I cant imagine a universal "piping kit" being much good. I build all my stuff in my shop on my mandral bender. It ussually takes 3 or 4 trys to get to a usable production piece. The first 2 or 3 have cuts, splices etc etc.....The fox body swap is pretty popular though. If I had a car available I d look into doing a production kit for sure.

I think your only real hope is a whole pile of pipe and a lot of determination on your part with a welder or find some local shop with the ability.

I buy 180* mandrel bends from Verocious and cut what I need out of that. They also sell donuts if you need a tighter bend radius.

Not everyone has a mandrel bender at their disposal. The prebent kits are awesome for the price and you always have extra left over just in case. Id say the cold side piping was one of the easiest things I have done on the car in relation to my turbo setup.

Id do it myself if I had the bender to bend pipe but i do not.

I just looked up columbia river mandrel bending and yes that seems like a very good choice if you ask me.

16 ga. steel is great if you have a welder as you wont have to use 12 silicone couplers, you'll need to crimp the ends as well. if you dont weld, use AL.

All you really need are 180* bends - IMO, it doesn't make sense to buy a single 45 or 90* bend when you can get multiple of those cut from a single 180*. I used 16 gauge mild steel 2.5"/3" from Columbia River.

Take your time and calculate your angles and you'll be good. Weld it in place if possible - it'll bend and change the geometry if you try welding it all on the bench. I found that out the hard way the first time.

EDIT...are you talking about hot or cold plumbing? I bought a CXRacing 3" aluminized kit for my cold side with various bends.

I have bought a couple of the universal kits from ebay. It is a LOT of pipe for the money, and the couplers and t-clamps are actually decent quality. Of course I cut them up and weld them together myself, so don't expect them to fit together without cutting and modifying.

if you're worried about weight use 16ga AL.

We use them also and have had great luck. If you get any flex couplers, get the good vibrant ones!
