might be new exhaust
IRL in your drawing there would be a muffler somewhere in there (id assume not a stock one considering how you drew the inlet). I see this causing a 'rat tail' appearance, the exhaust would either hang too low overall, or itd come down where the stock I pipe does over the axle, then hood right into a bullet or something, then left to the y and out tips.. i just dont think itd cut it.
