Well it has been 5 years since I have owned a mustang and boy does it feel great to be back. I just picked up an 07 california special. I am however tying to figure out where to get the biggest bang for the buck. I already have an exhaust system thanks to a kid on craigslist selling an slp axle back for $150. However I really don't know where to go from here. I can't afford the big power adder at the moment and probably wont for some time. Do you guys have any suggestions to get me going? I have cruised many forums already and read a lot but I never had much luck with other mustang sites. The knowledge here always seems to be better. Thanks in advance for the recommendations!!
