Default 65 side pipe

I'm installing side pipes on a 65 that did not have them originally. Do I need to remove the small tabs that are located along the side of the car below the doors, or can I just leave them?
Thanks

Originally they were cut off on a sidepipe car. It won't hurt to leave them, and if you decide to remove the sidepipes, you'll still have the tabs. There was also a radius cut out of the inner fender well shield also behind the exhaust tip. I don't know how it would look, but you could Black out the tabs so they wouldn't be as visible. Look at your trim tag and see if it was an "S" or "A" body. AO Smith bodies did not come with sidepipes. Just something to think about. Personally I love the sidepipes.

My coupe has owner-added sidepipes ('65). The front body tabs have to come off, but the rears don't interfere and don't get hot from the exhaust.

The metal rocker brackets - it's much neater to cut them off than just bend them back (which will work). But leave about 1/2" stub exposed.
Makes it easier to go back by welding new bracket sections back on.

the front tabs do not need to come off but it does look better.Here is a coupe that had pipes added with the tabs left in place.

I am not sure that this is correct. If that was the case you would be able to see the evidence of it. On my car (which is an original side pipe car) I don't see anywhere that it had the rocker moulding hangers on it and were cut off. Also, if that was the case you would never be able to tell if the car was not a side pipe unit. Any St Louis built body could be considered correct, even under NCRS guidelines.

Perhaps the factory side pies car did not have the tabs at all?

If it was my car an i was going to add sidepipes i would not cut off the tabs
If i had to bend the tabs i would bend them as little as possible

The sidepipe frame was different also, in that it had the holes for the pipe hanger brackets were punched into the frame for the pipes, but only in St. Louis. A non sidepipe car will not have the punched holes. They can't be duplicated.

You'll find all the pages from the AIM for installing side exhaust at this link. There are also some other bits of info on there too.

Actually, there was no difference in the frame - all of them had the "keyhole" at the rear of the side rail for the rear pipe hanger carriage bolt.

Also, the rocker molding support brackets on the birdcage sill weren't cut off on an original sidepipe car - they were never welded on to begin with.

If the tabs is left in place or cut off i suppose that there is no way you can see any difference except from under the car and the front on the fenders which i would never cut off to add sidepipes?

I am sure there is but for me it looks like the lower front of the fender in front of the side pipe is the only thing i can tell is wrong on the picture above

My 65 is an A.O. Smith bodied car, When I installed the side pipes they were a very easy install, I did not have to cut or remove anything. I do not have that little fender tab at the front of the pipe. I guess someone may have had the pipes on before and removed them before I bought the car
