So I now have the feeling of a miss and a check engine light on. I head up to autzone for the free scan and it reads like it feels, misfire on number 1 and a bad CAT. Looks like the cat is so far gone its making the engine misfire.... So I run up to the exhaust shop to have them look at it and was keeping my fingures crossed for news of it being the rear CAT, but no dice. Its the front CAT and the direct fit into the manifold. I was not willing to pay the 500 for just the part from the shop thinking I have a welder and can weld fairly well. After looking under the truck I see that its a bolt in application. What are my options for this? Can I hollow it out, are their better aftermarket parts or at least cheaper than from kia of a shop? At this point all I know is I can get one for about 250 online but I am looking for all good options, any ideas would be very welcome. Thanks.
