aftermarket muffler for the RX3
 

I can`t seem to get the search option working, so, I'll ask a question I'm sure was addressed earlier,

Way back in 2015 sometime, someone found a new muffler/headpipe, that fit the RX3,

If my memory serves me correctly, I think the pipe had the "torque tube or box" in line.
Any ideas anyone?

As always, thanks for all your helping.
