when we picked up this truck the stock exhaust was rotted out and we just had some tubing lying around that worked perfect for a side pipe wasn't planned just happened that way we originally wanted to run it out the back and use c5 corvette tips in the center. the 720 cable wasn't even close i think we got the cable from a conquest or dodge caravan i cant remember. its running dual plugs all the time. its a ton quicker than the L20b spins the tires through 3rd when you want it too
