I'm getting a new exhaust done next week and I just wanted some opinions from people who have already done theirs with these two glasspacks. I was thinking of 2.5 inch piping splitting into a "y" pipe going to two glasspacks for a dual exhaust. What I was basically wondering is which one (thrush glasspack or the dynomax bullet) would sound better and also work better for my car (i.e. enough backpressure since I have a 94 base 3000GT)?? I won't be removing the cat or pre cats. Thanks for the help!!
