I'm thinking of either putting Thrush welded muffler(s) on or dual 3" glasspacks with 2 1/2" pipe. What would the sound difference be and has anybody ran a similar set up?

Mufflers have tone, glass packs are raspy and pop, not my favorite for sure.

I have ran several Thrush Welded Mufflers. They are great for the price. Nice mellow tone.

Dual 3" way too big, unless you cruise over 5000 rpm for long periods. Dual 2 1/4, or 2" even better for low end grunt.

I want something that's mildly loud and has an aggressive tone

John, shoot the vid, then load it to Photobucket, get the link, and you can post.

They have two sizes 4x9 and 5x8. Would the body size make that much of a difference?
