100% the factory original 16v cars came with twin stainless steel tip pipes, I removed mine about 5 years ago, it had the VW logo embossed into it... The tips were 2inch diameter iirc
My Jetex system was the closest I could get to OE, looks fine, fits well, and isn't too noisy

Do you happen to have the 2 box system or the 3 box system?
My Jetex is the 2 box system...
This pic was taken about 7 years ago, and shows the Factory fitted system, and when I say factory fitted, I mean it! there was no join in this system over the rear axle, so it was fitted before the rear axle was fitted in 1989! Thats not bad going! although the car had only done around 60k iirc at the time...

This is my Jetex system, just a nice alternative to the OE system really
