Ok i just got done installing edelbrock headers on my 305 TBI vert. I removed the AIR system and welded up the holes for it... the headers were from a friend and did not come with the y pipe. I found it on summit for a good price but it sais i need a y pipe crossover pipe. WHat is this crossover pipe they are talking about?Edelbrock Y-Pipes: EDL-25-9509 - summitracing.com theres the link look in the notes section. Also I dont have a hole for my O2 sensor. where is the best place to put a bung for it? WHat is the best high flow cat that i can get? Where is the best place to put a cutout?

Sorry for the long thread but TIA!

 

anybody got anything to say? please

 

dont think u need crossover pipe, that is for emissions that plug into the cat.

put o2 sensor closest to flange on y pipe u can get on drivers side.

get a magnaflow high flow cat, or any brand will work just fine.

put the cutout right after the cat.

 

ok thanks! i had no idea what the crossover pipe was but now i do. ill just fab my old one up if it is for the emmisions.

 

have a good day.

 

thanks traviz!
