    i just installed my ebay header today.. they look pretty decent for being so cheap...no CEL so far. I have a RRM test pipe with the n1 cat right now but its seems a bit raspp in high rpms...what is a good way to get rid of the raspy-ness? I'm thinking about going with a obx high flow cat or maybe a resonator..suggestions?

    i dont have a video clip of the raspiness but im thinking a obx high flow cat might fix the problem..hopefully. i cant seem to find a bolt on resonator so its either stock cat/ hfc cat... i dont really mind loudness.. i just dont want the civic sound..

    the test pipe has no restriction so basically any kind of cat would be the way to go to reduce the raspiness whether its a stock cat or high flow cat. its all up to you on which cat you wanna use.

    i have the ebay headers n downpipe to, since mine is an 05' i have to have either a test pipe or cat fabricated to a certain length to bridge the gap where the stock cat should be. i havent installed everything yet but im going with a universal cat thats 2.25in piping since thats the diameter of the dp and later on imma have a 2.25in custom cat back fabricated as well. i didnt go with the high flow cat cause it was too expensive in my eyes for a simple cat and diameter is to big for the setup im going for

    Yeah that should still work out nicely.. now im runnin ebay headers/downpipe, with a OBX HFC, and the N1 catback..it soundss awesomee i like it. only problem is my check engine light is still on...i know RRM sells a CEL eliminator but has anyone every used it? and does it actually work?
