Question about changing exhaust and rejetting

[hotrodtba]

I currently have a Big Gun "Race" Series Slip-On silencer with the stock pipe. If I switch to some other slip-on, will I have to change the jetting? It has already been rejetted for the Big Gun. Any help will be appreciated. Thanks.

You'll probably be fine with the same jetting, but it's always a good idea to do a plug check.
