S2000 exhaust modification

I thought I'd post this mod I had done to my S2000. This was dreamed up by the UK guys over at s2ki.com and was born out of the desire to make the car sound more fruity without the awful droning caused by an aftermarket system.
Essentially, a pipe is inserted which allows a fair amount of the exhaust gasses to bypass the rear silencers.

The mod was done for me by Ray and Ang up at Daytona Autos. I think it sounds pretty good.

Haha, I have no idea what the deal is with the related videos.
Yeah, it's a bit bodgey but people have tried many different systems and only the single exit ones seem to have no boom. All the dual exit ones drone like mad.

Yeah, it probably drops a few bhp off the top. Not fussed really as I like the sound.
The pipe that goes through the silencer is an S shape. We're bypassing 2 of the bends.

Here's a cut away of an S2000 silencer

I don't remember to be honest. It was a little smaller than the diameter of the original pipework. 40mm seems to ring a bell.

I had to watch it again. It was 3.5 years ago. My ex filmed it IIRC.
