Since you have to use a catalytic converter anyhow, you might as well use one that will last a long time and will maintain your vehicle's performance level in the process. Walker direct fit catalytic converters not only outflow stock converters, but they also feature aluminized steel heat shields (many have dual shields), 409 stainless steel shells, 16-gauge stainless steel pipes and nipples, and a heat-resistant sealed mat, all of which help them last longer. These units are direct replacements for OE converters and will install with little or no modification. Some converters have steel air tubes with perforated holes to help distribute the airflow evenly, without robbing power. New flanges are included when necessary.

Catalytic converter

Summit RacingSummit Racing Verified Purchase

I bought this catalytic converter for my 2000 chevy silverado. The product was shipped in 2 days and i did not pay for the shipping and handling. The part was a perfect fit, no cutting or adjustments needed to be made. Best thing i did was put wd-40 on the nuts on all three connection flanges a week before i got ready to change the cats out. It made taking the nuts off very easy. It only comes with one ceramic gasket for your left side coming off the manifold to the cat. The right side does have a donut gasket that is not included in the purchase. I had to go to my local auto parts store to buy this gasket which only cost me 6 bucks. But thats why i gave this ratong 4/5 because i had to go amd buy this one gasket. If it were included in with this set. I would not have had to go to the store. Also i did buy 4 new o2 sensors at another site for te sake of having all brand new ones and not having to buy them later on if they failed. Overall im very happy with the purchase. Just that one gasket that imo should come with the cats since the ceramic gasket comes with it. ...read more

Direct fit, cat system

Summit RacingSummit Racing Verified Purchase

Thank you Summit for your knowledgeable staff, fast service/ shipping and for offering such great product at an affordable price! After fighting with the dealership on MANY fuel system issues, I finally had to take matters into my own hands. Using a code reader, and some knowledgeable tech's from another dealership, I was able to track down my issues under the hood, which included replacing at least the bank one cat, and now the 04' Sierra runs like new. THANK YOU! ...read more
