The initial install was accomplished with only a small nibble taken out of one hanger plate to sit flush, a few polite words while placing the rubber on the hangers and fitting the muffler and it was done. However, I noticed the following:

1. The rear axle is resting slightly on the exhaust. (the axle has 1" lowering blocks). I will re-weld the hanger plate hooks down a 1/2" to get the clearance.
2. The exhaust is blocking the attachment of the existing rod type hand brake cable. I started to install an earlier handbrake cable but am missing the "compensator". The mechanism that attaches to the differential.

Can anyone tell/show me exactly where the compensator attaches to the differential. Does anyone know If this version of the hand brake cable system will give me more clearance or do I keep lowering the exhaust until I have the clearance to use either the original rod brake cable or earlier cable. I would love to hear from anyone who has successfully put this exhaust system on a rubber bumper B and what you did.

cheers

When I installed the TT system on my lowered 80B, I couldn't use the hangers that came with it or I would have had the same issue you did. I bought several generic hangers from a local parts store and modified them to work

After I got the system hung properly, it rubbed the bottom of the car underneath the seat area and also on the tube shock mount. I wedged 2X4 blocks between the piping and the rub points, started the car and let it get to operating temp and then shut it off and let it cool off. When I removed the blocks, the system stayed away from the rub points.

The other issue you have to be aware of is the tailpipe where it goes under the rubber bumper. If it's too close, it will burn the bumper.

Bob and Roger,
Thanks for tail pipe advice, I'm going to try a tail pipe extension to release the fumes beyond the bumper first.

Bob, is your B lowered or stock? Am I right to assume that you just lowered the exhaust system until the hand brake cable cleared?

My car is lowered and yes, that's what I did.

Here is a pic

Micheal,
Thanks for the photo. Did you make the bracket holding the compensator? I don't seem to find that part in the Moss catalog.

Got your PM. Stock bracket. Came with my car. How could your hand brake work without that pivot bracket? Page 213 of the green Bentley manual shows it as #29, Compensating lever bracket.

Handbrake doesn't work, that is what I am trying to remedy. The car is a 79, so it has the solid rod running between the brake drums. The rod is impossible to fit without lowering the TT exhaust at least a couple of inches. Additionally, the rod is held 3" to 4" out from the axle making the problem worse. I was hoping that the earlier cable version would permit clearance since it is anchored to the differential or at least mitigate the problem to minimize the lowering of the exhaust or raising the axle.

Unfortunately, the new 2" lowered leaf springs from moss did not lower the car (raise the axle) any more than the original springs. So, I put the 1" lowering blocks back on. The car still sits at 15.5" ride height. So, once I have an idea how the bracket/cable fit, I will know how much to raise the axle. I do not want to adjust the exhaust as it fits, hangs and sounds great.

Wow! Car has lowered springs plus lowering blocks and it still sits at 15.5", center of hub to bottom of chrome strip? If so, there's definitely something wrong, but I would have to inspect the car before I could offer an opinion why it's still sits so high.

There absolutely is no change in ride height with the 2" lowered springs. Since, the springs did not have the reverse eyes, I'm guessing I did not receive the lowered springs. The original plan was to lower the car to around 14.5" and delete the 1" lowering blocks by using the 2" lowered springs. I will probably remove a leaf and restack as suggested by Dave Headley to soften and lower about 1" plus the lowering block should give me the 14.5" ride height I want and clearance for the brake cable.

If you lower it to 14.5" and "soften" the springs, you may run into the car bottoming out on the rear bump stop. If so, cut about 1/2" off of the rubber on the bump stop.

Good advice. It was on my list.
Thanks,
