I have catless headers on the way from calico coatings. Its their a high-performance Black Series ceramic coating , good to about 2000 degrees.I am going to add some high performance catalytic converters downline at some point. Those high performance headers with the built-in catalytic converters look pretty sweet.if you compare those to the stock headers they definitely look like they will flow better. They should fit just fine with the exception of a modification to the mid pipe. It needs to be lengthened an inch or two. As far as a cel light, there are a few ways around it if you do run catless. I have a shark injector already, but I dont think it has the test pipe tune.... It can be added it think. Active autoworkers might be the best option. I'll have my headers on in about two weeks.
