Exhaust Dumped and cutouts
 

Ok guys, my knowledge on exhaust is very limited. Could some one explain to me when something is 'Dumped' and what cut outs are? Thanks!

Dumps are turn downs, they don't come out the rear or side of the vehicle. They come down right off the muffler or other such device.

Cut Ous are exactly that, they are a section of the pipe that has a removable section that allows the exhaust to come right out, bypassing the muffler system all together.. This also makes the car loud, and isn't recommend because you loose a lot of backpressure, and the car usually sounds/runs like crap while they are out.
