stock pipes

Has anyone tried to remove any baffles or anything from the stock exhaust for a deeper sound or more performance?

what exactly does the baffle look like? I have full documentation and did not see a breakdown with a pic of the muffler cylinder and baffle.
Thanks

You will lose back pressure that the baffle provides. It's fuel injected. You're o2 sensor won't know what to do. You'll end up tearing the engine up.

Fp3 has a option for no baffle I think. It'll tell the fuel management system to expect that though.

I like the sound of the Vance and Hine pipe. I just added the naked intake and fp3 computer. Now it sounds like a Nascar car when you really get on it.

Just got the Two brothers racing comp slip on and it sounds like a sexy BEAST!!
It looks sharp also if you like the long exhaust look.

Save the time, effort, and money lol. Get a Firebrand slip-on. Cheapest of the bunch and WOW what a difference in noise and performance.

Add the hi-flow intake and FP3 and all set.

Easy work too and all things you can do yourself.

Choices, choices, choices



Best,
