Hey just bought this exhaust off some guy on CL for $100 who says its a HKS Dual exhaust. The previous hit a curb and messed up one of the mufflers so I'm trying to buy a replacement. However, I've looked around and cant seem to find anything that looks similar to this or that has the same type of measurements.

Shell diameter ~165mm
Shell length ~343mm
Tip diameter ~115mm
Tip lenght ~ 165mm

Thanks again!

 

looks like an Apexi N1 dual to me
