Thanks for all the info guys. bbf, I know, it’d be amazing if mufflers and resonators could achieve that sound with a totally different engine type. But like you said, unrealistic. I was looking for something a little “meaner” when I romp on it. To be honest I may end up leaving the exhaust alone and just adding some tips like the picture below.
Once again. Thanks for assistance on this. Seems like I’ve found the right place for my needs / questions.
