Default okay, so best way to get a Mugen twin-loop from an Si onto an ITR?

1st of all: mods, sorry for the semi-duplicate-post, the other one wasn't titled very well and so I didn't get really the info I needed...

So I got a Mugen twin-loop off my roommate's Si (bagelw) because he's a traitor and selling his soul to go the way of AWD . Anyway, I posted asking if anyone knew if the Twin-loop itself (just the muffler) was a single model, or if there might be seperate versions for the Civic and Integra platforms. I should have just asked, "how to make it fit?" Well a couple people said the canister is smaller on the Si then on the Integra (which will affect what?). Then it sounded like someone thought it would just bolt up. Well it doesn't, like I said I didn't think it would.

The bpipe is longer on the Si, so there's no way it would fit:
I went ahead and pulled it off to see for myself since I didn't get any definitive answers:

(the reason the bpipe on the Mugen looks weird it was originally 2.5" pipe from a JRSC owner, and then the 2nd owner had their stock Si 2.0" pipe welded to it)

And just for grins,

this is with the pipe fitted up, not bolted though, but either way, nope, it ain't even coming close to fitting, it's too long.

can I simply have the existing Mugen bpipe wacked off and have a shorter one welded on that would fit up to the ITR? Or will I have other issues, like the hangers being different, or the way the twin-loop piping fits up around the bumper itself? Since I can't get it up in there to even see how close it would be, I can't tell if it would even tuck in the bumper like it did on the Si.

edit:
okay well, I did manage to get it crammed up in there to see if the hangers would come close to lining up, and it just doesn't look like there is anyway, even if I moved the rubber hangers to the other hooks, no way.


so yeah, i'm pretty much answering my own questions here and wasting honda-tech bandwidth by thinking outloud.

what should i do? i think it would fit if the hanger rods on the m00gen were extended, and the bpipe was correct length size, but that's gonna be a bit of work. hmmm

edit again: damn, running the R with the muffler completely off is just glorious. Makes me feel like I'm in the hatchy at the race track except that my ears aren't numb and ringing even with ear plugs in It sounds really good... I mean I wouldn't want to listen to it all day or anything. It seems to breathe so well, and when VTEC hits, damn, I'm pretty sure I wet myself. As a matter of fact, I'm going to drive it to work tomorrow like-as while I figure out what to do, just to upset all the suits at the office, lol

I believe so.

Maybe you should just sell it and get something built for the car and you'll have less headaches in the long run.

Amen..see my post here https://honda-tech.com/zerothread?id=637733 detailing the Kteller8's piping, then you can still use the twinloop muffler, I assume that is the idea.

Sell it for what its worth with rust and big ding in it. Don't put something 2nd rated on your R.

If you really want just take it to a muffler shop and the'll chop it up and make it fit...

IMO: not worth the money or time to do so.. If you decide later in the future that you want to sell it, it will be very tough compared to selling it now and getting something that is made for your ride. Just my 2 cents.

Yeah, for some reason, Si mufflers sit way farther back than on DC's. When I first bolted up my DC Sport muffler off an Si onto my GSR, and the tip stuck out like 8 inches past my bumper! Fortunately for me, the DC Sport's tip had a long neck that I got cutt off, but your Mugen twin-loop's tip meets right at the muffler, there's nothing to shorten. Your only other option is to hack off some of the "over-axle" piping, and relocate your hangers a couple inches.

You guys crack me up... oh no, it's got a ding and some, gasp... rust (and it's not even rusting really, it's no more "rusting" then just dirty as any of the piping on the R all ready). Have you guys looked under your car lately?

Seriously... why would I spend somewhere in the neighborhood of a grand for a few hp? I don't understand why people spend so much on an exhaust, when there is power to be made in so many other places. Yet people buy bling-bling Ti exhaust piping and expensive JDM fart cans that are probably no different then any APC t00b muffler you can get off Ebay.

I just want a little more flow, without the cost of my hearing or my pocketbook. If it even made 1hp increase, it'd be worth it because it's FREE. I've always said if I was going to replace the already terriffic ITR muffler with anything, it would be a twin-loop design or something high-flow and not straight though, because I've had personal experience with both and I like how quiet and non-ricey the Mugen sounds. So this one falls in my lap for free, but it's not a "direct bolt on" and everyones solution is to sell it and get something that bolts up? oh come on...

If building a race car has taught me anything, it's that spending gobs of money on name-brand, bolt-up, bling-bling exhaust parts, is a waste of money (and in other modification areas too). My Civic (see sig) has a 6' long, 2.5" straight pipe to a 12" straight muffler and a turn down, and it cost me like $50. I mean, it's just a damn pipe, and when it comes down to it, that's all any of this is unless you care about the bling. (and yes I know that sizing and length and bottlenecks matter, but it's still just some damn pipe)

You've got a point

Go with a Spoon N1 and Be happy Looks like the Twin Loop is too much of a headache to get to work on there. The Twinloop is a nice Piece though

Jeez, I since some hositlity..You asked a ?, we answered ...Did you happen to see my post in the link supplied above..No JDM bling whatsoever, (except maybe the T1R muffler but your choice on muffler is up to you, you could even use the twinloop), loud...most likley.

It sounds to me like you should just leave your stock exhaust on, and sell the twinloop...You don't care about making power, you don't want to pay for it, and you don't want it to be loud?...sounds stock to me.

So pocket some cash from the twinloop, and leave your R alone.

Heh, I was mostly talking about the "oh, it's an aarrRRRR, bow down before it and only put shiney chrome JDM bling on it and leave the rusty dented hideous exhaust off because it's not worthy!" type of attitude. Yeah, I did read your post, and I would do the same thing, (though I wouldn't bother with blingin pipe under a car where no one is going to see it) except that with no resonators and that straight-through exhaust, it's gonna be hella-loud. Sure, if you're comparing that to your friends open-header setups, I'm sure it'll be quiet in comparison. But that's not what I'm going for. At least not on the street, I mean, why? If it was a race application where I didn't care about how loud it was because I was wearing a helmet and earplugs and wanted to get every last drop of horsepower out of my exhaust then yeah, I'd do that. (as it is with my loud-as-frick straight pipe on the race car)

I *do* want to make power, which is why I am going to make it fit and use it.
No, I don't want to pay, but I don't have to, because the Mugen was free.
No, I don't want my exhaust loud, hence wanting to use the free Mugen.

Free Mugen twin loop = Free power and meets my requirement of being quiet. So why again would I just sell it because of all the "hassle?"

point taken...

The reason I went w/SS piping is because I live in a area w/frequent snow, and that will prevent rusting vs. aluminized steel.

The *bling* piping cost me ~200...not bad IMO

Anyhoo, looks like you answered your own ?. Just make the twinloop fit, right?

I have the similiar case too. I just bought a Twinloop muffler and found out the flange is way too big than the stock ITR muffler. Does anyone know where could I get the flange that could fit with the Twinloop and weld it to the stock pipe? I prefer not to cut and weld on the mufller instead.

that's the plan

typerfans: an exhaust shop should be able to do that for you. I'm curious what care it came off of, since you say the flange is bigger. Have you measured the "loop" part of the pipe by any chance? I'm curious if the diameter of pipe used on the loop is different on various mugen's

Sorry Ben I have no technicall info, but i want to say that you got the hook up maybe i need to move to your area.

hopefully you will figure it out! That would look good and sound great! Good luck

here are the pics when I took off the stock muffler and compare with the Mugen twinloop.
The Mugen twinloop I got is for DC2 (pretty sure about it, since i have tried the test fit, the position fits perfectly, expect the flange is too big for the stock pipe)





and here is some measurement of the Mugen twinloop muffler:

the tip length: 210mm
the muffler length (without tip and rear pipe, body only): 300mm
the rear pipe length: 500mm

circumference of the tip: 280mm
circumference of the loop: 195mm
circumference of the rear pipe: 195mm

the total width of the flange: 155mm
the inner width of the pipe: 62mm

Hope this information helps.

okay, your pics confirm that the DC2 canister (and overall it looks like) is bigger than the Civic can on the Mugen, you can easily tell that it is bigger in the pic. I'll check the actual measurements tomorrow.

I also measured the pipe diameter of the Mugen/stock earlier, and the Mugen was exactly 2" and my ITR pipe is about 2.1". (couldn't find my tape that had metric measurements) Still, they're pretty close, (my Mugen pipe vs. stock) and I doubt it would be a big bottleneck or anything, but obviously Mugen designed the twin-loop for the DC2 larger then they did for the Civic. This is a disappointment to me unfortunately. You said 195mm diameter, but i think you meant circumference. Because 195 would be about 7.6 inches. Though, you said the inner width was 62mm which is almost 2.5". So I'm guessing you have a 2.5" exhaust setup on yours, which I would not think is for a stock DC2/ITR setup. Anyone else care to shed any light on the diameter of pipe used on a Twin-loop setup for an ITR?

So does it look like the flange on your Mugen is original, or maybe added later? Maybe someone had it bolted up to a different cat-back with larger piping/flange.

so I'm not sure what I'll do now, only because of the significant size difference (smaller) makes me worry that it may not be much of an improvement over the stock ITR muffler. I could use this as an excuse to do some dyno runs before and after.... got a hookup on dyno time now, but we'll see. Typerfans, let me know what you find!

oh, and the jack is from Harbor Freight, weighs about 35 pounds, costs $159, and sits only 3-1/2"'s to the ground which is great for my lowered race car

edit: spelling

I would assume he meant circumference, because the only way he could measure diameter accuratley would be w/a set of dial/digital calipers, and most likely he used a measuring tape..that would also explain why he could attain the inside diameter 62mm, because that would be visible to the the eye..

Or, we could just wait for his response..lol

Also some of the hangers on the Twinloop look similar to what I received w/my setup. (of course exhaust hangers tend to be very generic )

Couldn't you just have someone weld the hangers, any for that matter in correct position on top of the loop, but relocated farther toward the back, for the DC2 chassis.

For example, if this is the DC muffler, the hangers actually look like they are inverted, and moved farther back. vs. the Si Muffler you have pictured above.

DC2


Si (now, couldn't you just move the hangers back, and invert them as shown above on the DC2 muffler?



clear as mud, right?

you could do that. but i have the twinloop on my car and the dam thing keeps fallig off in the correct position. i sugges you put hose clamps, yes hose clamps on the end of the hanger after it passes through the rubber before you invert the hangers to the other side, i think it will work!
