Sealing rings are present to aid keep out any gas leakages that may occur. Due to the high heat that the header may be subjected to during its use, it is coated with super heat-resistant paint.

And the black color paint also gives it a stealthy look that blends with other components of the engine. In comparison to the ECCPP brand, Flowtech comes with a larger dimension which affords it compactness. The Flowtech brand of exhaust headers comes with all hardware for mounting it to engines.

Buying Considerations for the Best Exhaust Headers for Chevy 350

There are varieties of brands of exhaust headers and all of them claim to be the best for your need. However, some are not worthy of being called the best. Any brand aims to make sales and accrue revenue. And they will convince you with the most enticing words to make a purchase. But, some of them are genuine.

So, how do one filter the genuine product from the not-so-good ones? To answer that question, you will have to put certain things into consideration before buying. The following are some of the things you ought to put into consideration if you desire to have the best and nothing short of the best.

Although the best may not be the same for everyone because individuals have their preferences. Generally, the things that should be considered are;

01. Compatibility

Certain brands may not fit as they should and when such is experienced they are probably not compatible with the block. The first thing that should be on a buyer’s mind should be the compatibility with his block.

And that means they will have to know the details about their block size and the requirements. When buying the exhaust header, the buyer should relate the information collected about his block and match them to the brand they may choose to purchase. This way they would be avoiding the stress and wastage that comes with replacing one incompatible brand.

02. Type of Material

Another very important thing to consider when buying an exhaust header is the type of material used in its construction. Different material has their respective tolerance to heat. And heat is dealt with differently according to the material.

For instance, a stainless steel material has a higher heat tolerance than an Iron material and while the header made with iron suffers distortion due to expansion, the stainless steel would remain intact even after being subjected to very high heat.

Some other materials types can withstand tremendous heat too like the cast iron and some others allow it. Before buying, it is best to first find out the advantages of the material type material that your exhaust header is made, so that you can use them according to their specifications.

03. Protection against corrosion

Corrosion can comprise the integrity of the material used for the exhaust header. If the tubes of the header become compromised, it will cause gas to leak through its surface. If not controlled quickly the leakage would result in power loss on the engine and cause pollution.

Buyers would have to look out for headers that have a high corrosive resistance to avoid issues that may result from corrosion. While some are coated with resistance paints others are uses the improved qualities of the material to effectively contain corrosion.

Stainless steel is highly resistant to corrosive activities and others have various improvements on their surfaces to slow down corrosion. If you put your money into the purchase of an exhaust header then you have to be sure it would stay longer without rusting away while using it.

04. Dimensions

Some headers are wide and others have smaller widths. Before attempting to buy one for your engine, be sure to know the dimension that would be suitable for it.

That would mean checking out the specifications of the engine to know her requirements and getting a bit technical by doing practical measurements from the one you’re replacing and matching it to the new one.

If one fails to bring the dimensions into consideration, they risk getting an exhaust header that may be too wide for what is required or even too small to fit properly.

The consequences that could result from this mismatch are either the header obstructing other engine components and getting burnt or could result in gas leakage. For those reasons, buyers should always consider the dimensions of the product they buy.

05. Mounting hardware

You don’t want to buy an exhaust header and yet go in search of the hardware components to fit them to the blocks. It would cost you extra bucks to get the hardware if they are not provided in the package. And you may encounter some difficulty finding the components that would fit it appropriately.

Sometimes, you would have to adjust the header or the block by expanding bolt holes or filling them up to drip smaller ones to achieve firmer fitting. It can be a whole lot of stress passing through that and damages may result. To avoid all of those, buyers should simply look out for exhaust headers that come along with their mounting hardware.

06. Weight

The weight of the exhaust header is another important thing to consider when buying one. The cost of gas keeps inflation and you want to be economical about your vehicle fuel consumption rate. A vehicle’s consumption rate is a summation of its payloads and mileage when other external conditions are left out.

The more the payload, the greater the amount of power to carry them, and that means an increase in fuel consumption. For that reason, buyers would have to be cautious about the weight of the header. Two exhaust headers can weigh differently but serve a similar purpose. If the less weighty one has the required qualities then go for it.

07. Ease of installation

When headers are easy to install, we can just do a DIY and have fitted to get them ready for use. when they are too complex to install one would have no option but to hire an expert to get them fitted. And that would mean paying extra money.

Therefore, buyers should consider the ease to install a brand before closing a deal. They should look for the instruction guide and see if they are comprehensible and if customer service contact is available then use them to ask for help with installing the headers.

08. Price

Different brands of exhaust header may have different price tags on them. And buyers must understand that the higher the quality of a product the more expensive it is likely to be.

However, this is not a general principle as some expensive brands may not exactly meet the required OE standard. But, you still have to consider your budget before going to buy one.

Perhaps one may want a quick replacement with a limited budget. In that case, I will advise that such a person should be a bit patient and build a sizeable budget to get something they wouldn’t regret soon. many cheap products are of inferior quality and could be a waste of money buying them. However, there are affordable ones.
