Hi Guys, Just wanted to mention that there is a GP on the SLP Long Tube Headers at TT performance that ends on the 19th of December. It is a Pretty good price at only $629.00 plus the install kit and cats. I am only getting the headers and install kit because I was able to get my hands on the race pipes that are now discontinued. This is a good way to keep the cost down a bit if you get the race pipes and cats in stages. I do believe that a sponsor on LS1.com is making some race pipes that will be compatible with the LT's. Thanks alot, Dave
