It will get a little louder to everyone outside it, BUT it will get MUCH louder to you when you cut it. Mine is cut and dumped after the muffler and it is louder, but you hear it a lot more in the cab. At speed it creates a semi-annoying drone. Its livable because I still have the muffler. But since you have no muffler, that drone will vibrate your teeth loose. I really dont think you should do it. It will sound cool at first but you will get annoyed soon after.
But if you do decide to do it. Make sure you use turndowns and put it/them far enough forward of the rear axle so that you arent blowing hot exhaust on the rearend. Do not try to go without turndowns.
