Glass Pack for a resonator

[Smolck]

I saw the below video on youtube and love the sound. I think it is the same member trying to trade his alcantara for leather interior. Anyways, it says he used a glasspack for a resonator.

In thinking through how I am going to build my custom exhaust (now that the headers are done) I was curious, is this common practice?

I am trying to kill the rasp and get a deeper tone. Any thoughts? And would a glasspack in place of the stock 2nd resonator yield similar results with the stock muffler?

I am not sure about glass packs but when a friend of mine put on headers he installed some 100 cell race cats into section 1 to help with both the rasp and the smell. He said it was great. Sadly he sold the car before I got a chance to hear it.

Also thought of doing this, but I need to know how much POWA I will lose with cats. I won't sacrifice even 5hp for cats, I just won't.

I wouldn't for see much loss from race cats.

After looking at the pics you posted I bet most of your gained power came from eliminating the bottle kneck just before the cats versus the cats them selves.

I'd say that and the fact that I had about 30% flow through one cat and maybe 50% through the other was my biggest issue. My car had what would amount to an elephant on its chest. Problem is, I see no need to add the cats if they sap any power. The smell doesn't bother me enough to worry about it.

But it would be nice to clean it up a little so I don't kill some poor motorcyclist some day who follows too closely.

Exactly and if it helps with the rasp and smell at the same time then I would consider it killing two birds with one stone.

I think we need someone with some more exhaust experience to chime in.

I'd really like to know if the glass pack is in place of the stock resonators, or in addition to them.

So nobody has anything to add? Glasspacks? anyone?

No experience with them.

Never used them on this car buy I've used them on my 79 cutlass and 79 Malibu
