I have the dual flex joint and was going to use it. I decided on Maik's collector because it helps with clearance in my Syncro and it is sturdier.   It's a compromise.  

I won't dyno the setup but will take before and after timed runs (30-50) and report the difference.

>> Speaking of scope creep. Look into AEG exhaust manifold. With minor clearancing it mounts to a 1.8 head. I had a collector made by Maik Jankord.  Using 2.5 inch pipe with two flex joints. I will install it this fall. It beats the standard toilet bowl collector I currently have.
