Picture/Diagram[edit]

A picture of one would be nice, maybe just one on the back of a car or something. 03:58, 26 January 2007 User:69.251.69.157

Derogatory words[edit]

I deleted the reference to "rice burners" as this is a derogatory term for Japanese import cars, regardless of the functionality. Exhausts of the type implied are generally used to create a showy, flashier sound, for imports as well as domestic cars. Regardless of the parts actual use, there is no such place for this comment in an encyclopedia.

I also re-wrote the deragatory nature of the "Exhaust Tips" section, as the author was clearly trying to implicate that anybody who mounts a chrome exhaust tip on their car is attempting to "fool others into believing that the rest of the exhaust is of the same diameter and of higher quality material".

Also refered to as an axle back.[edit]

The term used here is header back (exhaust manifold) though it is commonly refered to as an axle back. I am putting this back into the article. Comments? Zoli Elo 05:27, 9 July 2006 (UTC)[reply]

No reference to pollution?[edit]

Strictly speaking, the exhaust system is simply the "system" that allows the exhaust gasses to escape. It actually has no relevance on pollution. The "engine" (or rather, the combustion process) is the main mechanism for generating pollution. Now, you can argue that the catalytic converter is a pollution prevention device however this has its own section. —Preceding unsigned comment added by 206.210.106.59 (talk) 14:15, 19 October 2007 (UTC)[reply]

Dual exhaust?[edit]

So dual exhaust redirects to here but nothing actually explains why. I'm pretty sure the article doesn't actually explain what a dual exhaust is (compared to a... single? regular? one). If it does, it's not presented in a non-mechanic friendly fashion. 68.94.91.194 (talk) 06:44, 3 July 2008 (UTC)[reply]

No reference to resonator?[edit]

At least some exhaust systems include a resonator in addition to the muffler. This should be mentioned. Thomas.Hedden (talk) 01:35, 5 June 2009 (UTC)[reply]

Why is there no reference to car exhausts specifically, period? Motorcycles and boats and what have you, but nothing strictly on cars? Not to mention why it's terribly BAD to CHROME exhausts!

Response: IS it terribly bad to chrome exhausts? So... semi-tractor and motorcycle manufacturers have it all wrong? As long as exhaust temperatures don't exceed the temperature at which chrome oxidizes, and as long as the chrome job is decent, I know of no particularly good reason to not chrome an exhaust system.

Temperatures[edit]

Please add information about typical internal and external surface temperatures in various portions of the exhaust system. Also, details about points where corrosion is most common, causes, and potential steps to minimize or repair corrosion.-96.233.30.57 (talk) 21:51, 13 May 2011 (UTC)[reply]

Tailpipe and exhaust (general)[edit]

I have a number of issues with this section, none with citations but drawn from more than thirty years working as a (U.S.) mechanic.

First, the "With trucks..." paragraph, second sentence is expressly untrue; the side of the exhaust exit has nothing to do with keeping exhaust away from the curb - it has to do only with simplicity of routing the exhaust from the engine to the rear, which is not always a simple job given that the catalytic converter (if equipped) and muffler/silencer claim space in the same area as the transmission, transfer case (if 4WD), propeller shaft (driveshaft), axle, fuel tank, etc. As often as not in passenger vehicles, the exhaust exit is on the curb (passenger) side. MORE often than not, single exhaust in pickup trucks is on the (passenger) curb side; nearly all US pickup trucks with single exhaust have been equipped with right exhaust exit.

Next, the "When a bus..." paragraph about curved or capped vertical pipes. The curved or capped tips aren't there to keep foreign objects out of the exhaust, they're there to keep RAIN out of the exhaust.

Last, the "Lake pipes..." paragraph. Some cars may come equipped with "side exhaust" from the factory, but NEVER with "Lake pipes", which have no muffler/silencer but are empty open pipes.
