Street Header Kit

(50 State Legal C.A.R.B. EO: D-462-1)

Whether your truck is bone stock or built for extra performance, the LC Engineering Street Header is the "best bang for your buck" bolt-on part you can buy. You should expect to see a 10-15% power increase with a good boost to the top-end of the powerband where these trucks struggle. With so many choices for a header on the market, some certainly being cheaper, we can understand if you are struggling with the decision of which one to buy. We can tell you there is a good reason why our header is still the #1 on the market and worth the extra cost.

Our most popular product is the street header kits. LC Engineering uses all 304 1 1/2" Stainless steel tubing, a huge 1/2" thick steel header to head flange and 3/8" thick steel 2-1/4" flange at the collector that accepts the stock Toyota round exhaust gasket. As if that were not enough, the whole package is coated in a high temp ceramic coating. To make the install easy on you LC Engineering supplies you with all the gaskets needed to bolt your header on your vehicle. Our header flanges are cut to allow the use of OEM exhaust manifold gaskets. These gaskets feature a metal crush fire ring and a heat deflector for the plug wires. No cheap paper gaskets to blow out with an LC Engineering Header.

Here are a few reasons why:

• LC Engineering has been designing, testing, producing and installing these headers for more than 20 years.
• Since we focus on Toyota performance parts we spend the extra time to make these headers the best they can be.
• Our header is made with high-quality materials.
• Our header is coated in a high-temperature ceramic coating.
• Our head side flange is designed to retain use of the OEM exhaust manifold gasket, the gasket features a metal crush fire ring and a heat deflector for the spark plug wires.
• We supply all the gaskets you need to complete the install.

Kit Includes:

• 4WD (81-95) Street Header
• 4WD Connector Pipe
• Street Header Gasket Set (85-95 Specific)

All Toyota Pickups and 4Runners manufactured before 1988 should be a factory non-heated single wire oxygen sensor. When installing our Street Header Kit you will notice that the oxygen sensor provision has been moved downstream from its factory location. We recommend that anyone with a pre 1988 application utilize our universal 4 wire heated O2 sensor Part # 1065034 in replace of there factory single wire. This will not only improve the signal but the gas mileage as well as the performance of the vehicle. Vehicles made from 1988-1995 should have a factory heated O2 sensor and should not need to change it unless their factory one is damaged.

NOTE: This header kit is a direct fit for 1981-1984 4-Wheel drive trucks, and includes an adjustable connector pipe to connect to the factory catalytic converter. If you have to pass emissions where you are located, or if you want to hook your air injection back up to this header you will need to purchase our air injection adapter kit, see Part # 1040000. You will also need the Heat Riser, see Part # 1045020. If you do not wish to run the air injection you will need to get the air injection block off plate kit, see Part # 1045014. LC Engineering does NOT recommend wrapping our headers with any sort of exhaust wrap. Doing so will increase the likelihood of a premature failure of the header, as it holds contaminants to the exhaust tubing and increases the chances of corrosion. Exhaust wraps will void any and all warranty claims.

NOTE: Due to many fitment differences, we cannot quote fitment to any RV. These were a custom vehicle and not a standard dealership vehicle. We do have a Test Fit Header that we can ship to you with a return label for $75. This will be the only way to confirm fitment to anything considered an RV.

Installation Note:

Over 20+ years of producing these headers LC Engineering has made all attempts to make these header kits fit as best as possible. Unfortunately there are a very small amount of applications that may require more extensive modification or even fabrication to make the connector pipe fit correctly. This is mostly contributed to numerous changes in Toyota's production along with aftermarket modifications. LC Engineering offers full technical support to make your fitment as easy as possible but they will not be responsible for any "custom" connector pipes.
