Performance Exhaust Overview:
A performance engine is an integrated affair. When you modify one set of components, you have an effect on other systems. On a mildly modified engine, a minor upgrade in either the cam specs, exhaust system, or intake can be done independently. For performance, camshafts work best when integrated with upgrades in the exhaust and intake. The exhaust system is probably the first area to improve on any engine, because this will only enhance future modifications. The study of Physics tells us that we usually can't get "something for nothing", but when adding headers and improved exhaust components to an engine, we almost do. The improved exhaust flow and velocity derived from tubular headers and free flowing mufflers is one of the only modifications you can make to an engine which will improve both power and fuel economy.

These outstanding headers are built especially for Motorsport to our strict specifications. The thick exhaust flange is flat machined to promote a consistent seal. It also prevents warping and eliminates the need for spacer height modifications. Exhaust ports have high-quality welds to ensure leak-free performance. We use 1 1/2" primary tubes to ensure increased exhaust flow without any performance loss. Can be attached directly to the stock exhaust components or our Motorsport performance exhaust systems (choose stock or 2 1/2" adapter (pipe diameter of the exhaust you are going to use)). Special installation gaskets are included (do not use original equipment type exhaust gaskets with headers). This header configuration is for original "square exhaust port" cylinder heads only. Includes ports for the EGR Valve, and the original "smog rail" to attach, which routes fresh air to the exhaust originating from the Smog Pump. If you believe you may be required by your local motor vehicle department to have a working EGR and Smog Pump on your original 1973 240Z, this would be the header for you (the EGR and smog rail ports are threaded, and could be "capped" very easily if desired).

Thermal Coating:
This header comes with a highly durable and effective Aerospace Thermal Barrier Ceramic or TBC coating, which is good up to 1300 degrees fahrenheit. The satin "polished" silver finish coats both the inside and outside of the header. This does a number of things. First, it cuts radiated heat by approximately 40%. Not only does this help to keep your under hood rubbers and plastics from drying out, it also lowers the temperature of the fuel and air which translates into increased performance. Secondly, locking much of the exhaust heat in the pipe keeps the exhaust flowing more rapidly, also increasing performance. Finally, it protects the header tube metal underneath the coating from corrosion. Please note that the adapter portion is not coated. (Note: If you are interested in creating a custom color scheme under your hood, you may also want to consider our non-coated headers, which you can paint to match however you wish. See part 15-6008 in Related Items below.)

Head Casting Number:
While not required to place your order, it is helpful for us to know your engine’s cylinder-head casting number. Some early Z-cars have had engine or cylinder-head swaps, which could have an effect in the determining the correct header for your unique application. If you know the cylinder-head casting number, simply type it in the box above. If you’re not certain, just leave that field blank, complete your order, and we’ll contact you to make certain you receive the right header the first time. Other companies may not take this extra step, but we’re serious about your satisfaction. Please be sure we have your current daytime phone number or monitored email address so that your order may be expedited without delay.

Click the image above for an example.

Exhaust Adapter:
Choose stock or 2 1/2" adapter (pipe diameter of the exhaust you are going to use). Early Z stock exhausts were about 47mm in diameter (approximately 1 7/8"). If you have your original exhaust system, or it has been replaced with matching parts, choose the stock exhaust adapter. If you are installing one of our performance exhaust systems, or creating your own system, choose the 2 1/2" Exhaust Adapter.

Smog Legality:
Even with the EGR and smog rail fittings, headers may not be street legal in some areas. Check with the motor vehicle code/department in your area.
