Default need to replace drivers side cat?

brought my car to the exhaust place because i need my drivers side cat replaced and they said $300, because they need to order another stock one because the 3 bolt flange. Is it possible to weld in a high flow cat there without moving the spot of the cat? or do i need to replace it with a stock one? thanks

how many miles are on the car? As long as its less than 8 years old and under 80,000 miles, its covered under GM's warranty. I just had both cats on my 02 Z28 replaced for free.

They extended the warranty to 10 years / 120K miles on the cats.

I'm confused - sig also says Flowmaster+high flow cats....

The 10year/120K extended GM warranty is only on the 00-02 cars.

An exhaust shop should be able to adapt a hi-flow cat in there.

Hmm, my dealership said my 2000 only had 8 year 80k when they replaced the cat yesterday. Ill have to ask them about it if (when) the drivers side goes out.

Default cat

a good muffler shop should be able to repalce it with a high flow may have to take it off to do so, is the drivers side the one thats real close to the manifold?

Exhaust shop should be able to adapt a cat on there for you, or try ebay, they always have stock cats listed for sale.
I have the ones off my car sitting in the garage, if you want to buy it let me know.
Either way, good luck.
