Check out Austin Racing's page as they now list a couple of interesting options: 1) an end can only 2) a decat pipe that can work with the standard or temi silencers 3) a full system Good to see the market is starting to open up with other non-termi options.
I am a big fan of Austin Racing products but the prices are silly now and they missed a trick designing this system. The main gripe is that link pipe outside of the swinging arm yet their system has not routed the link pipe behind the swinging arm. At £2400 that’s a fortune for no visual improvement. The slip on isn’t great, a bit of pipe and a silencer for £1440 ! Plus you will melt your boots on it. I got my full Termi system for not a fortune more than that and it retains the warranty.
Not a fan of either, especially the expensive one, looks worse than the OE (in my opinion), which is quite an achievement!
