I am going to replace cats on my car it came stock with dual cats. Think I am goinng to go with Catco cats. I called Summit Racing and they said I would use part#6005 2.25 inlet and outlet. But would like to use 2.50 inlet and outlet #6006. Went to discountconverter.com to check prices and then I see the 6000 series cats but scroll down and see 2600 series cats which say High Flow then I would use #2606 but cat is 16.5 inches compared to other which is 14 inches. Anyone know what the difference is between these cats I thought all Catco Cats were high flow. Thanks for any info.

I ordered mine through Summit, 2.5" in/out, can't remember the PN though. I got the universal ones as opposed to the direct fit...much cheaper
