The headers were installed by a local shop around 1984. Not sure what brand they are. The primary tubes are 2" going into 3" collectors. These headers were had 100,000 miles on them & only had to replace 1 gasket on the engine block in all that time. The muffler shop added the pipe on the front of the header for the thermo aircleaner, & the air injection fittings.
As for fit, I was able to get the passenger side off pretty easy from underneth the truck. Only had to remove the starter & dipstick tube,& plugs. Haven't got the drivers side off yet, but looks like once the oil filter is off, it will come out from the bottom also.
You can see where the bracket was ground down for clearance in my pic.
As for sound, we had 2 1/2" exhaust, a ballance tube,turbo muffers, & exited in front of the rear tires. Had a nice rumble to it, but not real loud. Also, no fumes when the rear window was down with the exhaust exiting where we had it.
Never noticed any heat problems under the hood or in the interior.
Let me know if you have any other questions. Brad
Maybe someone can tell from the pic what brand they are.
