Hello,
I emailed Thermal R&D yesterday and they have told me they don't make a silencer for any of their exhaust systems.. Does anyone know how hard, and if it's possible, to fabricate a silencer for it? Has anyone else done this? Probably not, but I figured I'd see if anyone has any ideas..
Also, I've been considering getting the Arospeed "Exhaust Valve Controller" ( http://www.arospeed.com/newstuff.htm ) thing which can be used to change the amount of exhaust getting through the pipes at once by a valve that closes/opens up when a switch is pulled.. If I were to go that route, I'd definately buy a test pipe to hopefully negate the HP loss from using it.. Anyone have any thoughts on this? I know Apexi makes one for the Japanese market, but not in the US.. Arospeed's the only company I know of, and it's on their new product list so I doubt very many people actually have one of these things.. But any input on the whole thing would be cool..

PS: Sorry for rambling

I suppose that'd work.. but seems like kinda a waste.. putting basically a throttle body in your exhaust.. hehe. You might want to think about putting a resonator in farther up stream.. that'll quite it down some.. and possibly give it a better sounding tone.

AUGHH!! i totally needed one of those but i got rid of my SP already!!! F*CK!!!!!!!!!!!!!!!!!!!

Thermals are already pretty quiet, one of the quietest exhaust systems i've ever heard. You want to quiet even more??? Well dats coo' Like Breezio said, try putting a resonator further upstream.

P.S. welcome aboard..........pun intended :-D

i believe that you can use the same silencer that is used on the apexi n1 mufflers..

Wouldn't a resonator add restriction? I guess anything would, but with a silencer I could choose to be restricted or (about 99% of the timer), be non restricted at all.. How hard would it be to fabricate a silencer do you think? Hmm.. maybe I'll market one if I ever make one =)

straight through resonators (cherry bombs, purple hornies, and other glass pack resonators) add little to no restriction. I think all resonators are straight through.
