Exhaust Manifolds vs. Headers

Many people ask us here at 1A Auto what the difference is between an exhaust manifold and a header. Well, today is your lucky day because we are going to tell you….and then you can go tell all of your friends and look all smart and whatnot. It will be our little secret but hey, that’s what we are here for.

While exhaust manifolds and headers play the same role in engines, namely channeling exhaust away from the cylinder head to the exhaust pipe and eventually out the back of the vehicle, there are important differences between them. Essentially, headers are upgrade parts designed for performance applications, while exhaust manifolds are more utilitarian. There are advantages and disadvantages to each, and which one you choose will be influenced by your needs.

Exhaust manifolds are frequently formed of cast iron in a block-like configuration. This gives them sturdiness and longevity. Because the cast iron material is thick, it holds on to heat well, which is good for emissions and keeps heat from leaking to other nearby parts. The thick walls do, however, mean there is a small space for exhaust gases to pass through, and the iron casting makes the interior rough which can slow the flow of exhaust gases. This creates back pressure which keeps the exhaust from being cleared as efficiently as possible. This reduces the efficiency and ultimately the power of the engine because exhaust must go out to allow fresh fuel and air in.

This is the problem that headers are intended to solve. Headers are aftermarket upgrade exhaust manifolds that use an individual steel tube for each cylinder. These tubes all connect to a collector pipe.  The tubes are smooth and equal in length. This ensures that the gases from each cylinder reach the collector separately, avoiding back pressure. This benefit can be lost if other exhaust components are not also upgraded. If the exhaust pipe that follows the headers is too restrictive it can introduce back pressure to the exhaust system and diminish the power advantage of headers. Another disadvantage of headers is that due to their thinner walls, they do not absorb as much sound as cast iron exhaust manifolds, making them louder (although some may see this an advantage). Some vehicles do come with stock tubular steel manifolds. Primarily these are for performance vehicles, such as sports cars. Jeep also notably uses tubular steel exhaust manifolds.

That my friends, is all there is to it when it comes to exhaust manifolds and headers. Hopefully we were able to clear things up for you!

“This Car Is In Great Shape For Russian Standards”

Lada_2

The Lada may be the most unloved vehicle on the planet. Why? Well that is because buying one brand new doesn’t guarantee a complete vehicle, or reliable starting. In fact, I have heard that most new Lada’s need to go directly to a shop to have all the bolts tightened. Of course, that is assuming that all of the bolts are at least partially installed at the Lada factory, which may or may not be the case. Assuming the Lada does run when it is new, and the owner has the bolts tightened, it usually makes it to the location of its first break-down without much effort. Sure the odometer can hit six figures, but every Lada owner knows that it is an impossible accomplishment.  Chances are better that you’ll be struck by lightning while winning the lottery.

Now, this specific Lada 2110 found on eBay is surprisingly clean because it only has 15K kilometers on it! That converts to less than 10K miles for those of us in America. Unfortunately it doesn’t have a title, so if you live in a state that requires titles and you don’t happen to “know a guy“, chances are good that the mileage will stay that way forever.  Then again, with the reputation that Lada’s have, even if you do have the ability to drive it legally, 16K kilometers may never be reached. In the eBay ad, the very passionate owner mentions that it is basically a show vehicle anyway, so you will want to trailer it and wax it regularly to keep it in tip top shape.

In passionate capital letters, here are the details pulled from the eBay listing:

One Of The Most Impressive Driving Videos On The Internet

There is no shortage of videos on the internet, especially when it comes to automotive hijinks.  This particular one is several years old now, but it still leads the pack as far as impressive driving goes.  When you combine an ultra light super 7 with a driver that knows what the heck they are doing, it is truly a sight to behold.

Got a more impressive video?  Well, I’d like to see it.

Check Out This Candy Dipped 1960 Pontiac Swagger Package.

WATCH THIS VIDEO OF IT RIGHT NOW.

This is 20 feet of 100 percent pure, swagger-coated, 1960 Pontiac. It appears to have 1959 Cadillac tail light lenses, and early 1960′s Cadillac upper tail fins.  It’s sitting on monster chrome wheels that are least 20 inches, but probably more like 22′s. Air ride suspension lives underneath with fast dump valves (likely 1/2 inch at least), and they are fully connected to a keyfob.  To complete the ultimate swagger package, this sexy American steel is dipped in a sweet candy red paint. I think this swagger package is complete, son.
