H Robert,
My first Healey was a '64 MkIII and they have the worst of both worlds when
it comes to exhaust systems. The car doesn't have the raised rear suspension
and it uses the mufflers and 2 resonators of the BJ8 as described here
http://www.netbug.net/blogmichael/?p=382
After struggling with the original system for a short while I ended up
wearing through the rear resonators. I tried an Ansa side exit system for a
time but found that on a long trip the noise gave me really bad headaches
which resulted in my being reluctant to use the car very much.
Eventually I reinstalled the original front mufflers and cut the rear pipes
just before the bend at the back and installed a couple of pieces of exhaust
pipe, each with a bend to raise the tips as much as possible, which exited
in the same position at the BJ7 system. As I recall the rear pipes were 1
3/4" diameter.
No more headaches, a little noisier, still had the great sound.

Hi BJ8'ers
We all know that the rear cross boxes on the BJ8 catches the ground exiting
gas stations, especially when the rear end is lowered as mine is.
Three questions are:
1. If the rear cross boxes are removed and replaced with straight pipes
emerging on the drivers side, is there a big increase in exhaust noise?
Anyone running in this configuration? Too noisy?
2. Are the front boxes and hangers of the BJ7 the same as the BJ8? ie can
the BJ8 system be replaced with the BJ7 thus eliminating the rear cross
boxes?
3. Who makes decent BJ8 steel branch manifold other than the expensive
racing
folks??
