Mine are handed, 2005. The rear pipes did change but not clear when. The S1 Roadster has tailpipes with a baffle tube inside.
My Roadster came with a sports exhaust, and that had open rear pipes, and brackets which bolted around the outside. Nowhere near as tidy as the original tailpipes.
I set my rear pipes mid way between the chassis and tyres. I also applied insulated weave the full length of the car around the fuel pipes.
