Interesting. I don't know why the link doesn't work, but it doesn't for me either. You can go to ttiexhaust.com directly and find them that way. They do work with power steering (I have PS). They should work with the fast ratio arms as they would be shorter that the stock arms which would move the tie rods and cross bar even further out of the way. But I don't know for sure as the website doesn't mention fast ratio arms and I don't have them.. I've cut and pasted the info from the website below, but it's not all pretty like the website.

OPTIONAL: O2, EVAC, EGT
~ Our headers were designed to fit with the engines located to the factory specifications. If the engine is not located correctly in the chassis, the headers will not fit properly. We strongly suggest you check your engine location prior to installation.
~ Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations. However, we have done our best to accommodate both factory and aftermarket component combinations. In some cases, slight modification or repositioning may be required on your part to clear the specific situation.
APPLICATION Verify headers will fit your application combinations...
