My rally car's back box is rotten (and it turns out to actually be a centre box i.e. 'straight through'!), so I'm considering the following:
a) Using another centre box as a silencer (to minimise back pressure) -but you need a certain amount of back pressure to help the combustion cycle, so not sure if this would be ideal
b) As above but with a big straight through silencer that my mate found in his garage. However, this may prove too noisy for scrutineering -no way to tell until we weld the right pipe onto it and fit it to the car though (although I do have a decibel meter App on my smartphone so at least we can check it before we get to an event).
c) Buying a generic sports/performance silencer for it (preferably one that is repackable for maximum life): http://www.maestro.org.uk/pp_class/s...p?product=2361
d) Using a normal road silencer from a similar power/spec car (we have an old centre box and also a silencer from an Escort XR3i knocking about that we could use). However, it isn't a 'straight-through' silencer so this won't give max power: http://www.ebay.co.uk/itm/Exhaust-Re...item2ec5e6cfcb
N.B. There is no centre box on the car at present (is it worth putting one in?). The engine is an early 80s 1600 8v in a mild state of tune producing between 100-120Bhp estimated.
e) Get a standard MG Maestro 1600 silencer (and also possibly the centre box) for £40 & £51 respectively off ebay -or even the local exhaust fitting depot

f) Get a sports/performance exhaust for the MG Maestro 1600 (if you can find any!):http://www.maestro.org.uk/forums/showthread.php?t=9212

This is for the 2.0 EFi (and is too expensive for me):

but there are a couple of useful exhaust contacts on this page (search for 'Bell Silencer Services' and also 'Exhausts'):

Any tips on which way to play this one?
