What is the collector (side that bolts to cat) size of this header?

The collector is where all the pipes come together hence,collector. The outlet can be different sizes , 2 or 2 1/2 inch exit .called a 4 into 1 header..

The threaded part is a minimum of 2". As it is installed in my aquarium, I am unable to measure. Sorry I can't be of more help.

Yes, factory cat's will come out with the factory headers...I ran custom 3" piping to muffler and got rid of check engine light with custom tune...

Its a bolt - and is standard for many couch buns. Believe it is around 5/16 - maybe - in diameter, and is about 1 1/2 inches out of bun. Worked great on replacing my standard buns. ( Actually it is both a screw that screws into the bun and then the part that sticks out of the bun is a bolt)

I am not sure if this is a mounting measurement or the intake side. I would recommend getting one that is the same as you have.

I don't have access to the parts anymore, but a "ballpark" guess, best that I can remember would be approximately 1/2". Hope that helps.

It's been almost a year so I don't really remember. I don't think there were instructions but there aren't that many pieces and I think all the bolts are the same size. I thing every piece had it's own place to fit and not much confusion on where it fit. Sorry I can't be more help.

I believe it is 1/4-20. pretty standard. I tried to use this on my mercury outboard but it would not fit under the cowl. John

I have about 5 inches of pipe after my header collector but before the Y pipe that comes with the cutout. You could get away with a little less. The Y pipe is a total length of around 6 inches, you could just cut out a 6 inch section like its a normal exhaust pipe.

I would go to the Scat website. They have all the bolt pattern measurments.

Al, I am not home to measure this pattern, but I also mounted this pump on a Honda Generac and it bolted right up. If I remember right the holes are a little bigger than the bolt shank allowing for a bit of flexibility. 2.5 GPM

Jim, The plate measures 8-5/8" from top to bottom and 6-15/16" wide. I didn't want to take out the bolts to measure the holes but the top holes are tapered. The bottom section of the holes on top is 3/4" which tapers up to approx. 1/2". I'm using a bolt with a 9/16" head for this. I'm using a bolt with a 3/4" head on the bottom holes. I have it mounted on a wall. This is a great unit. Get the Goodyear hoses. I had a Chinese wall unit w/ hoses before this and it was junk.

Sorry, I don't know the exact answer. The best guess is from the end of the "rack" to the end of the cable. The "old" cable should be marked as to the length. The last two digits in the part number describe the length. SSC13410 would be 10 feet long.

I'm not sure what it is, but on the side where the small drill and extractor is says 3/32 - 5/32 (M 3-4) - likely recommended sizes of bolt heads to extract?? I snapped the smallest drill bit so I can't even measure it, I will see if I can post a pic of the actual inside of the case..

The drive is 3/8". The bolts removed are 5/16", 11/16", and 3/4" (8mm ~ 19mm).

The intake side is circular as mentioned..there is a template provided as well. * Cutout Dimension on the exhaust side is 11.5" x 8.5"
