Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing AR side exit pipes on 3.7 Roadster

Richard I know. I was only showing that for others.

Finally got them fitted. After a lot of head scratching came up with a pair of extension brackets for rear silencer mount, to replace the the ones shown in first post. Standard front mounts worked ok albeit a little tight to flared connection to Cats. Pretty sure the factory just fit the rear L bracket supporting middle of exhaust in front rather than behind the rear cross member that supports rear of seats, when AR side exit exhausts spec'd. Removing all the trim to gain access to the chassis would have been a pain though even if possible without damage, not to mention drilling extra holes in same for the captive double stud plates.



Hard working with 3mm stainless without machine shop facilities but eventually got there. Even then was concerned about loads on the new stainless 30mm bobbins courtesy of SiFab, but when I tightened up all the fittings the mounting firmed up fine. Took the opportunity to cut back excess thread on bottom of bobbins to increase ground clearance. Not sure how they should fit in relation to running board but settled on tail pipes pointing slightly downwards and not quite proud of bodywork. Only picture I found was of new car recently sold by dealer although image below is mine.



Then it was time to test. Fired up to a subdued roar but settling down to idle no louder than standard system. No leaks so went for short drive. Definitely a throaty sound when you put your foot down, but as soon as you revert to cruise seemingly no louder than standard. Cruising at motorway speeds no louder either which will be a real bonus. To sum up sound, discreetly rorty

Looks great Richard. I'd like to fit a side exit exhaust to my 4/4 but the factory end pieces don't seem available

Well done Richard. That is a good result

Thanks for comments. Pleased the not inconsiderable expense, only justified by reverting to man maths, has paid off. Have spent rather too much on Morton recently but again the man maths stacks up to assuage any thoughts of going the CX route

I think 19 below is the part you are referring to Rob.



Part # AER4200 as fitted to 80th anniversary models. If not available you could have one made up by a specialist. With the welded bracket mating with rear bobbins, fitting should be simple.

Richard

That looks the business.

Well done 👍

Looks good Richard, I expect a proper demo in a couple of weeks

Heard them in action today and the are the dogs dangly bits.

Heared them at close quarters today , they look very expensive and they sound deep and v8 ish !
