Has anyone purchased and installed Warpspeeds Metallic Substrate Catalytic Converter . Wanted to get some opinions if possible from anyone with it installed.

 

just get a carsound cat from budgetexhaust.com, it's $90...

 

Just gut the inside of your stock cat. It does the same thing

 

Don't gut it, that's the dumbest thing you could do. Search and you'll see what I mean...

 

I was kidding, but ok. I would never gut it.

 

The metallic substrate cat is definitely a good upgrade. Go to the warpspeed site for more info. It looks like the stock ceramic brick, but the material is a lot thinner, so the air holes through it are larger... and it flows better. It's also supposed to be more durable since the stock ceramic material is hard and brittle.

If I had to replace the cat on my car, it's probably what I'd get. But I'm not in any hurry.

Good Luck!
