you can get some pvc that will work. but goto a muffler shop ask for some scrap 2-2.25" exhaust tubes, bet they let you have them free, or go with a 10$ case of beer , bet you can even have them custom stretch bend them for yah , im talking a local lil muffler shop
rednecks will wonder what you are up to and prolly help out. they did here they made a bunch of bends then gave them to me free just cause they were interrested in my project.
couplers, get some 2.5" or so radiator hose from a auto shop, or truck suplier. works well, dont use the crap from homedepot or lows the plumbing couplers will melt and rupture under stock boost!
rember big rigs have alot of stuff you can scavange in turbo projects
