Race car sound? I think so!

EDIT:
You might even get pretty respectable afterfire! With barely any room to detonate dumped fuel before the exhaust exit, you'll get some nice flames (and likely cook your door panel, melt the paint, and possibly warp your pinch welds, unless you plate the area with some steel).
