exhaust

[carnut4real]

I want to run 3 inch exhaust off my headers and dump off behind the cab,but I'm not having any luck finding anybody that sells a 3-inch for a c10 anyone know of anyone who sells a kit.I also need to do something different with my stock clutch fan and I've seen people saying they got rid of the electric fans and went back to a clutch fan and so on and so on, but my new engine is still running warm with no thermostat, so I figure good start is to open up the exhaust, that may do it but looking for feedback on the fan also
