So, how exactly do those twin loop muffler's work?

anybody have a picture of the inside's of one?

 

It's like having 2 strait through mufflers side by side, then having the output of one loop back and go into the input of the 2nd.

It makes them really quiet, but does not block the flow like a normal mufflers would.

interesting... never knew this...just getting into cars

 

What the guy said before me. One other note. I really don't know the benefits of a twin loop design for auto-x/roadracing. Might be good for auto-x bacause its kind of restrictive and allows a bit more torque. But might not be great for road racing.

 

my friend put that thing on his prelude. it looked like a tuba. weighed a ton, too. it was only 2inch ID, which is too small for a 2.2 liter, but great for a 1.6.

restrictions in the exhaust don't increase torque. that muffler isn't going to give you any added backpressure anyway (not a measurable amount), since its mandrel bent piping, assuming that its a straight through design. the increased length of the piping will give you more low end though.

 

i love twin loop mufflers; they sound nice

 

every 90 degree turn is the equivalent of 5 feet of exhaust tube from the flow's perspective.

I changed my exhaust, I went to a JDM ITR header, 2.5" test pipe, 2.25" back to a 2" straight thru design canister. I lost low end power, probably gained some high end. I think I lost too much backpressure, I'm looking for that happy medium where I have both low end and high end power. Any suggestions?

 

hell yeah love my mugen twin loop sounds wicked in vtec though

maybe since I am running test pipe

but still it is nice never the same tone gets deeper or quieter with the conditions of the weather and level

I trip out sometimes on that

Okay going from 2.5" to 2.0" is incredibly stupid...that's why you lost power. Maintain a constant diameter or increase as you travel towards the back of the car if you must.

 

Twin-loop mufflers pretty much offer the sound deadening of a chambered (like stock) muffler but flow like the 'N1' or cannister mufflers. Sort of the best of both worlds...just at a price.
