Turbo flange and down pipe?

[erikv11]

The word is indeed that angled flange turbo outlet flows the best which is consistent with what you'd expect by looking at them all side by side. I haven't messed with them myself just telling you what i've read. I don't know that you get more hp but you might get less boost spike due to reduced back pressure. I would expect you need a tune matched to get the absolute most out of the turbo outlet type. Conical I would get rid of if you can but your car should have a straight flanged outlet. It's probably not a big return on investment to go to angled if you're already set up with straight. On the other hand if you're getting a downpipe and are obsessed with doing it right then why not go with angled flange outlet and then tune it to match.

Thank you for clearing that up, I'm going to be doing a 5 speed swap(got the flashing arrow of death) in the next month or two so I'll be doing the exhaust while everything is open, and figured why not do header and down pipe. I hate tearing shit apart more than once to do things that are near by. I try to be as efficient as possible, when possible of course.
