June 27, 201214 yr Ordered this yesterday and it came this morning. My bike was already at the workshop so I dropped proper work and fitted it. Mega light compared to the standard lump of iron, The welds were very neat and it fitted a treat. I had to flush it out with some thinners before fitting as there was alot of swarf in it and was stuck to the inside. This was due to it being oiled to protect it in storage I suppose. It is a sorter bend than the standard pipe and is of the conical design. Inside the pipe, if you run your finger inside it (it was my finger Honest!!!) You can feel its quite sharp at the inside of the joins as the welding has not penetrated through. I have never handled an arrorw or s3 pipe so I don't know if they are the same. I would imagine it would need to be smooth inside for performane and to stop carbon building up the manufactures may know something I don't. I took it for a good ride round my farm industrial estate. Anyway it has that factory sound to it, Not noisier but you can hear it ping with every stroke and the performance is slightly sharper off the bottom and the bike seems to rev freely. I feel it has made a noticeable difference, The bike is a 09 300 with a high comp head and Carbon tech Boysen reeds so it's very naughty in the power department to start with. I paid 180 for it. Does it give 180's worth of performance? NO Does it give 180's worth of shiny factor & sound? Hell Yeah. Overall Im happy with it, I chose it because it looked pretty, was 20 cheaper than the S3 and it boasted the conical design what ever that really does but I have an idea of the theory behind it.
