Musarri slip on

I really don’t believe you would need to tune or get some ECU modulator for a slip on. The cat is in front of them slip on, and I don’t believe there’s any hp to really be gained from the slip on. Popping is just a loss of back pressure, and it won’t hurt anything, the original huge muffler probably had poppong too, it was just too silent to notice. You do you, but if a dealer tells you to tune a slip on, I think that dealer wants money for doing nothing and that’s bad business.
