was looking on ebay and found this...I dont c there being any gains, but i figured i would post on here and see if anyone has any experience with these type of mufflers...just caught my attention...

 

Honda junk IMO. Look at those 180 degree bends, jeebus.

 

Thats what i was thinking! But figured i would ask anyways hehe

 

Offtopic: But is that picture of the engine in your sig suppose to be a DEK?

 

it says "parting out a DEK" right above it.

 

Thats trying to replicate Mugen mufflers for Honda's.

 

Please don't post info about products without checking your facts!

Mugen Twin Loop muffler

Silencing characteristics and the quest for exhaust efficiency: the two requirements imposed on exhaust systems have a contrary relationship, and in practice it is extremely difficult to achieve both. At Mugen, we have continued to employ the straight configuration, with the design philosophy that low exhaust pressure must be provided, and that reducing exhaust resistance is an important part of the ideal exhaust system. The straight configuration is widely used in racing, and is ideal because, as the name suggests, it provides low exhaust resistance. However, large silencers are generally required, as there may be problems with mid to low frequency band silencing and scattering of sound absorbing material such as glass wool with the straight configuration. Incidentally, the inverted multi-layer expansion-type silencer widely used by automobile manufacturers provides stable silencing performance, as the sound passes trough several divided silencer chambers, but involves the disadvantage of some output loss and is larger and heavier than other silencers. As a result of our quest for the ideal design for racing engines, Mugen developed the "twin loop-type silencer," in which the pipe is twisted into two loops and passes straight through the silencer twice. This could be considered the ultimate arrangement, combining the concepts of "absorption" and "intervention" in an ingenious manner. It surpasses normal systems in power and torque over the full range, and provides the required silencing and the clear Mugen-Honda sound.

100% bolt using the Mugen "Twin Loop" technology to produce a pleasant exhaust note without usual noise and a big gain in mid range torque and top end horsepower. Beautifully constructed from polished T-304 stainless steel including all flanges and hangers.

Retails for $768.00 from Mugen.

These were built primarily for Hondas.

 

So this thing adds two rediculous 180 degree bends just so it passes through the muffler/silencer twice to reduce sound and supposedly improve exhaust flow? Mugen might be the expensive-all-hail-to-the-king tuner for Hondas (which I have owned in the past), but that doesn't make all of their products great. Maybe I'm missing something, but how could this be any better in terms of less flow restriction than adding two "silencers" along a straight section of piping?

 

Why are you doubting it? Ebay says it'll give you 10 HP! No matter what car!!

 

This is very interesting info hehe!

has anyone tried one of these on the max? More curious in the aspect of Sound more than any power gains...

 

Yeah but it sure doesn't look like a DEK manifold atop of it does it.

 

Its extremely dirty genius, notice the VIAS box on the side?

 

This sure doesnt look like a post relating the loop muffler im posting about does it?

Please resort any questionss relating the DEK im parting out to my PM box...

thanks

 

Call the Mugen R & D and ask them. Don't ask me I just work here!

 

WOW, a bit feisty aren't we. I didn't mean anything by it and I could see how my previous post could be misconstrude.

Your right Luke it is very dirty and it is indeed a DEK.

Alrighty, back to topic. I am curious to see what it would even sound like, although I don't really care for the design to much.
