The ECCPP brand is number one on the top ten list of the best exhaust headers for Chevy 350. And it made the number one position because of its quality features.

This ECCPP brand is an exhaust manifold racing header and can fit in a small block of the 1966-1996 models of Chevy 326, 350, and 400 exhaust header manifold of the V8 engine block. The product weighs moderately to improve the engine weight and reduce the payload it significantly.

It is designed with a dimension that affords it a perfect fit for different vehicles of the Chevy 350 class. Unlike some headers, ECCPP does not get in the way of plug wires to get them burnt and is adjustable to lap the engines nicely when fitting them.

A common issue with most exhaust headers is that users may suffer gas leakages through the tiny spaces between the top cylinders and the header’s opening. But with ECCPP adjustability, any leakage can quickly be sealed off by simple adjustments and tightening.

Although the little drawback for this product is that it interferes with the engine’s stater stock, it can be solved by replacing the starter motor with a smaller one.

  • Dimensions 22 x 16 x 7 inches
  • Leakproof seals
  • Machined exterior
  • Paint coated ( black)

If you think of performance and value then you need not look further because Flowtech is a combination of it all. The mandrel-bent tubing technique was used in its formation through precise engineering. The tubes are made to form collectors with 1-5/8” inches flanges.

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

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


  • It has improved sealing rings
  • Anyone can install
  • Fits nicely with engines
  • Improves engine fuel economy


  • The product rusts too quickly

The TUPARTS is a short exhaust header made of stainless steel. It weighs a bit much and has a dimension that makes it fit just well on the top of the engine cylinders. With its stainless steel material, the header does not suffer from rust like others made of metal and could serve the over for many years without the worries of replacement sooner.

They come with mounting hardware and give a perfect seal for a more efficient exhaust. Other exhaust headers are painted with heat-resistant paints and start to wear off over a longer period. However, this is not the case for TUPARTS because it comes in the natural color of stainless and does not need to be painted.

It deals with heat more dynamically; instead of resistant paints, stainless steel has a higher heat capacity and can withstand incredible heat without compromise.

The hotter it gets, the faster it cools to keep the temperature around the engine at optimum, thereby improving the compression and expansion ratios within each cylinder.


  • Installation is straightforward
  • Made with quality material
  • Come with mounting hardware
  • They fit excellently


  • They are quite Expensive
  • Low-quality packaging

The tubes are given a higher heat retention ability by coating them with ceramic and protecting other engine components that may be compromised by excess heat. Because most exhaust headers are placed at the engine’s top part, its heat can affect the paints on a bonnet and cause them to peel away if not adequately insulated.

The A-Team Performance headers have factored in those possible heat issues in their designs and provided adequate insulation. They are given mounting hardware for firmer mouths and gaskets to prevent leakage.

The gaskets are not the ordinary kinds that aim to block gas leakages but are made of yet another highly heat-resistant material: granite. This product is purposely designed to deal brilliantly with excessive heat.

Like the first ECCPP we mentioned, this also possesses some incredible qualities. But this model is adjustable while the previous one is not.

Its perfect fit to the engine and the blocks they are installed is due to the adjustable parts that align it to surfaces. They are made from high-quality stainless steel, making them tough to withstand high heat.

When hot metal surfaces react with the atmosphere, rust develops on their surfaces, but with stainless steel, users have nothing to worry about. Stainless steel is a highly improved metal not susceptible to such a reaction with the atmosphere.

Buying Considerations for the Best Exhaust Headers for Chevy 350

exhaust headers for 350 chevy

There are varieties of brands of exhaust headers, and all of them claim to be the best for your needs. 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 does one filter the genuine products from the not-so-good ones? To answer that question, you must consider certain things before buying. You should consider the following things if you desire to have the best and nothing short of the best.

However, 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; when such is experienced, they are probably incompatible with the block. The first thing that should be on a buyer’s mind is 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 it to the brand they may purchase. This way, they would avoid the stress and wastage of 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, stainless steel has a higher heat tolerance than iron. 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, like cast iron, and others allow it. Before buying, it is best first to find out the advantages of the material type your exhaust header is made of 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 to the engine and cause pollution.

Buyers would have to look for headers with high corrosive resistance to avoid issues resulting from corrosion. While some are coated with resistance paints, others use the material’s improved qualities to contain corrosion effectively.

Stainless steel is highly resistant to corrosive activities, and others have various surface improvements to slow down corrosion. If you put your money into purchasing an exhaust header, you have to be sure it will stay longer without rusting away while using it.

04. Dimensions

Some headers are wide, and others have smaller widths. Before buying one for your engine, be sure to know the dimensions that would suit it.

That would mean checking out the engine’s specifications 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 consider the dimensions, 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 their product.

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 extra bucks to get the hardware if it is 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. A lot of stress can pass through that and damages may result. To avoid all of those, buyers should 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’s 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 power to carry them, which means increased 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, go for it.

07. Ease of installation

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

Therefore, buyers should consider the ease of installing 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 installing the headers.

08. Price

Different brands of exhaust headers may have different price tags on them. Buyers must understand that the higher the product quality, the more expensive it will 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 would advise such a person to be a bit patient and build a sizeable budget to get something they won’t regret soon. Many cheap products are of inferior quality, and buying them could be a waste of money. However, there are affordable ones.
