$tealin is not worth it. JWT POP worth the price if you can find one used. Hot shot been reguarded as one of the best fitting. Place Racing was the first on market. AEM has a new one thats susposed to be bad ass, only one example seen so far.
Courtsey sells a good one. Think the pacesetter is adjustable. I forget tho, me not a manual driver
Its personal tastes, probaly a custom job if you can find someone to piece together one with manderal bends or can manderal it themselves with a mangaflow muffler and pre muffler/sliencer. Courtsey's is decent, but a big tip. Most have huge tips. Exhaust is more of a personal choice since the gains are little to none by putting one on.
Get the B&M short thorow shifter...easyest to install...you can get 'em from www.summitracing.com part number BMM45087, they're cheap too! AND great quality!! 139.95!! can't beat that!! As for exaust, you should go pick up a Sport Compact Car for november, there is a good article in there about how to make a custom exaust cheap...later..
