What performance mods?

[Andy G]

I have got an 01 ST, just purchased used a few months ago, and am getting ready to do some light modding. The cats are bad, so I am going to replace the y-pipe and the main cat with Random technology replacements, and I have some questions for you other modders:



Are the Random Technology parts the way to go? Any other brand I should check out?



Underdrive Pulleys? Available for ST? I can't seem to find any.....



Computer mod, Xcal2 the best option?



Mass air sensor and throttle body, should I upgrade? If so, where to buy?



Along with these mods in consideration, I am going to add the K&N FIPK, and move to an electric fan. I would be interested in a heavy duty radiatior as well, where to buy?



cheers,

First mods: Cold Air Intake, Exhaust. Then get an Xcal2 from member/sponsor Wayne Foy (WFOY). See the sponsors section of this site. Wayne can also give you a deal on the Random Tech stuff.

There was a post here sometime in the past month or two about underdrive pulleys, too... search for it and it should come up.



*edit* Found it. There's an "update" thread, too, but mostly it's just confirmation that this'll work.

Xcal2 the best option?

Yes well worth it

Andy, XCal2 is the single best thing you can do for your trac.

I agree with boron_iv about the XCal2, just have to tell Wayne Foy what other mods you are considering so that they will be already programmed in. Also, consider a Flex-a-lite electric cooling fan, which will help free up some more hp.
