Exhausts

[geeman]

I was thinking about what to do in terms of exhausts, and i would ideally like to use the manifold thats already on the 1.8 cvh and just weld some stainless bends together to go to the silencer. somthing like this:

now i really would like a stainless exhaust, but i really dont want to spend more than £50-100 on the whole exhaust system, so wondered where i could go to get some cheap/free stainless silencers. Also i would need some stainless bends so am not sure where to look for those either.

I hope im not being abit over ambitious in trying to find a very cheap stainless exhaust somewhere:o :D

i too have been thinking about the exhaust route, having looked at various options by other builders i think similar to you for creating a welded turn on the exhaust down pipe, but in mild steel as its cheaper to get & easier to weld.
tho Adrian H,s solution looks good too, he,s used a 1.6cvh exhaust manifold that exits straight out towards the side of the car .
hmmm decisions decisions :confused: :D

ok, i just had a look at adrianh's pics of the maniforld and what he has done looks pretty good, but i just thought why not just use some flexible exhaust pipe to go to the side, and then use stainless on all the bits that will be visiable fromt he outside. sounds like ti would be easier than making several bends, and shouldnt be too hard?

i too had the same idea but when discussing this with "Mark" the other day, he did bring up a good point..... would the flexible type bend to that degree?
i already have the silencer & so just need to connect the manifold to the silencer, how have others done this? any pics?

The flexi stuff is a bit of a pain to weld as it's thin guage metal,bends are available locally to you Andy in Boro, pm for number.

im glad ive got a tig that goes down to 20 amps, so welding thin stuff aint a problem, im just wondering, do you know how flexible it actually is, as in would it be easy to do a 90+degree bend in.

I could be wrong geeman the flexi pipes that i have personally seen would not be capable of bending 90degrees+ :(

It probably would be possible with a long piece of flexi but there isnt a lot of room in the engine bay on the exhaust side for that!

personally im going to buy a few bends etc and fabricate my own ;)

Westfield 1600 cvh also fit 1800 cvh, usually 1 or 2 on ebay.
check out some xr3i xr2i tubular ones as well. I shortened the 2 pipes from the manifold and used 2 bends to bring out the side. cant find any pic's

[flyerncle]

I go with Mark on this one,it is possible to get a 90 deg bend but given the diameter of the pipe the radius will be large.
And by thin metal I mean thin.
45/90 deg bends in tube are available from most exhaust suppliers just look on the Bosal website and you will get an idea of what I mean and I think this will be the easyiest answer.

Good Luck.

:o Adrian .... do you fancy selling the original cvh down pipe you made? pant pant :D :D

cheers
andy:)

JUNK????? no no no no :D

ok thanks Adrian :cool:

i started cutting up the original exhaust pipe today, and hopefully will make a downpipe tomorrow, it doesnt seem too difficult as im cutting out v sections and then bending and welding, however im now out of welding gas and tig filler rods so thats another £100 blown:eek: . my cost spreadsheet is QUICKLY going skywards.
