Someone is making popcorn... in my cat!

So for the past few days I've had this increasingly unbearable exhaust noise. I swung by a local muffler shop to have the guy take a look at the brackets and he pointed out to me that the noise is coming from the cat, which has a loose part banging around inside.

So, I am now in the market for a high-flow cat and new muffler (why not?) and was hoping for some suggestions.

Alternative method - remove the cat, use a bar to beat the interior out of it, reinstall. Gain about 5 HP.

Still passes emissions and visual inspection, at least all of my Spiders did.

nearly impossible now to pass Calif emissions test with a cat that doesn't work; the standards are way too tight

I'm unfamiliar with a high flow cat. But I think the best suggestion I could make would be to find a new best friend who happens to own a muffler shop.

I've thought about gutting the cat, but unfortunately I don't have any flanges. I think the exhaust was replaced by the PO, everything is welded together.

I would go with a straight shot to a muffler, but unfortunately all the muffler shops around here are paranoid about getting in trouble, so they won't cut a cat out.

Ideally, I'd replace the cat with a high flow unit (so I can still pass smog) and an aftermarket muffler to make-a the vroom vroom music.

Think I found a good replacement...

Now I just need a glasspack...

you really don't need a high flow cat, your pipe dia is only about 1 3/4". You can get a replacement cat installed for about $125. With the cat in place, the sound will be quite muffled anyway so really no need to spend a fortune on a muff. I've run them with a cat, and just the front muff with a straight pipe out the back and they aren't that loud. You might even consider a glass pack to replace the rear muff. They're very cheap

I picked up a cat and glasspack muffler from summit. Grand total: $99.85 with 2 day air shipping. Not bad!

[nicktheviking]

Just got back from the muffler shop. Got a new cat and glasspack installed. WOW! Sounds beefy.

sounds like you're making good progress. Will we see you on Oct 4th for Cars and Coffee or at BFI in No?

Quite possibly. As long as my boss doesn't need me to come in!
