I believe there are aftermarket valved exhaust’s that give you a remote to be able to change the loudness.
Lastly you aren’t going to gain any additional horsepower from changing your mufflers. Those days are long gone where you could change the muffler and gain horsepower. Manufactures these days do a much better job when designing the factory mufflers for pretty much every single car you can buy.
The only way you can add horsepower through a vehicles exhaust system is if you remove the catalytic converter (which I don’t recommend for the 10 hp gain) or going with a long tube header system + a tune for it.

Thank you for the truth, and not sugar coating all the facts. Yes, CATS would be about the only way with a Magna flow exhaust muffler set. Manufacturers are doing much better adding those additional hardware features with current models. I like how my setup sounds. I guess I'll be adding an after market cold intake and throttle body for now. Thanks!
