Exhaust headers
 

What does everyone think of these for a '94 Discovery 1?

Yeah, why not?

I really couldnt find the headers you were talking about but Hedman sells a set #39800 for rover thru Summit racing (176.00+11 dollars handling). I talked to Mark over at www.aluminumV8.com the other morning and he stated thats the best deal out there for rovers ( He sells the same set for over 200). They are what looks like a full length header so exhaust mods are necessary for fitment but thats the way it goes..
