Possibly re-gear it, depending on what you are looking for. But then again when you re-gear, you are usually either going for top end OR acceleration. When you gear for top end, you usually loose a little acceleration/holeshot. And when you gear for accelleration you usually loose a little top end.
What about studs? You didnt mention being studded. If you have all them horsies and spin your track, you are not really benefitting. Kind of like running a high perfornace car with racing slicks on wet pavement. Yes, you'll be producing power, but not getting it to the ground. 144 is usually a good minimum # of studs to run in the SRX.
From what I have read the stock can, pipes, and reeds should be left stock as you are not really benfitting, and in some cases suffer performance loss. Plus changing the pipes usually = re-jetting, which could run into reliability issues and burning more fuel.
Plus, swap off them factory skis with some C&A's or Simmons.
