    Hey guys second post here. I’m going to be changing my exhaust system finally. Currently I’m straight piped all the way to the headers (stock) and have no cat and still can’t backfire. I’m looking to get some headers, testpipe, and finish it all the way to the back. I’m a stock j30 v6 with just a aem cold air intake. Can anyone give some pointers on what I could do or what brand to get for headers, testpipe & piping? What size I should have the pipes done. Thank you all in advance for all you help.

    Hey did you ever figure it out? I’m actually in the same process now.

    It'll never do it unless you modify the fuel/spark
