EXHAUST COMPONENTS 
Morgan Classics 1950-2004
WHEN THEY ARE INDICATED
CROSS REFERENCE THE COMPONENTS BELOW 
WITH THOSE INDICATED IN THE SYSTEMS 

 

 

 

 
WATCHPOINT: Morgan/Rover exhaust systems have a scary element about them. They have to use steel bolts or studs into aluminium heads. Steel and aluminum together can cause problems as the steel can have lunch on ally threads if you over tighten. As well, over tim, the two fuse and you can wake up one fine morning and find you have de-threaded your heads when you remove a bolt. Yet, they can often loosen. Loctite will not do the job because of the great heat in that area makes it a poor option. 

I use lock tabs made for the engine. It makes the manifold installation I bit more fiddly, but they allow you to use the bolts at the correct torque 14lbsft with the assurance that the bolts will still not fall off. 

I find the stock lock tabs (above) rust and look unsightly. You can have them powder coated or find them in stainless steel.

 
Exhaust Clamps
by GoMoG
I use the clamps on the right for all the reasons that should be immediately apparent. They create a better seal and support without damaging the pipes. They do not rust. They are aesthetically far more attractive. I purchased these at Jegs, the large American aftermarket supplier. 
Exhaust Locking Tabs
by Gary Kneisley
Here is a neat exhaust bolt locking tab. It is effective, forever and minimalist. Available in polished stainless from Jegs, Summit and other US auto shops. Gets rid of all that fiddling with the originals.
