To suit Yamaha R1 5VY (2004-2006) engine.
Came off my Caterham. Main reason for me changing it was that it now runs a Rotrex supercharger and so the manifold was thought to be holding back the power a touch. Obviously fine for an NA car.
I'd imagine it would suit most similar sevenesque cars.
1.5" diam manifold pipes, 2.25" after the 4:1 and the tail pipe.
Silencer is 6" diam and approx 2' long.
The photos make it look a bit crusty but it would clean up fairly well I think and the can is repackable.
£250 (new system cost many times that!)
Ideally collect from Rugby due to the size but I can post for maybe £20?
