i hear that, but most updated the y pipes to fit the 80e as well as 60e. bothersome is all.

They aren't designed to work with an 80e, why be mad at speed engineering?

Because they advertise updating the y pipe which mates to their lts to specifically accommodate a 80E. Wouldnt you assume if someone was making special revisions to a y pipe the headers would at least clear lol.

Didn't you say the HEADER primary hits the trans? You're saying they advertise a Y pipe to work but you're saying the header is hitting. So sounds like they don't advertise the header itself to work with the 80 and they probably won't make a header to clear an 80 since you just have to cut a tab off.

Sounds like they are saying there is a y pipe to clear an 80e, you're saying the headers hit, so maybe the headers work with the tab cut off the trans and the 80e y pipe is different to clear another part of the 80e that the normal 60e y pipe wouldn't clear.

I didn't know they advertised them to work with a 4L80 so yeah man if they do advertise it to fit and doesn't I'd be pissed too.

Fortunately it's a super easy fix.

If you just need a little room from the header you can try what I did. I started the truck and let it run and revved it a lot to get a bunch of heat in the headers. After getting them hot I ratchet strapped the header to the frame and made a light pull on the header until it moved over the 1/8th inch I needed it to move.

I set out straps and got a plan before getting them hot, I also quickly wrapped the collector with foil so it wouldn't burn the ratchet strap

They simply advertised the y pipe has been updated to fit the 80e, it wouldnt make any logical sense to update a y pipe that goes with those headers if the headers dont fit. thats really putting the carriage before the horse. anyone buying the y pipe is buying the headers in most cases. could have been a simple update. have since hacked my tab off lol. truck goes for a dyno tune tomorrow morning. only lot drives atm.
