I just cant understand why you'd want to "make shit" in that nice looking trunk?

Well I am playing with some things. First I wanted to get the exhaust over
the suspension so I can increase the volume. I did not want 180's because
I may want to come up with a make shit trunk at some point.

180's are awesome as you can pair the correct cylinder which is something
you can never do with a right L/R system due to the firing order.

I originally built these to go over the suspension but the firing
order/back pressure left every other cyl lean:

You can never get an optimum system with the firing order so what I
decided to do, since this was an engine based on lots of torq I decided to
run each primary to the rear and collect them as far down as I could.

The butterfly is just so I can play with back pressure.

I can't wait to hear it on the car. On the stand the sound is fantastic
and I think it has to do with being in earshot of each cyl exit in the
can.
