I have just been sent this as a result of an enquiry I made. Anyone got and BTDT with the boost valve and do you think the hi-flow cat assembly sounds expensive? 
Cheers,
Steve

Hi Steve,
We offer a cat back system for your S2 with twin front pipe, centre section and rear silencer. We also offer a large bore downpipe and hi-flow cat assembly.
The system features 2.50 pipework, twin 76.2mm tailpipes and is priced at £523.64
The hi-flow cat assembly is priced at £793.13
It may be of interest that as well as exhaust products we also offer a range of Hyperboost valves which are proven to reduce turbo lag and improve throttle response over the OEM diverter valve. These are priced at £111.63
All our prices include VAT and free delivery within mainland UK

Cheers,
Steve
