: High Flow Cats???

05-01-08, 05:51 PM
I was telling my friend that I am going to replace the headers and do a full catback exhaust and he was telling me to make sure I put in high flow cats.. Anyone know if there is Escalade specific items on this or do they just use a universal one for the Escalade? Thanks

Cats are not specific for your vehicle. If you are going all out then yes include high flow cats but as soon as you move then from their stock location you are no longer emissions compliant. Your friend has the right idea but it is not necessary to go with high flow cats. The difference in flow is not significant, but in sound yes. Ideal situation is to find a header and intermediate pipe setup that will include the cats, then add you catback to that.

If you were going to heavily mod the engine high flow cats like from a company like http://www.randomtechnology.com/ would be the way to go, but with just some bolt ons the stock cats will be fine.
