I've just had a SuperSprint cat-back system installed on my car and I love it! Zero drone and not too loud but when you floor it it opens up and sounds sensational!
The SS headers (which I wanted badly) are a promised 10kw-15kw improvement, but they only fit LHD cars - but, they can be modified to fit a RHD car, but at $6k, I'm not going to pay for the R&D!
If anyone knows of any other header systems for the R36 I'd love to hear about it!
