seen this on ebay - my question is regarding the psi increase - they're saying 2-4psi increase. Surely this isn't really a good thing to fit is it without an elec. boost controller fitted or something? has anyone got one fitted and are they any better with it?

The increase in boost is simply due to a removal of the restriction from the stock pipes. Obviously you will be better off with a tune, but it is perfectly fine to use with the stock ECU.

Some ppl on SAU have used them, with good results. There are split dumps available which will give slightly more power (due to less turbulence) but I used a combined one like the one available and it was definitely worth it.
