was gonna say the same thing, When correctly done, You can see Huge results on a forced induction engine. You can see first hand on the E55 forum, a member there opened a set of factory manifolds and the internal pipe is like 1.25in! Crazy! So thats one reason headers and a larger diameter mid pipes can yield 50+ HP on those. I bet it would be around the same or just a bit less on a modified 32 or SRT.
