The throttle body is a 70 mm aftermarket for a 302 Mustang. The outer tubes will hopefully benefit from some dynamic wave swapping, but the inner tubes are strictly for momentum. Like Ed's, it is really snappy on the throttle now, like a hot rod. It also runs smoother than before.
I did much of the TIG welding myself (don't laugh, I'm just a beginner). It's all part of the "educational" aspect of experimental aircraft! I mention this, because the slight bends in the outer tubes look terrible from the outside. They are really quite smooth on the inner (important) side.
