F1 exhaust ideas

Looking for ideas for a exhaust for the f1 I had the down pipes for the front from the f2 but I had to cut them to get them off as I was trying to save the heads wich are rather rough but might clean I’ll need to get the exhaust off today well what’s left off it

Just curious as to why you had to “cut” the pipes whilst trying to save the heads…??

Cause the mounts are completely seized on I’m gonna have to find a way to get them off

Just the nuts stuck on the studs…?? They’re a strange size stud too, 7mm x 1mm if I remember correctly.
