Have you considered running a straight pipe (or glasspack muffler) in place of your stock one? It would save some weight, probably some engine efficiency, and would make it MUCH easier to design a rear undertray because of the reduced space. You could probably do it for under 30 bucks for all your parts. I know finding somewhere to do it is a problem, but it might be worth it in the future. In general I think you might be near law of diminishing returns in terms of aero, and the engine might be your next step. What that specific engine benefits from is outside my area of knowledge though.


Otherwise, really great job. I love how full-on you've gone and it looks something bordering on cool with the new paint job.
