I just purchased my 2006 s40 Volvo on 3/25/06 and I was looking at not only improving performance of my vehicle as in added horse power but I am looking to improve the fuel efficiency of that vehicle.

I would like to do anything that is within the bounds of the warranty and are not bank breaking? What do you have...let me know what suggestions you have.

Thanks in advance

As for fuel economy, I know Tech does not reccomend the Tornado because things can break off of it, but I know a guy that swears by it. Personally, wont put on in my car.

I have the Evolve downpipe and exhaust and love it. Plan on getting the ECU before the summer. As for the warranty, as long as the aftermaket parts arent the cause of the problem, the repairs are supposed to be covered by warranty. Furthermore, if u by from a reputable company, they will have their own warranty for their own parts.

those tornado things are junk.

SpankJunkie,

Are you a *BLINK*BLINK* person, or are you a POWER-crazee one?

There's enough in the aftermarket world for BOTH...
