my new year revamp will be to replace the old extractors on my mk2 pinto which have more weld than original metal, and are cracked again.
Looks like either Genie or pacemaker are the only local variants. both have models with 1 5/8 primaries, 1/3/4 secondaries and 2" out. I  looked at the Ashley AFM20 which is 1 3/4 primary, 2" secondary  and 2 1/4" out, but cant justify paying the same for delivery as the pipes.  
 
The current pipes are 1 5/8 primaries, 1/3/4 with a 2 1/4 out to align with my exhaust.
 
any opinions on pacemaker vs genie

I fitted pacemaker headers, big bore because of engine mods. Good fit and finish and engine performs well with them, smooth note with 21/4 system. Have used genie on my old v8 many years ago, worked well too. Don't know what the brand was on my old set on my pinto, but same symptoms - too much weld/ crack repairs.  Len
