New Glass Pack Mufflers from Magnaflow

New Product: MagnaFlow Announces New Glass Pack Mufflers

There are a few phrases in the world of exhaust systems that automatically conjure up the “I want to go fast and I don’t care how loud” image. They are:

• “straight pipe”
• “cut-outs” and
• “glass packs”

I’ve never thought of a glass pack as a particularly good thing. First of all, they’re notoriously cheap. They don’t do much in the way of “muffling” and the popular perception is that the fiberglass packed stuffing inside them (hence the name “glass pack”) is only going to burn-up and/or blow out.

However, when Magnaflow starts offering glass packs, you sort of have to pay attention.

Magnaflow’s newest offering is a glass pack muffler that’s available in a few sizes (smaller barrel = louder muffler), and they’re using something called “rockwool packing” that seems to be a durable sound deadening material that won’t burn out or blow out.

However, I’m just not a believer. First of all, glass packs are notorious for changing sound after a few hundred miles – I don’t know that these Magnaflows would be any different. There’s also the fact that Magnaflow’s Rockwool seems just as likely to burn up and blow out at some point as all the other glass packs before them. Check this out:

While I’m not saying that these Magnalflow Glass Packs aren’t a decent product – I haven’t tested them so I just don’t know – I think they pros and cons break down like this:

• Pro: Cheap
• Con: Cheap
• Pro: Loud
• Con: Loud
• Con: Probably going to burn out or blow out eventually, and then you’ll need to buy some more

If you want a cheap, loud muffler, this is just as good of an option as anything else (maybe better – Magnaflow’s stuff is usually very good). However, if you want a good muffler, a glass pack muffler seems like a stretch.
