MGB & GT Forum

1973 BGT. Picture from rear is how it appeared when I brought it home. That muffler looked waaaay to low. It was obvious to me all I had to do was loosen the appropriate clamps and spin the muffler. This proved very easy as the car is very clean underneath and I spun it 180 degrees. This tucked the muffler up and almost out of sight. What bothers me now is the massive over engineered rear hanger shown in the other two pix. Is this the correct hanger for the car? I have seen alternatives in the usual catalogs that appear like a better solution but are not specific to my model year. I showed the hanger photos to a tech I know in NC and surmises it's either a hanger for a rubber bumper model or the previous owner did not install this one in the uppermost location. Any insights?

I think you may be correct and that's an RB hanger.

It looks like the one on my 78 rubber bumper. It was a pia

Michael, it looks like you could just cut the extension off the rubber bumper muffler hanger bracket, and drill 2 holes and make what you already have work for you.

I just made a rear hanger with a short rubber strap and a surplus muffler clamp. (see photo). Simple, secure and cheap. Doesn't look bad to my eyes anyway.

ps... the shiny exhaust tip isn't there for the bling. It's to prevent my calf or shin from getting burned by the hot exhaust pipe. My leg often contacted that pipe when retrieving something from the trunk after a fast run on the highway. Before I put that tip on there I spent every summer with a nice crescent-shaped burn mark on my leg.

Thanks all for confirming what I have but there still is a bit of confusion in my little mind. William, what are you referring to as the extension, is it the component #65 similar to what Barrie pointed out ?

Hangs from a universal rubber strap and bracket. Std muffler clamp.
Pipe goes over axle and turbo muffler is tucked up above floor level.

I do know that I wasn’t happy with how that hanger worked on my 78. It still seemed to hang too low. I don’t recall exactly what I did, but I know I used the upper parts of the hanger and jury rigged something to support the exhaust to the hanger to get it higher. If I feel energetic I may try to get a picture.

The cut out area in the body is for clearance so ideally the pipe exiting the muffler should be much higher.

Here are a couple of pics of the Bell SS rear exhaust mount on my ‘71 GT. Hopefully that will help you.

The comparison photos of chrome vs rubber shows the visual differences of #65. As previously written just cut the bend then use a piece of cardboard to trace the hole layout from cut piece and transfer to hanger.

I suppose that's true - - ideally. But on mine (post #6) the exhaust pipe forward of the muffler passes under the rear axle in the stock manner. If the muffler were mounted any higher the pipe would contact the rear axle when the left side is lifted on the jack or when cornering at speed around a sharp left hand bend. When I installed the exhaust I just left the muffler where it is because it's pretty unnoticeable when going down the road and raising it up that inch or two so would have been a lot of trouble and not worth it to me.

It would be very unusual for the exhaust to go over the rear axle on an MGB. Getting the pipe nested up as it is in John's photo requires either a few appropriate bends in the system and/or a rear muffler with offset inlets and outlets. If what you have works for you then that's fine but, as you said, just not ideal.
