Straight through cats by Magnaflow!
 

I like that it looks like a cat and not a test pipe

I'd like to see the data, I doubt you'd pass emissions. But here I just got a 200 cell metal core cat...

How the hell is that supposed to clean your exhaust?

Wold you mind asking your sister if she's seen my wallet? I have the feeling I may have left it on her dresser last night.

Exhaust will flow in and out of the active material with each pulse - that's how the silencing works in straight through exhausts.

Looks like a 'rally cat.' Back in the day, certain Rally rules dictated the use of cats. To ensure you didn't just wrap a heatshield around a testpipe, during tech they'd measure your exhaust temperature at both ends of the cat. It had to be hotter on the outlet side.

So somebody got clever and dipped a testpipe into a catalyst wash. It produced just enough heat to be legal.

This Carsound cat looks like the same idea.

I've got the ebay one and it works great.

Hurm, might have the solution for my updated build.

Thanks :)

lol@Joe fornicating with your sister. She's a whore.
