My Rendition of a Cross Flow Exhaust
LOL I never liked how all the other exhausts forced the two banks through the same size opening as the primary diameter of the one bank.

surely you didn't invent the x flow design, as a sponsor its common courtesy to not to be a "...." in other's threads

...Agreed and I have metioned that also in other threads..
I was looking at that design alot actually, and was not convinced it was worth the effort. I am however curious to know how a system with no x-over but the same length( bends that do not open in the middle) would sound.
I just know straight pipes don't sound good at any rpm. (the straight off the turbo to tip kind)
This design is closer to what I prefer too, I bet it will sound good.
Nice job.
