Sports exhausts sound good, but in some cases can actually reduce the power of the car due to not providing the required back pressure.
Not sure what sort of budget you have in mind, but any cash would prob be best spent on making sure the car is set up right, ie rolling road session. Brake and suspension upgrades will also improve your car's performance, however the best thing to start with is the driver - I found that half a day's Ride Drive session with Madcop made the car a lot faster

It's quick, it's free, and it's easy. I assume you have the 2.9 V6.
1. Duct cold air to the air filter. (As much as you can. It should be good for a few bhp and made a difference to mine).
2. Prise the black plastic tops off both air flow meters and relax the springs by a couple of notches on the round spigot thingys. (This allows the the AFM vane to open easier and tells the ECU to fire the injectors earlier and therefore for slightly longer which will get more fuel into the engine).
3. Use Optimax.

I think I've achieved this by accident and it may work!
To get better access to work under the bonnet I ran the front wheels up on to a 2" high plank, this enabled the bonnet to move well forward but at the same time it must have pulled off the 2" (ish)flexible air tube to the passenger side of the car, this has left a very nice 2" fresh air plenum inlet box from low level that is almost opposite the air filter. The original pipe I have simply strapped adjacent to where it should be. Does this sound sensible or should I put it back together again?

John Mac,
Sounds okay as it is to me.
SIMON67,
I'm going from memory here, as I did the airflow meters on my car a couple of years ago and it's a bit vague now but i'll give it a go anyhow:-
Under the black plastic tops there is a black round disc with letters beside little slots all around the disc. In the centre I think there is a coil spring with one end clipped into one of the slots on the lettered disc. Using pliers, gently remove the end of the spring from the slot in the disc and put it back in another slot where there is less tension on the spring, (i.e back the spring tension off 5 or 6 slots or until you can feel that there is still enough tension in the spring to operate the vane).
As I have said, my memory is vague but hopefully some of this makes sense with what you see in front of you.

I have backed them both back to the point where they close fully when inverted i.e. there is the weight of the vanes trying to open them. This has given me a datum point so that I can achieve some kind of ballance. I guess that I will have to make some adjustments once I have tried a drive tomorrow.
