The Magnex was discontinued about 4 Years ago, but we were able to get Magnex to make them made in batches of 10, which we did. It may be possible to get them to do this again.
Unfortunately the call for these has declined, as more and more people who have Escort Cossies have already got stainlesses that last forever.
The magnex is a twin (side by side) system that is a little quieter than the Mongoose, which on big BHP means you are more likely to pass sound test at a track day. The magnex one is very similar to the original, splitting in 2 after the down pipe. It fits alot closer to the bottom of the car as it uses 2 small pipes rather than one big one.
