Hi, I have a brand new Raceco large silencer still in box unused. This was for my R400, but now sold. I'll add in a used 4:1 collector to make the system complete Fantastic aid to reduce noise on trackdays from your R300/400/500. Pic with car is to show size..thats not the actual exhaust being offered Price: £650 ono including collector. There is no CAT in this exhaust for maximum air flow and performance. Will post in UK for around £40 (will confirm actual cost), or can collect from South Oxfordshire. Check details out on Raceco website and price >£800 (excluding the collector, which from CC is around £300 !)
