Does anyone know where i can find a mugen twin loop axleback for my 00 SH online? whats a good price i should pay? thanks

 

Well... you have multiple options.
1.) call up Kingmotorsports.com and sound goofy by asking, if you can buy just the muffler. But they'll laugh and call you after you hang up.
2.) call up kingmotorsports.com and order the complete system for 1000+ and when you get it throw away the cat-back piping part.
3.) try to find someone online whose willing sell you their muffler, not likely though.
4.) Most likely you'll never find it because of the fact the Mugen is so prestigious that people don't do things that you're wanting to do, and they just go ahead and get the complete system.

If you want a cheap alternative I think DC sports sell and wanna-be twin loop system.
I'll throw this in just to be a jerk and make you envious.

Sorry for the flame but very silly request

 

or you can get a copy they're selling on ebay.
