I tried going to a muffler store and putting on a restrictive muffler on my twinloop as I got my noise test tomorrow. Can't seem to find a stock exhaust anywhere or an audm cat or header.
Do you think a twinloop bpipe, jdm cat would put it below 90 with the new muffler?
Probably a stupid question as you don't know what the muffler looks like.
