    SFC strengthen the chassis, prevent flexing, and keep the car straight during launching.
    As far as catbacks and mufflers, depends on what sound you want. Apparently, most people don't like the sound of LT's and LM2 combination. But check out www.ls1sounds.com for sound clips of different setups.
