miles away. People know when Im exiting the freeway to go to my bros. Thats about half a mile away.

Im not proud of my exhaust choice, but it was ALOT less money than the RB full exhaust. I now want an RB full exhaust though since having to start carring earplugs in my glove box for passengers.

bigdv519 01-26-05 11:57 AM

I Love the look on peoples faces when I fly by their car and shift from 2nd to 3rd and they hear that earth shattering POP, and they know that I harness the power to fry the shit out of thier front bumber. 18" blue flames are no joke.

F1blueRx7 01-26-05 12:06 PM

Not the same thing, It requres pressure from the split air pipe, cut that pipe off, and you won't have any pressure to open the ports. Back pressure on a piston car has something to do with valves and lift or something. Who the hell knows I hate over complicated systems :)

I plan on picking up the RB 3 inch turbo back exhaust some day. It's so nice, and it sounds GREAT.

everything besides the muffler is racing beat... (the header and the presliencer) besides Imm ahave a resonator =( I dont want it to be loud...

couple more for show.... And for that guy who said is bad rice? This is not a cheap 30 dollar ebay muffler. this is the real (200 dolla) JDM tanabe YO! ge it right mad quick!

Well instead of wasting your money on a rice cannon you should have picked up a borla cat-back. Or RB mufflers...

totallimmortal 01-26-05 12:28 PM

it will be loud even with a presilencer, mufflers muffle the noise and that one won't. Personally i like loud and i don't mind that muffler i think dual looks much better andf racing bea sounds better but i'm sure it'll sound good and loud

RRTEC 01-26-05 12:41 PM

BTW, what do you think the difference between a $30 ebay muffler and your "JDM" muffler is? Nothing.. Really. If you look inside your "jDM" muffler it is just a straight piece of pipe with resonator holes and packing inside a pretty 304 stainless can....

SO IS THE RICER MUFFLER..... It's all about the packing when the pipe goes straight through there is no difference.

You essentially wasted your money by overpaying for a "brand Name" ricer muffler.

I'm sure you will be happy with it.

But don't fool yourself thinking that you are better then the $30 ebay guys when they just happen to have an extra $170 to spend on other things..

Well, not to be a dick, but a lot of the times the actual materials and welds are higher quality, sometimes they are not. But the welds on my apex'i n1 are quality. looks like rolled coins, you won't find that on ebay peices.

k1n0y 01-26-05 12:46 PM

Thats coolz you guys have Huge Tips... WOW wup wup for you... I got the JIC turbo back 90spec. Meaning 90mm piping from the turbo back to the canistor. Oh yah 4.5 tip.

So leave your lito cars parked on the side of the road at the runs. and ill burn all the cars from turbo charged hondas to saleen mustangs. Meaning far east coast from far west coast i got it covered.

Ps if you beat me on the straight. "lets take it to the mountains!"

1987RX7guy 01-26-05 12:48 PM

13bpower 01-26-05 01:20 PM

Geeezzz people, get it straight. The RB presilecer that he says he is getting will hook up to the stock split air pipe to provide the backpressure to operate the 5+6 ports.

Anyways, I say kudos for going for all out free flowing! Plug your ears, its gonna be fun... or loud.

I had an Apex-I N-1 on my (dare I say it) 95 Accord 2dr.. It was constructed well, and I agree the welds were pretty.

BUT- I ordered the two knockoffs for my 7 from speedycarparts.com and they looked identical and sounded just as good... Now check in 10 years and the difference may be noticeable, I don't know...

totallimmortal 01-26-05 01:38 PM

well i wouldn' t count on that sutup having enough backpressure to open s4 ports but niether does my setup so screw it. lol just get a electric airpump. And also although some cheapo mufflers aren't bad i wouldn't trust a cheapo muffler to last with rotary exhaust, so not a bad choice with the muffler but i woulda gone with a cheapo first and if i liked it and it didn't last then get a better one of the same design but better quality

Peruvianrx7 01-26-05 02:39 PM

well i think teh fact that i have a presilencer and an 18 inch resonator added to teh muffler which has a silencer would give me at least that 1.8psi needed to open the 5th and 6th ports.

HenryV 01-26-05 02:51 PM

Backpressure on any car (disregard the 5/6ports opening) is bad. From piston to rotary, anytime you have backpressure, you're losing hp/tq.

The reason you want an optimized pipe size is to have the maximum volume of exhaust gasses moving at the highest velocity speed. That's why you can't go too big, but also why you can't go too small on the pipe.

gingenhagen 01-26-05 05:44 PM

The huge muffler doesn't look too bad as long as it sits flush with the bumper. That gap makes it look really bad though.

Kinda. On a piston car with a big cam and lots of overlap (and maybe a high overlap rotary?) the backpressure helps keep the combustion chamber from being scavenged which is just a waste of fuel although it keeps EGTs lower.

coldfire 01-26-05 07:15 PM

well at least it is a quality muffler, and i like tanabe's products.
that said, it is a lot of money to spend on a muffler like that.

oh, and if you can't get the 6pi working correctly, check out the write up in my sig.

Peruvianrx7 01-26-05 08:33 PM

damn thank you bro you rule. Yeah hopefully the resonator the presilencer and teh silencer on the muffler will create enough back pressure if it doesnt Ill go ahead and try ur mod

Bigretardhead 01-26-05 08:52 PM

I just wanna see pics of it installed.

Wrong. Many piston engines will lose power and even be damaged from to little back pressure. the valves need backpressure to seat properly. And a two stroke can burn holes in a piston from running no backpressure. But, on a rotary your right they don't require backpressure and love to breath mainly do to more exhaust pulses than a piston engine. I run 2.5 inch pipe from the header back to racing beat catback, that exuast and a cone filter dropped 1.1 seconds off my 1/4 mile time, but i lost the 5/6 port which i hooked up a seat lumbar pump to be activated by a switch.

Crixtala 01-26-05 09:08 PM

I love how many people hate on exhausts that are angled and the such (like Apex'i N1, which I have in dual form), but think the RB exhaust is a God send... all these same people think that Honda's are from Hell... how does nobody think that they sound exactly the same. There's a guy around here that has an N/A S5 with the RB exhaust, and it sounds exactly like my friends Integra GSR with Apex'i N1...

Check out mine. Same size, maybe even 4.5 inches.

Man those are pretty far under the car. Ive seen another NA that had a single pipe about 3 or 4 inches under, as in not flush with the bumber. His bumber melted.

jacobcartmill 01-27-05 02:44 AM

attn: everyone.


get the RB full exhaust. god actually created this exhaust.

NorCal90 01-27-05 02:58 AM

jacobcartmill, are you talking about the true dual setup RB makes? If you are, that system is beautiful and I applaud your good taste.

RotaryWeaponSE7EN 01-27-05 09:02 AM

Yes the dual true dual setup would be good for a n/a, but a dual setup for a TII would be a waste of power.

Crixtala 01-27-05 09:14 AM

Here's mine, and I've yet to see any exhaust that I think looks better... or sounds better.

Drag'nGT 01-27-05 09:15 AM

Since it's a namebrand muffler I'm gonna go along and say that it's not that bad. If it was a 3A racing POS from PepBoys, then I'd say no.

Drag'nGT 01-27-05 09:19 AM

Nice.

Some type of rear bumper add on could help make those look more 'in place'. As flat and short as the rear end is on an FC I like seeing a rear valance of some sort on the back to help hide the canisters and let just the tips poke out.

hondahater 01-27-05 09:22 AM

I don't think big tips look bad at all on an rx7. I don't know what it is but on honduhs they look just dumb but on our cars (maybe because they aren't econo boxes) they look great! I would almost rather a bigger tip muffler than the stock, I think it is more proportional to the body.

drcoopster 01-27-05 10:19 AM

I like the stock system for sound and looks. A little louder wouldn't be too bad, but I like to be able to hold conversation in the car. If I want to hear it, I'll open the window.
