1985 Other GMC Models Exhaust Question

yes its safe, but loud and illegal also if you have immisions testing its illegal. also removing a catalytic convertor emissions or not is a federal crime.

if you want it louder you can put on a glasspack instead of your stock muffler. the tips are for looks not sound.

you can go with a true dual exhaust with high flow convertors and glasspacks for the loudest combonation, it will be loud accelerating or crusing and emissions legal, dunno if the cops would like the sound but if your lite on the pedal shouldnt matter.

id go with flowmasters have a very unique and good sound. loud on acceleration quites down when crusing.
