Now just before I cop any flame, I generally cringe at the thought of anything off eBay being fitted to my car - I have though been looking at some of the silicon Y pipes off eBay and noticed that some of them are 1/3 - 1/2 the price of the Samco kits.

Some are 'claimed' to be close to the specs of the Samco kits.

The one in particular I've been looking at is the ASI Performance - I'd also bet my badge that these are a cheap Chinese make, but if they are indeed 3 ply (4mm thick) they could possible be worth a go?

Purely for the silicon Y pipe and not the intake pre turbo.
