Exhaust in England

Post by dolomitefan »

Anyone in the UK had experience of changing an exhaust?

Mine is totally disintegrating so I need to fit a new one. Trouble is shipping and taxes are expensive from the US and I was wondering about having a stainless system made. Just interested to know if anyone over here has had experience of having such a system made up. I figure it has got to be cheaper than buying a mild steel one, shipping it etc.

Guess no one has a pattern for a Greenbrier so will probably have to remove the old one first which should be fun!

Below you will find some links and information on various Corvair exhaust system options. Most would also fit the Corvair van. Any system should be secured to the engine, and not to the adjacent vehicle body, since vibration from the engine could eventually cause some stress to an exhaust system that is tied to the body.

I have no way of knowing what you can find in England and what local exhaust system specialists can fabricate locally. Hopefully this material will help you to develop an affordable solution.


Here is some past material I had posted on this exhausting subject. More "food for thought" with regard to Corvair exhaust systems...
:think: If you want tubular headers and mufflers for use in a car and on the street, Clark's Corvair Parts sells them. They require cutting the lower engine shrouds or removal of the lower sheet metal, but will fit within the confines of the Corvair body.

Good options for the street are also covered below. A review with good comments about all three possibilities can be found at the bottom.

For a fair assessment and evaluation of the different exhaust system options for use in a Corvair, from a stock dual configuration to the trombone-style mufflers to full tubular headers, see the comments below...

I have personally used the Ultimate exhaust, both type of exhaust extractors, and stock dual, and single systems.

The Ultimate exhaust header system is loud to me even with the baffles installed. The drone at certain speeds can be annoying and can be unpleasant for extended operation. Cutting or removing the lower shrouds can cause the windshield defroster to fog the windshield due to the extra moisture let in to the manifold area (not a problem until you need the windshield defogged on a warm rainy day). For best longevity I recommend ceramic coating the system prior to installation. I would not use these again myself except on a race car. (very slight performance difference noted from stock dual exhaust with a basically stock motor).

The Exhaust Extractor systems and pretty nice all in all. The large tip one is loud. I got tired of this after a while and ultimately replaced it with the straight small tip version. I really like the note of these and they are not so loud as to be annoying. This system is not without its issues however. The pipes must be bracketed to the engine or engine sheet metal near the front ahead of the first muffler as well as at the rear on both sides or drooping will likely occur. The connection at the manifold even though it seems very strong will allow the system to rotate and droop without help. Another issue is that the welded bracket that holds the extractor pipes parallel to each other in roughly the center bottom of each extractor is prone to coming loose after a period of time. I have re-welded a number of both small tip and large tip systems for this issue. The final issue is a small one. On the small systems I have installed the pipes do not stick out from under the rear grille the same amount on both sides, one side is shorter. (it is somewhat normal that they may not be spaced right to left evenly when viewed from the rear). These also should be ceramic coated for durability. No noted performance gain compared to stock duals but sounds and looks cooler.

The replacement stock type systems from Clark's are excellent. When installed with new brackets and hardware these are the most durable exhausts I have used on a Vair. No trouble or maintenance for 30,000 miles or more over 4+ years, something I can not say about the above systems based on my use of them. The complete dual system they sell with the larger tips is my choice in these. Ceramic coating not really needed for good durability but it will keep them looking good and stave off rust longer. I think there is a slight performance gain going to a dual exhaust system from a single.

Corvair guy since 1982. I have personally restored at least 20 Vairs, many of them restored ground up. See my work or contact me at: https://www.facebook.com/tedsautorestoration

Thank you for the update. Looks like beautiful work! Please keep us posted on your progress!

I had never seen a crossover balance tube exhaust setup like that before. Is that a commercial product or your own design?

I would get one from Clarks I had some stainless steel ones made from company in greater Manchester area they did a really good job but they were just too loud at first it was ok but after a while became anoying especially on long journey's.

If you do plan on getting set from Clarks I am in process of getting list together to order I can add them to my order along with anything else and split the shipping and import charges.

That could be a plan, I do have concerns about noise. I do have a small list of things to get. Were you planning on ordering fairly soon? Alternatively we could always do it the other way around, you add to my list!

I have managed to remove the old system this evening, it may be original. Broke 2 studs in the process which is no great surprise so I'll have to deal with those by either drilling them out or getting them nice and hot and using some grips.

If you want quiet, then stay with a single muffler exhaust. On a van a dual exhausts can get annoying due to the droning.

Stainless tubing for automotive exhaust tends to be thinner so it can be cold bent, therefore louder. One option may be aluminized steel exhaust tubing. Still common in the U.S.A and is much more durable vs. plain mild steel.

BTW - The FC exhaust is different after the exhaust manifolds, although you could probably make the car system work.

You don't want to bolt to the FC body, but it is fine to bolt a hanger to the engine sheet metal.

BEFORE YOU try to remove the broken studs (if done incorrectly you'll break the ears off the manifold) try davemotoheads process. Heat the studs and manifold gently and use a candle so the wax melts into the threads. Let sit a day they try to remove. Amazingly it often works better then penetrating oils!! A few tries may be needed.

I could send some pics of my stock steel one if you wanted. Very simple and any good shop should be able to make it. Just the single muffler exiting on the offside works for me, sounds great without being annoying. Has lasted for the last 5 years and doesn't look like it will fall apart any time soon.
