What to use for exhaust extensions
What do you guy's that live in the really frozen areas use to extend your exhausts out of the garage when you run your cars ? I have tried the aluminum dryer duct and it lasted about 3 minutes and then blew all to pieces. I have looked at all the local auto parts stores and most of them don't have a clue as to what to use. I will also need a good length on each side but if I can find wonething that will just connect to the exhaust pipes then I can get hose to add to the length. My exhaust pipes are 4" outer diameter.
Thanks in advance, Ron:confused: :confused: :confused: |

I've seen local garages/inspection stations use large diameter black hoses. They look like rubber, but are obviously heat resistant. I'd suggest you inquire at your local garage and they might point you to their supplier. Another suggestion would be to check a McMaster-Carr or a Grainger catalogue. Scott |
That would be a great way to heat the garage in the winter.

Scott,
I have already talked to all the local garages and the BAR people up here and they don't use anything. As for the magazines we don't have either of those available around here. I thought once I saw something in an Eastwood catalog but couldn't find anything in the new one I just received. Roscoe, Even with the doors open I can't go back into the garage for a day or so if I run the cars long enough to really warm them up. That exhaust is really terrible. On the other hand I don't have spiders in the Winter. I will keep calling and there must be someone in this podunk place that knows what to use. Thanks, Ron**) **) **) |
Ron:
McMaster-Carr and W.W. Grainger (www.grainger.com) are not magazines; they're industrial/commercial supply companies whose catalogues dwarf a copy of War and Peace. They may not sell direct to retail customers however. Another thought would be to check auto supplies in your local Business-to-Business Yellow Pages. Those hoses must be readily available since I see them in use at Sears, Pep Boys, and the local Texaco station. If you strike out, I'll wander up and ask them in the next day or two. Scott |

you might try a tractor/trailer supply or a large auto parts ask if thay have flexible exhaust in the size you need.you may have to make something up so not to scratch your pipes. Good luck Bill |
Scott,
I have already tried Sears and all the places around here that work on cars. All they seem to know is that there are such things but have no idea how to get them. They just leave their doors open and use fans when they are running cars in the garages. Bill, Thanks for the tip. I hadn't thought about a tractor/trailer place but there are two huge ones just a couple of miles from my house. Freightliner is one and I forget what the other is but I go right by them on the way to the shooting range so will stop in and talk to them. Thanks for the hlp guys. Ron |
General Resource Corporation (800-334-6421) is a manufacturer of automotive exhaust systems. They undoubtedly won't sell direct to you, but should be able to steer you to a retailer.

Call one of your local heating and air conditioning supply companies (not a dealer) and ask them for some 4" stainless flexible duct. It is corregated and can be bent. It should come in 25 foot lengths. It is also made in aluminum, but I don't know how that will hold up against heat.
|
Grainger won't sell to an individual direct, but they will let you use your personal credit card, and send it to your attention at your work address.
McMaster-Carr (www.mcmaster.com) will sell to anyone. As above, both are large industrial supply houses. Anyone in the maintenance field needs to have one (or both) of these catalogs for ready reference. And both make War and Peace look like a short story. Another source might be J C Whitney. They sell flexible exhaust tubing. Like yourselves, I open the garage door and turn on a fan, when running the engine for brief periods. |
NAPA has an "exhaust ventilation assembly", part number BK 823-1098. 3" x 11 foot long, says is "high heat-resistant rubber hose. (600 degrees fahrenheit) . $120. Kinda steep, but what can you do. Look in their tools and equipment catalog, pages 176 and 177, in the 2002-2003 catalog. Good Luck. Edley

Thanks all,
I checked with NAPA and they can order the 11 foot 3 inch hoses for me for the above stated price which would take care of one of the Cobras. But they can't come up with anything that will work on the 4" exhaust pipes. Also talked to the truck places and they have special built in units which vent out the celing and don't sell anything like that to the public. I will keep trying and I did try the flexible exhaust tubing once years ago and it didn't stand up well to the heat. Maybe for the larger exhausts just bigger fans and run that one in the garage as always. Darn rain is really getting depressing. My yards are like a swamp and it will take weeks for them to dry out even if it stops raining and the sun appears again. Happy New Year to all. Ron |
How about something from a marine engine or diesel truck? You would need something like an asbestos or fireproof extension....not that long....just enough to absorb the heat.
You could also then use a reducer and utilize the standard gas station stuff. Roscoe |
Roscoe,
I think I am going to go over to the big Freightliner truck repair center tomorrow and talk to them. They are only about 3 miles from my house and the only place I haven't called or talked to around here. Thanks for the help. Ron**) **) **) |

At most truck centers or truck stops they sell very heavy duty flex pipes for the diesels. They get really hot as they are down wind from the turbo. You probably could get away with 3 or 4 foot of that stuff then connect it to some cheaper non flex to go out the door. By the way Do you need to run both cars at once?:LOL: |
Alex,
I never run both cars at once. The stuff from NAPA is on the way and will take care of the 69 Cobra. I will just wait until it isn't raining and let the replica down off the ramps and move it out the door and run it. To many things to do and to little time or I am just to old. Ron :) :D :LOL: |
NAPA has all sorts of adapters. Look in the catalog at those pages; You should find what you need. Edley

Unlike standard cars the exhust is very hot and will melt most rubbers (except HT silicone, expensive) so most shops use a vacuum/blower to pull additional cooling air out the flexible portion of the system. Often a 4 inch steel heater duct with an adjustable 90 on the end will be used before the flexible section. The steel may have a damper on a "Y"or vent holes to let the cooling air in. (This can also be used on a dyno) The flex must be strong enough not to collaps with heat and vacuun.

Ron,
NAPA has what you need in their sales bulletin that is valid through March 31, 2003. The bulletin is called "NAPA Real Deals". Typically there is a pile of them sitting on the counter at your local NAPA store. On page 35, they list the exhaust tubing in the following diameters: 2.5" 3" 3.5" 4" 5" You indicated that you wanted the 4" hose. The part number for 11 feet is BK 827-5054. Robert |
I just got a catalog from Northern Auto Supply that has exhaust hose and collectors. The cost for 11' of 4" is $89.99. There web site is NorthernAutoSupply.com. Telephone number 1-800-468-8298. They also have a lot of other auto tools, auto lifts, etc. This is a division of Nothern Tool & Equipment Co.
Have fun, Ray |
