SWEET!!!!!!!!
Yeah, you are a 140 Vega nut, though. Just like me.
Go for it.
You've got the 'slip-on', two-piece, long collector version of the Hedmann header(eh, Hedder
) which I believe is somewhat rare.
I have seen many Vega headers on ebay and I have several Vega headers myself, but only one of those.
A free-flowing exhaust is the easiest performance improvement you can make on a stock Vega.
I had a header on my 74 Vega GT back in the day and the car was blast to drive.
