can i use headers and y pipe from 4th gen(97) on 5th gen(02)? and how about if i have a ts ecu from 4th gen(96) to 5th gen(02)? how about sway bar?

 

I can tell you for sure that the TS ecu from a 4th gen will not work on a 5.5 gen. The y-pipe and header i am unsure of, are you reffering to cattman/hotshot headers or stone racing header/y-pipe? the cattman headers should fit 95-03 maximas, but the stone racing might not, i am not sure.

 

the headers re stone racing, the y pipe z warpspeed

 

you can use header and y pipe from a 4th gen on the 5.5 gen. The only thing is you have to weld the egr stuff shut on the headers.

 

sway bar is the same for 95-03

 

i remember reading that the brackets for the sway bar are different between 4th and 5th gens. at least for the Stillen RSB
