GMC Sierra C3 Questions

If there is anyone out there who has a stock exhaust system and could send me some pic's. I got the truck and was going to put an exhaust on it and the original owner cut it all up and welded a very bad job. This would be very heplful.

What is making my driver and passenger side floor boards wet?

When turning at low speed, as in a parking lot, the front seems to "crab".

The aerodynamic headlights do not proved much light when doing night traveling. The 6.0 V8 engine always has 'piston slap' upon cold-starts making the vehicle sound like a diesel engine. Truck is very reliable and loaded with too many options to discuss. I would buy it all over again if given the chance.
