Exhaust-Welding Stainless Steel

Just starting to look into exhaust systems and having a relative in the industry I think making my own system might prove to be a super cheap option. Was thinking of a 2.5" stainless steel system with a 16" race bullet and a 14" muffler.
Can my existing Lincoln Electric 180 MIG welder weld stainless steel? What would I need to change for success (gas, weld wire etc )???
Has anybody had experience with taking pipe from home to an exhaust shop to get it bent to the correct shapes? Will they do it are just tell you to GF'd?
Cheers
PS - i hate trying to get wings to fit correctly
