first off dude you bought an audi... upgrades are expensive. on the low end if you get a chip and intake, your cash is gone. then there's the issue of actually upgrading a rental. unless you plan on keeping it or hawking the parts afterwords, theyres no real point. i dont know what the rules are in georga, but bc your car is turbo, you want to start with the back and work forward. its exhaust drivin so after the exhaust has done its job, get rid of it as fast as possible. test pipe if possible, or high flow cat and exhaust if not. in the best conditions, dumping the exhaust just after the turbo is ideal, but emmissions are dumb. the best bang for your buck is a chip. youll feel an amazing diffrence, but that soon ends when your stock recerk valve blows up and your running on 90hp and in vaccum. i think apr sells a forged one on their site. otherwise intake is nice but not really a big issue unless you go to a front mount intercooler where you can then take advantage of a cold air intake. also a super cheap and amazing mod is exhaust wrapping everything in your engine bay and on down to the first hanger in your exhaust. youll notice a diffrence with your spool time. as for warrenty, as long as they cant prove that one of your modifications caused whatever the problem is, your still fully covered. you putting on an intake and then your turbo blowing up are unrelated. you installing an exhaust and one of the o2 sensors being damaged in the process is your bad. 300hp at the wheels is easy with intake, exhaust and a remaped ecu so have at it dude.
