Had a boxster S come into the shop friday evening for some upgrades, and thought you all might want to see what is involved. I put on a B&M short throw, dansk muffler, fabspeed Secondary cat bypasses, GIAC flash, and evo cold air intake.....I forgot to take a few pictures along the way, but the bulk of it is there....All very DIY in a few hours, with the exception of the flash load....
