well... i'm not a muffler expert. as most though, have been around piles of cars. i've had piles of cars. i've had 2 sets of 3" duals. 1 was true dual with "welded" mufflers, all crush bent including 2.5" tails. if i had to describe the sound, i'd call it an 8 cylinder HD "barhopper". i like those rides as well, but they aren't for me... the drone was unbearable at cruising speed. i now have a homemade 3" x-piped dual exhaust running into 3" dynomax vt's(17957) with behind the wheel exits.(same engine) like most say, the straight dual 3" with "welded"s" would compare to an L88, whereas the 3" x-piped duals with dynmax vt and behind rear wheel exits are more like Z06. apples to oranges. they're both sweet depending on your palate. highway running is so much more comfortable with the vt's, standing beside the car with the hood open, i can hear the injectors pulsing, standing in front of the car with the welded's i couldn't hear the fan. i am waiting on new parts to come in right now. as soon as i can move the car to a good spot for recording, i ill record the symphony of sounds in several settings and share them here. i looked high and low for camparison videos, and they are few and far between. if you like Z06 style compared to L88, dynomax vt's compliment an x-pipe well..
