Thanks for the poll. I bought a piece of 4" from a muffler shop the same length as my banks muffler, and had the ends expanded. All i had to do was take the muffler out, notch the ends on the new pipe and install it. And it does sound mean.

I wish they made like a valve so you could run your exhaust through a straight pipe or a muffler. A valve that would point the exhaust through either one as you wanted. Cause during hunting season sneeking around with straight piped exhaust kinda don't work lol
