Angus will tell you there's a lesson there somewhere!

If it needs repair rather than replacement then I can recommend A44 Exhausts just outside Worcester, if you can make it there.

Dump the centre box and just put a link pipe on, din't have one with the Lotus engine and ant got one with the V8 ( which is quieter than the Lotus engine.... figure that one out ). I used two stubs cut off the old box and a length of flexi and made a couple of brackets, cheap as........ me.

I have a centre section with silencer deleted sat in my garage at the moment.
It is an SJ part in 'stainless' steel.
Andy.

Waiting for Andy's bits to turn up. I have removed the old box and found it was just the flange had detached. I have had it welded so can go back on if I want. Will try the straight through pipe as I can .

Edit - why make a stainless steel box and fix mild steel end pipes. Sounds like industrial sabotage

I've had shoddy exhausts like that in the past - don't know how they get away with it!

Straight through pipe on. Now blowing from 2 - 1 joint. will look at that tomorrow. Oil changed new filter.

Well. Having removed the centre box for a through pipe, either I have a new car or I have learnt how to drive it!

Remarkable difference in engine response and ease at which the car was picking up today. Flying was not the word. Maybe just the loss of 5kg pipe baggage ?

Sounds good as a performance mod.

How does it sound from the cabin?

Perhaps there was a partial blocking of exhaust gases by the old silencer afftecting engine breathing Stu?

Good question - difficult to answer. I'm considerably mutt and jeff. I said I'm mutt and jeff So I hear things differently. However, what I hear makes me smile. It sounds like a proper engine now when I push the power, but smooth when poot-ling along. Not too much of a warble but a nice tone. Time will tell if it becomes an annoying drone.

Listening from underneath I hear the tone change as it hits the y-branch and tumbles as it splits. Does that make sense?

I checked over the centre box and no blockage there. Just space for the gases to expand into.

Im not quite as DEAF as Stu, when you are pootling about the loss of the centre box didnt make much difference to the sound but it sounded better at higher revs and it didnt drone on the motorway ( Im good at that tho ). Most of my exhaust is original, sort of, its been up and down like a brides nighty over the years to reweld the mild steel flanges to the stainless pipes, cheap as .... me... again.

Has that helped with the low-speed stumble, or had you sorted that already?

That's tempting fate. It was always an intermittent item. Currently waiting for sometime special to reoccur - LITP?

Forgot to say whilst fettling the door hinge I found out my car was built by Sid Well, the RH door anyway.
