The main tells are the exhaust and the badges. Get rid of the GXP badges and have some custom exhaust work done.
In my previous life I was street racer ( before kids )
I had my real exhaust pipes dump before the rear wheels ( not visible ) - and had a dummy single pipe hanging out the back.
You could also do a large diam. single exhaust - with a cut-out that opens before the muffler.
Good luck !!!
