1275 exhaust - two questions!

I want to replace the exhaust system on my 1275cc Minor, which is fitted with the CS Autoclassics/MM Centre rear suspension system.

This uses radius arms to locate the axle, which limit the amount of space for the up-an-over part of the exhaust, so I need to get a system custom made or adapt a proprietary one, probably the 5/8”-bore system from Maniflow.

So I have two questions:

1. Can anyone recommend a specialist not too far away from Maidenhead, Berks/High Wycombe, Bucks, able to make exhaust systems in stainless or mild steel for a reasonable price?

2. Is there anyone not too far from me (see above) who has a Minor fitted with a full Maniflow system, and would be happy for me to have a look (and a listen!) at their installation?

Thanks all!

You mean 1 5/8" - not 5/8" which would strangle the engine.
Why not go under the axle - you do not have to go over the top.
Here is the Maniflow system:-

My first performance exhaust system which was based on a Austin Healy BMC Special Tuning system went under the axle and had plenty of clearance for both up and down axle movement and ground clearance.

Thanks guys - will check out the under-axle option and also call Powerflow. And yes, 1 5/8-inch bore!

In the meantime, I'd be interested to hear from anyone with a Maniflow system on their car that I could have a look at!
