the shifters are junk. they are hard to get into reverse sometimes because of it. i took out the rubber bushing and made some derlin bushings to replace it with. it helped but she really needs a shifter.
i built her a cat-back last year for x-mas, used 2 hooker areo chambers and a C6 X-pipe. i looked for a few days before i bought the mufflers and nobody has hookers on their V. its not too loud but everyone tells her how awesome it sounds. and a tune, thats all.
