What do you make of this? -

Obviously only for cars that are out of warranty - http://fuelcat.co.uk/DieselBoost.html

Out of interest, when is a new car out of warranty.

I want to put a powerflow exhaust on my car

Seen these before on petrol cars which increase the octane and they are ok, but not needed on modern cars IMO. Work better on the older diesel engines.

Modern cars the ECU controls it alot more finely, compared to older diesels which used to smoke a bit.

Fit one and it just voids the warranty on the exhaust system the way warranties work now.

how do these things work then? is it like a fuel filter or something?

It can void the warrenty on other connected parts as well as just the exhaust, so make sure you get it done right.
