Subscribing, to see if someone has fitted one...

I have fitted an intermediate muffler ( from an MGB I believe) on my slightly larger than standard diameter Plus 2S 130/5 exhaust system. I have a Spyder chassis and that has a cut out under the gearbox tail which the muffler fits into nicely to avoid reducing the ground clearance significantly. The rear muffler is a single straight through one a little smaller than the original It makes a nice subtle exhaust for the road cruiser that my Plus 2 is and I don't need to avoid using full throttle in the city :D .

cheers

Intermediate silencer now fitted.
The noise is reduced to a more relaxed level. Still a nice sound under acceleration.

Hi Curly.

The following photos show a Steve Jenkins aluminum block fitted with an all aluminum T9 (Quaife aluminum case and cover) tranny, with a Voights conversion kit. The chassis is a bare steel TTR 26R with the largest bore TTR exhaust manifold available and a straight through silencer system (not shown). The pipe pieces are untrimmed at this time.

Y-pipe needs to go forward a bit for increased pinch bolt clearance
dsc01351d.jpg and
Front end of intermediate pipe might be trimmed to move bend forward for best fit
dsc01352d.jpg and
Y-pipe can be driven onto header down pipes more so pinch bolt may clear bell housing flange

The number 4 manifold tube just kisses the engine flange
dsc01327d.jpg and
the number 4 exhaust pipe will require a little relief notch on the engine flange
dsc01328d.jpg and
Clearance at the frame notch is probably sufficient for operational movement
