headers for a 3.1? i cant find any
ok i KNOW summit used to sell em because i priced em out back when i had my 90 RS but i gave that idea up wen i sold it and bought my iroc, now in addition to my iroc i also have an 87 Sport Coupe with a 2.8, but im puttin in a 3.1, while it was out i figured id buy the headers for it, but NOW i cant seem to find em on summits site, i even checked the links posted here on the v6 forums and they all go right to summits home page so am i missing something or are they not avail anymore?? o.o

Look up headers for a 2.8L... that should lead you to some links.

Headers for the 2.8L V6 will fit the 3.1L V6, too. You'll just have an excuse to get rid of your A.I.R. system.

If you're in CA they're not legal for a 3.1. Only the 2.8. But....

they have provision for the egr valve, the air pump needs to go though.
just remove the underhood sticker and they prolly wont notice. the 2.8 didnt have a smog pump and there are alot more 2.8 cars then 3.1 cars so chances are the guy doing the visual wont even think about it

Headers are illegal in California. Unless your car is smog exempt unfortunately mine isn't
oh well gives me an excuse to keep the stock manifolds & the neighbors won't hate me so bad.
