Gen II Side pipes

[heatandair]

I recently converted my 01 GTS to side pipes. I was wondering what people that have made this conversion have done w/ the stock exhaust exit in the rear bumper. I don’t like the hole and was wondering how to fill it and or make it look better.

So you have have the covers only w/o sidepipes? The Prototype GTS actually had the covers only with rear exh. like you.
They just put on some type of metal cover plates w/bolts of some type-one of the early posters has a picture of it also.

It makes a perfect flow port for your differential cooler. Later I added a trailer hitch there so I could haul tires and tools to the track and had the setrab unit laid flush. Put a metal surround around it a la Hennessey and it cleans up a bit. I suppose you could fill it with metal grating if you don't plan to use it for anything.
