Exhaust, but more importantly the gauges you'll need like EGT, oil pressure and boost gauge. The gauges can be added just prior to the SC installation, but a good exhaust system should be in place when the SC is ready to be installed.UsedtodriveaTahoe said:I am thinking I will eventually go JRSC...what mods need to be done ahead of time?

Limited Slip Differential...it basically transfers power to both wheels. w/out lsd...one tire is grabbing traction while the other is just spinning...like a stock rsx.UsedtodriveaTahoe said:What is an LSD??:dontknow:
