MPC Street Funnies

[Oldschool4x4]

Have a question about the street funnies series, it has to do with the Zoomie headers, from pictures I've located on the web, I see no way that they actually hook up to the engine and stick out under the doors. So question is, do they in anyway hook into the exhaust system or, are they just glued to the floor board? I have some older MPC kits that I want to build as street funnies.

Thanks
