Welcome aboard and congratulations for getting a Cougar with such low mileage on it, you have done well.
Meantime these are the website you need to save to your "favourites".
Modifying the exhaust is by far and away the best method of obtaining extra horsepower. Start with a 2.5 inch Cat-Back system from Trubendz and you will be amazed at the difference.

You can get a K&N pod filter from Ebay as these fit straight on and you can do it with a screwdriver = 5 h.p. not a lot but it sounds beastly.
The ultimate H.P. gain is the MSDS headers but would recommend you do this last.
Use Rockauto for all your parts and you will save yourself a lot of $$$.
Post some pics if you can...so we can all see your ride..
