I hope to get it Autotapped this weekend if I get my car put back together. I sold my FLP kit, bought a set of stainless steel 1 3/4 Kooks, Dr. Gas X-junciton, and 2 Dynomax bullets. Im waiting for all of it to show up to my house as I type. Once it comes in, I will install the headers, take it down to the muffler shop, and have the true duals built. I was suppose to have done this a long time ago, but the parts are taking longer than expected. A local board member on here kindly offered to help me out, thankfully! But I will let you know as well as others how it turns out. In a way, I kinda hope there is something going wrong when I get it scanned because Ive dumped a whole lot of money into this car and its not putting the numbers as I was hoping. Are the Z28 springs any different than the SS? Also, my SS didnt come with any SLP options, so if there are upgraded springs for the SS, I dont have them, theyre just the plain SS springs.
