I'm a bit late to this thread, as always. A couple of thoughts,

1) the OE exhaust is three silencers not two.
2) the small bore for the estates may be to try an prevent the 'booming' inside the passenger compartment.

Certainly true for 2.5/2500 and later 2000, but the early 2000s only had 2 boxes, with a plain tail pipe.

I'll put my anorak away.

Cheers,

My 64 and 68 both had this layout.
The best thing about a CW semi-sport exhaust, apart from being less restrictive, is there is only one silencer in the middle. I always found it nearly impossible to position the double silencers so that they didn't foul the handbrake cable or the prop shaft, and they were always hitting the ground on uneven surfaces. A standard track with a raised grassy section in the middle was a problem.

The single centre silencer has a much better ground clearance, and the slim rear silencer sits neatly against the rising slope of the boot floor.

Hi Clifford,

I agree. I've also had the straight-through centre section with a single expansion type silencer at the back. That's quite fun (on a saloon) especially above about 50 MPH when you start to leave the noise behind!

Cheers,
Mike.
