Im might be going thursday to have this done.

Whats the differences if any I can except? (expect the sound)

Is there any reason why I shouldnt?

 

No reasons, as long as you like the tone. The CATs are the issue. If you start removing those then you have other worries.

 

Oh no not going to do that at all just the muff.

 

Removing the muffler entirely, you`ll likely lose "some" back pressure, which will make the low-end torque a little lazier. Doubt you`ll see any increase`s in mpg or power either, it`ll just be slightly louder without the muffler... if you`re just lookin for louder, rip it off. You`ll likely have alot of cab drone without the muffler. Are you doing anything with the resonators at the tail tips..???

 

agreed...!!!!

 

was gonna have a custom y pipe put in

 

I`m curious, what sort of benefit do you think you will get, by doing that (???)

 

prob none more after sound then anything.

 

A "Y" pipe is unlikley going to change the sound, at least not enough to hear much of a difference anyway. If you plan on more engine mods later, then install a better "Y" pipe. I believe MAGNAFLOW makes a custom Y pipe. Other than that, its really a waste of time and money. Just my thoughts on it.

 

it changes the sound alot on it however havent did it yet been thinking on a actual muffler.
