T/A has FIPK, MAF, T/B, intake, LT's, ORY, cat back, 9", shifter, D&S C5 brakes and wheels, front and rear sway bars, lowered and lower rear control arms. I also have LCR brackets but I have yet to install them. I drive it all year as long as there isn't too much snow on the roads. It still gets around 20 MPG which is about 4 MPG better than the Trailblazer.
