I know its not required to do with slip-ons. But i been thinking the the next time i change my oil is to do the pair valve mod. And kinda figure on doing it now so when i have the extra cash for a full exhaust system the pair mod already been done.
Is there any avantages or disavantages doing the pair valve mod with slip-ons?
