I picked up some Magnaflow Mufflers today at Pick-n-Pull from an 89 GTU. Were only 8 bucks each.

How do I tell if they are the Stainless type, Racing, or other? Or if they're even still good?

Also, there's quite a bit of carbon buildup on the inner tips...can I or should I attempt to clean these up?

They were cheap....is it worth replacing my stock muffler by putting these on until I buy others?

Whats your recommendation?

I'd pick em up for that price, um, btw, they will eventually all have carbon buildup in em.

stainless is not magnetic

I'll try the magnet test...

Is this an improvement to the stock exhaust...used etc? I currently have almost no mods... did the Icemark AirFilter 1" hole trick....that's it so far.

Racing Magnaflow...I don't know...just read that in a bunch of threads. Sounded like they offered many different types. Going to Magnaflow's website to understand this better...if they've got one.

It looks more like a stock replcement... bosal/borla makes a stock replacement, they are a big time muffler company just like magnaflow.
