Catalytic Converters

Does it matter what Catalytic converters you use? I was just gonna go with a pair of Magnaflow Cats from summit. Im not looking for something thats real expensive. Trying to keep them under $100 each.

Re: Catalytic Converters

I did 2 3" magnaflows for mine. I dont have any real emissions testing though either.

Re: Catalytic Converters

Go to your local non-national chain muffler shop and see what they offer in high flows

Re: Catalytic Converters

When I had my TPI truck, I used a cheap summit 2.5 inch dual in, dual out cat. That way, I didn't have to run an X pipe.
