I wanna make my '84 spree sound more "tough" so I'm thinking of cutting off the back end of the muffler, and hollowing it out. Would loosing that much back-pressure really matter? What other ways are there to making it sound tougher?(without spending money)

yes, loosing that much back pressure would kill the power of the motor.

instead just take a long drill bit and drill in the back of the tail pipe, drill out 2 baffles and you will keep enough back pressure but still gain performance and you will should cool.

They sound real mean with 2 drilled out.

How long and how wide should the drill bit be? How far appart should they be drilled?
