if you can afford it, a cam change makes a real nice improvement for street driving. the SC grind works well. webcam hard welds and regrinds the SC profile on your cams for around $600. plus approx 12 hours labor (in a well equipped shop with the engine out) to swap them. improves low end a lot for city driving.
a monty muffler to replace the cat/muffler unit also is nice. minimal, if any power increase, but without the cat, the temps go down considerably, and it sounds better.
