Heh. Same as my plans before I attack the valve train... except that I love the stock tips on the SSEi so I'll be sticking with those. Keep us posted on how it goes?

Hey Andrew,
If you want to make a run up to Alexandria next Saturday I'll set up an appointment for both of us.
I was scheduled to have it done tomorrow morning (along with a 3" resonator and 3" piping to the muffler -I still have my Flowmaster 80 Series but not sure I want to use it with 3" piping -too loud) but my schedule changed and I had to cancel.

Call me if you're interested.
BTW -I had them do the 3" DP on my 98 SSE ($45 installed), but at that time they could only use the stock flex-pipe off my original DP. Now they have a 3" mesh flex-pipe (bring header wrap to reduce the crackling sound emitted from these things), but I'm not sure how much they charge for those.
