Glasspacks on a burb....Wow. I've just never heard of anyone putting them on a burb. Street rod, sport truck, but not a burb....yea some plans i have for it is changing the mufflers to something deeper than the glasspacks that are on it right now. rebuild the motor and just getting it nice on the inside and out.
I'm with Darcy, Flowmasters...check it outDoes it have true duel exhaust? On my 87 Blazer, I put duel exhaust with glasspacks on it in the mid 90's. Years later after they get burned out the get loud and sound terrible so I switched to Flowmasters (not sure which series either) but it sounds awesome! I'm sure it would sound even better if I had headers. Welcome to the site and good luck with your Burb!
Nice sound bytes.
