Im looking into getting a twin loop muffler setup. I know these things are quiet and sound nice but, with 2.5 inch piping, jdm itr header, and a test pipe, how would it sound without a resonator? Im more worried about it being raspy more than the noise considering i have an rsr gt2 now. Please post up some input

 

i've got a hytech replica, test pipe, 2.5" bpipe with resonator and mugen twinloop and its really nice sounding. a tad raspy but nice and deep. i have a dc 4-1 2.5" collector header for sale.

 

test pipe = raspy
no resinator = raspy

put the two together, no muffler is going to save you.
Throw in a standard length resinator and a cat or glasspack and it will sound a lot better.

 

what about a resonated test pipe!?!?! just kidding. whats a good sized resnonator to run on this thing? And a stupid question about them, what does the resonator actually do? slow down exhaust, create back pressure? Does it cause more cabin noise?

 

bump, i need some mo input

minimal cabin noise if any.

glass pack is a resinator with sound absorbtion material fastened to the insides.

The resonator reduces or cancels out some noise (frequencies) from the original exhaust sound. The amount of noise or what frequencies are removed depend on the diameter and the length of the resonator. Remove it all together and that is why an exhaust will sound raspy. That is the frequency range that is removed by the resonator. The longer/bigger your resonator = the deeper less raspy tone.


*Edit* Relic1 beat me too it good info in that link
