There is some debate on whether or not aftermarket headers are illegal. Some say that they are not, as long as they are installed correctly and do not violate any emission laws. Others argue that any modification to the exhaust system is illegal, regardless of emission laws. Ultimately, it is up to the interpretation of the law and the decision of the court.
Exhaust manifolds are better than headers in many cases because they provide a better seal against exhaust leaks, they're less likely to crack, and they're less expensive.
Header wraps are definitely worth it! Not only do they dress up your engine bay, but they also protect your headers from the elements. Header wraps keep your headers cooler, which means they last longer and perform better.

I've used a LOT of LS headers for my trades, and almost all of them share the following issues:1. They inserted the collector into the bell housing or through the rear of the block.2. The spark plugs and wires are directly obstructed by the pipes.3. A deformed header flange is present.These headers actually work well with the 6.0L and 4l80e. Although I'm not sure why they chose turbo flanges over standard flat or donuts, they do the job. I was unable to utilize them due to space limitations, but I ultimately had to remove the entire collector, so I used the flanges again at the muffler input.The tubes don't interfere with the plugs or wires (it's a little tight on #3 and #5, but it's manageable), and the welds and flanges are good. Nearly parallel to the heads, the collector emerges with a downward angle of roughly 40 degrees.I'll be use these going forward.

Two pre-catalytic converters and a primary catalytic converter are installed in my car. I took it to Midas to get an estimate on how much it would cost to replace all three, and they gave me a rate of $2700! It turns out that the primary rear converter may be changed for a reasonable price or completely stripped along with the two Pre-Cats. (Off-road use only, naturally) The downstream O2 sensors will need to be removed from the direct exhaust stream if you choose to do this. You can do this by using spark plug anti-foulers or by using this device, which actually has a mini catalytic converter to process the exhaust just before it reaches the downstream sensor and tell your engine's computer everything is fine. I initially tried anti-foulers, and they were effective for a time, but finally I experienced a "Bank 2 System Too Lean" issue, which this product totally resolved! Purchase this item once and put an end to it due to the labor-intensive nature of it.

They look fantastic for the price I paid even though I haven't worn them yet. They befit a show vehicle.Update. Added them to a 1981 Jeep CJ7 that was powered by a 1974 Chevy 350. For clearance, I had to grind down one of the motor mounts. The front driveshaft is directly overtopped by the passenger-side header. To gain clearance, the muffler company had to use some inventive pipe bending. To clean your temperature sender, you might need to polish the header where it bolts to the head. The temp sender was recently relocated to the intake manifold. Consider purchasing the shorter spark plugs. The boots approach the headers very closely. Outstanding headers. very well-polished beautiful welds. thick flange fastened to the head with a bolt.

If you want to replace the exhaust manifold on your D series motor, this header is fantastic. If you have both electric fans on the radiator's front, just be prepared to put in some labor. Simple, but time-consuming. To fit the O2 sensor where it wouldn't hit or rub, a little section of the fan shroud had to be cut out. The studs between the header and down pipe were also a little difficult to install, but we managed. Additionally, I placed red loc tite on the threads of the second o2 sensor bung in case you don't need it to keep it from coming out.Expect a little work to get it in there, but overall, it's a terrific product for the price. It was worthwhile.

My 1988 Chevrolet C1500 had these heads fitted. installation of these took longer than removing the previous ones. The quality for the price astounded me. Because the flanges are so thick, warping should be avoided. I just chopped off one of the mounting tabs for the power steering pump because it would not attach to these heads. made absolutely no difference. Additionally, the oil dip stick tube won't fasten. constructing a functional one at the moment. Well worth the money in my opinion, and over the years when installing headers on various hotrods, I've always had to make some kind of modification. I'm not really trying to increase horsepower with them, but I'm hoping to get a few more miles per gallon. Who is to say? Overall... excellent value. They're simple to install and have a nice appearance. PS: Everything you need to install is included.

Nothing about their work can be criticised. Everyone who claims they broke or didn't last long enough is likely complaining because you didn't properly prepare them. Before putting these items in your car, you must sand and paint them. Use flame-resistant paint. And you ought to probably heat-shrink them.

**EDIT 8-19-18** Utilize the 100-1107 ARP header bolt set. Although the threads are the typical 3/8-16, the heads are 5/16 hex. A 5/16" wrench is much easier to use than a 3/8" or even an allen key to get on the bolt. Purchase some quality gaskets; the ones included with this kit are worthless. also purchase the collector gaskets. I continue to give the headers a total of 4 stars.First off, a 1985 K5 Blazer/GMC Jimmy WILL FIT these heads. The collectors on either side of the bottom firewall are close together, yet they still function. The old school large 25 pound OEM starter takes up too much space, therefore you do need a later model gear reduction tiny starter. I have no knowledge of any further vehicles; I simply know they match my GMC.Second, you require spark plug wires with 90-degree booting. Get heat insulation for the plug wires as well, don't forget.Third, and the main reason I gave them a 4-star rating, the header bolts that came with them have an excessive amount of shoulder. EVERYONE went down the tubes. Because I couldn't get a standard socket on the first set of replacement bolts I bought from a nearby parts store, I had to look for allen head socket bolts that would work.Overall, the headers appear to be extremely well constructed. The flanges are nice and thick, and all of the TIG welds look good. Also thick are the metal gaskets that are included. Over the following six months, I'll monitor their durability.
Automobile engines are designed to run within a specific range of operating temperatures, and engine oil plays a vital role in maintaining these temperatures. When an engine is first started, the oil is cold and thick, and it takes a few minutes of running for the oil to warm up and reach its ideal viscosity. During this time, the engine is more vulnerable to damage because the oil has not yet reached its optimum level of lubrication. For this reason, it is important not to rev the engine too high during the first few minutes of operation. Once the engine is up to
Do Aftermarket Headers Make a Difference? The short answer is yes, aftermarket headers can make a difference in your vehicle’s performance. Headers are one of the most important engine components, as they help to direct exhaust gases away from the engine. This allows the engine to breathe more easily, which can lead to increased power and efficiency. If you’re looking to get the most out of your vehicle, aftermarket headers are a great place to start. There are many different styles and designs to choose from, so you can find a set that
There is no clear consensus on whether or not headers increase gas mileage. Some say that they can slightly improve fuel economy by helping the engine run more efficiently, while others claim that any potential gains are offset by the increased weight and drag from the larger exhaust system. Ultimately, it is up to the individual driver to decide if the benefits of headers are worth the cost and installation effort.
Headers can add a significant amount of horsepower to your vehicle. The amount of horsepower that they add depends on the size of the engine and the type of headers that you have. Generally, headers can add anywhere from 5 to 20 horsepower to your engine.
Headers are one of the most popular and least expensive ways to improve the performance of a car. They work by increasing the exhaust flow, which allows the engine to breathe better and produce more power. While there are some drawbacks to installing headers, such as increased noise and vibration, many car enthusiasts feel that the performance gains outweigh the negatives.
There's no simple answer to this question since it depends on a number of factors, including your budget and what you're looking to achieve with the upgrades. Generally speaking, however, upgrading your headers is a good place to start since it will free up some airflow and help your engine to breathe more efficiently. This can lead to gains in power, torque, and fuel economy. If you're looking for more noise, then an exhaust upgrade may be a better option for you. It's also worth considering that some exhaust systems require specific headers, so you may need to upgrade both at the same
