Instead of switching to one of these many glasspacks, why don't you just switch to one of Flowmaster's quiet mufflers? After looking at their website, it appears that most of their mufflers are actually pretty quiet. It's only those 40 series mufflers that are loud. Check out Flowmaster, Inc The Muffler and Exhaust Technology Company manufacturer of performance exhaust systems, mufflers, exhaust kits and look up their 70 series muffler. From what I can tell, it should be almost stock-quiet on your truck, and apparently you won't sacrifice any performance at all.
I'm thinking of trying one of those 50s for my '97, since it also has a 40, and is pretty loud.
40s are one of their more quiet mufflers. 44s and 10s are ridiculous loud compared to 40s.Originally Posted by 97Stepside

???? Have you ever been to their website? I've been using Flows for 20 years, and after having mainly 40s on about 10 different vehicles (from BMWs to my last '02 Chevy truck) , I'll vouch for them being very loud. If you check the site, the 70 is the quiet one (supposedly really quiet on cat-equipped vehicles), and any 40 is the loud one (40, Super 44, Super 40, deltaflow 40 [why they need that many!?!?]). Their 50s seem to be somewhere in the middle. It's really kind of confusing- I don't know why they need that many different mufflers, but I'd have to say that most of them are a lot quieter than people seem to think.
lol. Want me to show you videos of three identical 5.3s, one with 10s, one with 44s, and one with 40s? I own two of the vehicles, so that isn't really a problem. I promise you, the 10s and 44s DOMINATE the 40s. I said the 40 was one of their quieter ones, not the quietest. Yes, a 70 is more quiet. 40s and 50s are comparable.
