I've used a carsound cat for awhile, approx 2 years. When time comes, I'm thinking about just swapping my oem cat and stock muffler back onto the car. Can the cat and/or the muffler go bad? is there anyway to check it?

 

if the cat does go bad, your car will let you know with a nice little cel

 

if the cat starts scratching you...yes...it is considered bad.

 

Yep

 

Average lifespan of a cat is 15 years, right?

A catalyc convertor shouldn't go bad when stored properly. At least not worse than under the car.

 

Meaow

Edit: on a serious note, the cat or the muffler shouldnt go bad if not being used

 

A Cel should come on a bad cat.

Not sure if it's this way with the acuras, but my miata's cat is under warranty for 8years/80,000 miles.

I think it's an EPA thing, but I'm not too sure.

 

Hahaha...i know the "bad cat" is going to come up...

Thanks.

What is the proper way to store a cat and muffler?

 

To store a cat you can get one of those carrying boxes
