Glasspacks on an LT1
I second this, they sound awesome and aren't 'too' loud at idle, but at WOT they sound awesome. This is an extremely opinion based question find some sound clips and w/e you do don't jump on any bandwagon. this is completely personal preference. I have the lt4 hotcam>LT's > true dual/x pipe > summit bullets, sounds awesome I wouldn't have it any other way.

I have Hooker Aerochambers with true duals all the way out the back. Best sounding muffler out there I think and it's not real loud either. It has that ping to it, love 'em. If you just want loud then go with dumped duals.
glasspacks are garbage, thats why they are cheap, and available in stock at pep boys. cheaply made, simple design, sounds like crap, garbage. blowmasters sound ok on a stock lt1. because they have chambers and restrict the air to create a sound to make the car sound nasty. when the car is nasty, you want an exhaust that will let more of the natural nastiness out.

Mine are fine.. like i said pacesetter LT's to 2.5" x pipe dumped at axle.. it doesn't drone, and isn't that loud until about 3k rpm. I think alot of people on here haven't even heard a system like this in person (not you). its really not that bad? I don't see what all the fuss is about. It sounds awesome too, i can't stand flowmasters/borla/magnaflow.. just garbage sounding IMO...

Please don't do it. I have 3" true duals with glasspacks. It sounds OK at WOT but I hate how it sounds cruising. It doesn't sound like a truck but it definately doesn't sound great. I only got them cause I was poor at the time and spent like $15 each at summit for em hoping that they would mellow it out a bit. I'm planning on Moroso Spiral Flows sometime soon to replace them. I have a few WOT vids if you really wanna hear what it sounds like.
My setup is lt headers, 3in ypipe, dynomax bullet (essentially a glassback), followed by the beautiful/unique sound of a moroso bullet. Boom you have a great sounding lt1, no rasp, sporty, not to loud and it didn't even cost me $500.

No glasspack.. it's too open no back pressure. ^^^^ like he said moroso spiral bullet!
