I have a BT7 too so this may only be half relevant....
I took the pair of pipes that run from the box to exit at the rear off.
I left the box in situ.
I took a series of relevant measurements and made an accurate full scale
diagram of a pair of side exit pipes.
I took it to a local stainless steel/exhaust box man who made me up the twin
side exit pipes complete with hanging bracket.
Why?
I could swap back to original set up if/whenever I want.
Over here, at least, one has to buy the side exit box with pipes as one big
expensive unit.....my way was cheaper and I got to choose size etcetc.
Worth considering.
Yes, it does help with clearance issues which, I think, are worse on BT7s
than on later BJ8s.
Of course, I started from a different setup than you, which sounds like the
old Irish joke....."if I'd wanted to get to O'Shaugnessy's Bar, sure I would
never have started from here..."

Robert,
I had the same problem with my BT7 with the exhaust on the driver's side.
The only solution is to have the exhaust exit on the side ahead to the left
rear wheel. That worked for my Healey. The exhaust note is louder, but not
unbearable.
Good luck with your problem.
Happy Healeying,
Max
