Default Muffler performance

Question, will I get the same “performance” from debaffling my mufflers as to buying a set of Rinehart slipons? It’s more a back pressure question. I’m going to tune it with my FP3. If I don’t need to buy a set I won’t. I live my debaffled oem and live the look, just don’t want to hurt airflow or performance.

on your stock mufflers all you can do is open the back end up with a hole saw, then there is nothing in there its a hollow muffle can. the sound is loud and you will get a lot of backfiring. I know a few that did this. but a good set of mufflers the way the exhaust flows through the baffle design creates back pressure and each company's muffles have a different sounds. the main thing is to get rid of the catalyst in the front head pipe it will perform better with it gone.
