I need to know.. Thanks

 

I dont know, but i will bump for ya

 

i think the Y pipe fits both 2wd and 4wd trucks. i think it's the headers themselves that are 2wd or 4wd specific. inmotionperf.com has listed on their site 2wd headers and 4wd headers, then the y pipe says "fits both 2wd and 4wd".

wow i totally misread your post. nevermind. you asked about stock Y pipes, not pacesetter ones. sorry about that. disregard what i said.
