Exhausts UK

[LL]

Hi all,

Starting to sort out the various ills on my "new" Sprint. It's a big valve running webers. The back box appears to be off a Triumph and my mechanic isn't impressed he calls it a "peashooter".

What's the best place to source a replacement in the UK?

Cheers,
Neil

Paul Matty does a stainless steel rear box....not cheap but when I priced a custom made one it made sense.

Try Paul Matty's or Sue Miller, both have normal and stainless steel exhaust's. I will be picking up an SS centre pipe on sunday (Stoneleigh) from the former. Both should have any fittings you need as well.

Concur with the above. I collected mine from Paul Matty who carries them in stock. Not the cheapest, but at my rate of usage, may yet last forever!

Is it common in the UK to seek to impress your mechanic?

[Elanintheforest]

Hey, if you were told you only had a peashooter you do something about it wouldn't you?

[marcfuller]

Yes - Choose another mechanic

I remember that when getting a replacement for my Sprint I had a choice of a single tailpipe version or a twin. The single was the original type fitting where as the twin pipe was two smaller boxes side by side each packed with fibreglass. The fibreglass all eventually blew out with no easy way of replacing it. But , the point of this long story is let you know how bl**dy noisy it was! I mean when new. Way past being a bit sporty and getting towards being annoying. The original single pipe had baffles inside rather than glass which seemed to be a lot better.
I've since figured out how to replace the glass if anyone is interested.

How
And can you replace the glass with stainless wire wool?

Hi

I had one made at RSR exhausts - great sound, looks good, stainless and they make in front of you, choose what you want off their shelves.

PS - Sue Miller has SS mainifolds at ?111 - good

I have one on all my elans although the only one Ive paid for was for the m100so its a slightly different kettle of fish...however for that I used jp stainless in macclesfield, cheshire......and had a 'sports' custom made one fitted at about 60% of the price of anyone else...and I tried everywhere from lands end to john o groats......
the one on my +2 may need replacing soon due to the speed humps near me wearing it down....even when I go over it at 0.5mph it still scrapes....(bloody council!!!) and I cant get the exhaust any higher....
my other +2 which is a later one however seems fine....go figure!!!
cheers

John,
To replace the glass I slit the boxes down their length, underneath, with a 2 inch cut crossways top and bottom of each cut. You can get really thin cutting disks for angle grinders that are about 1.5mm thick and go through a stainless silencer box like a knife through butter. This enabled the boxes to be opened up a bit like opening a book. Then remove whats left of the glass,(which probably won't be much).
The local exhaust "specialists" recommended some replacement glass which turned out to be ordinary old glass mat. I rolled it up anyway, stuck it in, and got it TIG welded up. Way too noisy as the mat didn't seem to absorb any noise at all.
By now I'd invested too much money in this money saving venture to back out so I slit it open again. Right down the middle of $50 worth of welding. This time I used some insulation type fibreglass that I borrowed from the ceiling of my house. Packed it in much looser and closed the hole with an aluminium plate , manifold/exhaust sealant, and some pop rivets of the sealed variety,( like are used on aluminium dinghies).
This is working way better and now any time in the future all I have to do is drill out some rivets to replace the glass. Will cost about $5 or $10 and as the silencer is stainless I'm expecting it to last forever.
It all looks quite tidy and is largely out of sight anyway.

If you want a large bore exhaust system you need to go to TTR or one of the many custom fabricators. Any standard replacement from the usual suspects will still be of peashooter dimentions. A big bore system is may be another 5bhp and a fatter torque curve.

I bought a Double S stainless maniforld from the Classic Car Show at the NEC a couple of years ago. I was not overly impressed with the quality although they did replace the unit for me with one a bit better.

I used to have plenty of noise problems when racng Elans. Remember the purpouse of the glass wool or wire wool is to vibrate and convert noise energy into heat. Thus the glass breaks up quickly. I used the insulation used in power generation gas turbines for years and it worked very well. As an alternative Rockwool, which is spun rock wool works well but does break up. However break up of fibres is much better than glass insulation. There is a formula for density of packing for different fequencies - don't ask because I no longer have it! However in the bsence of a formula don't pack too tight would be my advice.
Best of silent luck
