i have a 99 sp 500 with a uni filter and a greenspring and now have stock exhaust.i want it to run better and i was wondering if i changed the helix would it run better?what about the air intake mods /is it worth fooling with?

 

I have a stock 98 sp500. how much more power did your sp500 have after your mod? im thinking about doing the same thing to mine.

 

Save your money on those changes. Unless you want to go the route and HO-ize your '99. Nothing else really works that amounts to much.

I might just wait and see what this SP700 rumor turns out to be.
