Homemade Turboback Exhauist

[flip888]

I was just wondering how hard it would be for me to make my own turboback for a 92' eclipse GSX if i already have all the piping and a welder.

do you have a pipe bender?? if you do, and know how to use it, it should be very easy, and cheap.

I dont have a pipe bender but the shop that i got the pipeing from sayd they would give me some pre-bent pipes that they have laying around that i thought i could weld to the pipes i already have.

And i wanted to ask if i could cut the pipes at angles and then weld them together. For example if i wanted a 90 dagree bend, could i cut both the pipes at 45 dagree angles and then weld them to eachother?
How would that compair to a mandral bent exhaust?

Try this with a garden hose... Lay the hose out with a series of nice smooth bends, something like you would see with a mandrel bent exhaust system... Turn on the water and note what kind of flow you get.
Now, re-do your layout with a series of 90* bends similar to what you are suggesting with your cut and welded bends. Turn on the water and note what kind of flow you get.
Give us a report back after you do this...

What kind of welder? I weld exhaust systems all the time, whether its from scratch, or from a kit, they are all the same and easy. But dont try and balogne cut it to avoid bends.
