Anyone know where to get silencers for universal mufflers? More specifically, for the Hayame ST-1 muffler (it kinda looks like a racing medallion). My friend has it on his car and is worried that his car is a little bit on the loud side. I'm not really sure if Hayame themselves makes silencers, but do you think a piece from another exhaust would fit his? Any help is greatly appreciated. Thanks! :thumbup:
