I'm going to install my exhaust after the Niner game and I'm wondering if there is a break-in for the HKS exhaust? Should I break it in or do I don't waste any time to rev to 9? Thanks. Latez!

 

I realy kin't dink uh a reason o' requirement t'bust-in an 'eshaust. Man! It gots no movin' parts.

I don't believe exhausts have a break-in period per se like engines do. However, I have heard that exhausts will 'settle' down after about 500 miles of driving. I think it means that it quiets down after a bit of driving after the packing material in the muffler 'breaks-in'
