Would this prochamber bolt right up to stock headers on a 98 GT, it says that its for 99-03, but isnt the 98 exactly the same. Thank you

 

if it says it fits 99-03, then it fits 99-03, not 98 and below. you could probably modify it to fit but i dont know what that would include.

 

96-04 are all the same 4v or 2v doesnt matter. Only differnece is the 96-98 have hangers on them that you dont even need anyhow.

 

Speaking from experience.

 

One thing that definately won't fit right is the driver side front 02 sensor. You'll have to dislodge the female side of the plug from its mount to get it to be long enough to plug back in. STRETCHHHHHHHH!!!!!!

It isn't just your car, it is pretty much everybodies.
