I want to add some sound to my 2000 blazer 4.3l my cats have been knocked out and I want to add a glasspak would like to stay cheap but what would you recommend I would like to be kinda quiet at first but if I get on you notice me

 

Check out YouTube for some examples. It's what I did to go with a flowmaster 40 series muffler.

 

go with , a Magnaflow and the high flow cat, if you want a nice purring rumble, the Flowmasters have a tinny sound , I have had both types , I like the Magnaflows, then Dynomax, then Flowmasters

 

I have a dynomax and a high flow cat. Like the sound

 

I've got a dynomax 2.5" cat-back. At low RPMs under high torque it sounds the best, but considering these V6s always sound a little funky I'm happy. As well, it's quiet inside, and loud outside, but keep in mind I have a 3.5" intake with cone air filter. Your choice of intake will also effect your exhaust's sound. I wouldn't oversize your exhaust too much or you may have problems related to your back-pressure since you already removed a huge (although purposeful) restriction from your system. Good luck!

EDIT: Note after re-read: A hollow cat and a glasspack is not going to be quiet under any circumstance, you may even get inspected over it depending on where you live.
