Bushings + Struts + Exhaust + K & N Air Filter = Whoa!

I replaced the last two pairs of old bushings, the top mounts and the front tie bar bushed.  It stiffened the steering up a little, but it still seems a little vague.  I'll need to look into that, perhaps its the steering rack or the its bushings.  I also put on the NOS Koni sport struts.  Got them adjusted they way I wanted, and wow, did the make a big difference in ride.  I got the top mounts from http://www.motomobil.com/ .  That + the new Koni's eliminated a nasty clunk from the front end,

 I took the car in and had a 2" exhaust put on including a new Catalytic Converter.  The old cat was all clogged up.  When I pulled it out of the garage, it was very lively and you could tell it was breathing much better, but still felt a little bit reserved.  When I got home I replaced the air filter with a K&N air filter, and it woke right up.  Whoa!  It was super responsive and quick.  The  new GT cam seems to like higher revs than the stock cam.  It sounds like a proper British motor now.
