i'm looking for a place that sells a diy ram horn turbo kit that'll sell me the piping and flange so i can weld it together. the ram horn designs won't work on my setup so i'd like to weld it to the design i need it to be for an h23 exhaust flange and a t3/t4 exhaust turbo flange.

 

Stop wasting your time trying to find a kit like that. Go to an exhaust shop and get what you want custom made. Even if you get what you need, what you want to do is very intricate and involved, unless your a pro with a welder... Forget it.
