Glass Packs

Does anybody know if you lose performance, adding a Glass pack? I know that it quiets down the exhaust system which is good, but as far as performance what would I lose/gain? I'd call my local muffler shop, but I think they'd just jerk me around just so I'd buy one. So I thought I'd ask here first.

Hmmm, nobody has responded yet.

OK, where are you planning on installing the glasspack and why? You haven't provided enough information to give you a good answer.

I was planning on adding the Glass pack somewhere between the Cat. and the muffler. I have an aftermarket muffler and it's pretty loud. I heard the glass pack would quiet my car down, but would I lose any power or gain any?

It should quite the exhaust nicely. You shouldn't lose enough power to even measure.

Get one. :)
