i figured it would be nice to create a thread where people can have access to places where they can get materials and such for fabrication. if a mod wants to sticky this i guess it will be cool so ill start off with a couple...

http://www.mcmaster.com/ <-good site for pipes of different types. look under 'Pipe and Pipe Fittings'

http://www.onlinemetals.com/ <-another source for various types of metals

http://www.chassisshop.com/ <-yet another source for pipes and various other pieces that one may use for building a vehicle.

http://www.kteller.com/ <-more pipes (in exhaust section)

http://www.atpturbo.com/ <-these guys have all sorts of stuff one may find useful in creating a turbo setup (flanges, fittings, pipes, couplers, etc)

http://www.roadraceengineering.com/h...eekerparts.htm <- several different things, but mainly cheap flanges
