Hi guys, I'm trying to quiet down a certain vortech charged itr as it's god awful loud with the 3" thermal exhaust and 3" cat.....

I'm thinking of just getting a mugen twinloop muffler for dc2 and mating that somehow...

What are the dimensions of the twinloop axleback, and going rates for such (it need not be new)?

I've already inquired of John Grudynski at hytech if he could do a 3" twinloop and the answer is negatory... not enough room...

Here is a decent thread describing the Mugen T/L. It appears that the piping is primarily 60 mm (typical of JDM exhausts) with smaller piping forming the "loop". Either way, it's geared more towards noise reduction than performance, especially when dealing with a forced-induction setup.

 

Isn't the mugen only about 2 1/4" tubing? The HyTech is 2.5" I see that as being the better choice when going from 3". It'd probably be a bit cheaper too.

 

Go with the 2.5 hytech. It is a great muffler, but does get quite loud (compared to stock) at certain rpms.

The mugen TL is silent as they get but your flow will suffer.

But it is still quite quiet

 

at this point, my concern is getting the car quiet vs making power - it makes more than enough.

 

I believe the actual can piping is 2.5" the bottlenecks int he mugen system are mainly before the Big *** resonator.

 

the piping before the resonator is 54mm, everything after it is 60mm

 

i have a question about the mugen. anyone been pulled over by cops with it? looks wise is the canister that visible from a cops perspective? these modified exhaust laws in cities are wrecking my twin loop plans.

Anything can be pulled over. I've had friends been pulled for stock exhaust so thus even the mugen.

werd, her car is LOUD!

 

yeup. 2.5 " t1r b pipe and mugen TL axle back works good for me.

it's only loud when i rip it

 

Dont get the mugen, it will rob power with your setup.

 

The twinloop is a great NA muffler.
Dyno proven, when running the entire catback, removing the twinloop looses power and torque.

Flow restriction my ***.

FI is a different story of course. Iv never seen a boosted honda with a twinloop.

fastvteccl on here makes 280whp with his twinloop and jrsc...

I don't care about the power loss - I care about the noise reduction!

We already have a 3" straight solution, just need something more geared towards being quiet and not attracting any unwanted attention...

Who sells the mugen twinloop - just the axleback? Hell, I guess I'd take the hytech twinloop and put the mugen tip on there for ***** an giggles....! lol

VTEXTC, can you provide us a graph of this? it will give me motivation to reinstall my mugen tl

Are you looking for the catback or the axleback?

If it's the catback, wouldn't that be the standard way the 無限 exhaust is sold?

 

IMO, I think the hytech would be a better solution. Its practically the same as the Mugen except no Bottlenecks and cheaper. It is very quiet, louder when you get on it, but still quiet

I meant axleback - just the can portion... mis-typed, but have since corrected it.

 

I too have a JDM/T1R/Mugen setup ... JDM 4-1 header, T1R resonated test pipe, T1R b-pipe, and Mugen TL muffler. I'm making 206whp and it is quiet as can get. It so quiet I've had friends ask me if I went back to an OEM exhaust !!! Of course, when you go VTEC, you'll hear the exhaust; everyday city driving sounds barely louder than OEM. I realize I'm running a NA setup versus your SC but I would think the boost would actually make the exhaust quieter.

BTW: the inlet on the Mugen TL is just around 2.5".

If that were the case, why would Mugen list the Twinloop as a 60mm exhaust?

I think you're thinking of turbocharging. Turbos as they're inline with and a part of the exahust tend to muffle things a little bit. The SC would not.

That's exactly right.....!

My cammed and itb's hatch with side exit exhaust isn't nearly as loud as this vortech sc'd itr!

 

Does the 2.5" twinloop setup from hytech not fit the bill?

I think he's worried about it being too loud. Its still one of the quietest exhausts out there though. Not much louder than the Mugen at all.
