Ok i decided that i wanted to upgrade my struts and shocks, because my front mount broke. I like the ride of the stock suspension, but i do not like the idea paying for new stock suspension when i could upgrade to aftermarket for same price. I have narrowed it down to Bilstein PSS Coil-Over Kit setting at stock height, or just a koni FSD or Bilstein strut and shock with original springs. Also, i have decided to upgrade to a aftermarket exhaust and was thinking about a borla exhaust, but i came across a deal on a magnaflow. if anyone has info or comments that could help me out i would appreciate it, thanks
