As JC says, dont bitch its not his fault a bunch of ppls BOMB him with PM's about when its finish.. He got enough problems with his life.. And he dont need more things to stress about.
I haven't tested the SX out, but i bet its as awesome as the Supra, maybe even more, even though its not done! And the thing about non universal muffler is an easy fix when you know what to do!
Take care Robin! Nice you don't quit SLRR! 😃
