Exhaust System

As I am finally getting to the end of a long restoration project (61 Mk1), I
am in need of a decent exhaust system. Engine will have the usual cyl. head
mods and a LCB header.
Are there any suggestions out there for a decent performance muffler with a
reasonable decible level.
I have a similar setup in our Arkley using a 1500 MGA Double S Stainless
muffler that works very well, but space is a problem on the Sprite. Thanking
you in advance
