For the JWT 500s you stated you had in the other thread, I'd say go with at least a 3" pipe size.
What size turbos do you have?Spongerider said:2.5", remember there is only 3 cylinders per pipe (V6).
I personally think 3" would eliminate some problems in the future, but to each their own, I suppose. No such thing as having too big an exhaust on a turbo car (Within reason, of course).Spongerider said:Stock. My friend is running a simular setup with TD05-18g (622rwhp)
