Headers

For the B18/B20 we now essentially have two headers - a 4-1 race header that is made to order, and a new 4-2-1 "tri-Y" header custom made to our specifications right here in northern New York. It is similar in general concept to the header we used to import from Europe, but with several improvements and better quality control. It was designed to provide clearance for a variety of intake manifolds, alternator clearance, and upper A arm clearance on 122s & 1800s set up with less than stock camber. It is less expensive than a 4 into 1 of comparative quality, and allows more room for plumbing. The tri-Y design normally produces more torque and has a wider power band in most applications, but may yield less peak horsepower at high RPM than a properly designed 4-1 header. The 4-2-1 is recommended for most applications from street, to autocross, to rallying, and even road racing applications where a broader power band is more important than high RPM peak power.

 

Street Performance 4-2-1 headers - New and improved design made in the USA for 544s, 122s, 1800s, and 140s. Designed to increase power and torque over a wide RPM range. Will work with a variety of intakes but may not fit on cars with generators. $325 Normally stocked with silver ceramic coating & 02 sensor mount - $ 475

4 - 2 - 1 headers for 240s, 740s and 940s, imported from Sweden on special order.

Custom Built Race headers 4 - 1 - $475 - $525 depending on type and  tube size

Ceramic Coating of any of the headers, black or silver - $150

Adaptors for oxygen sensors for FI or air/fuel ratio gauges added to any header - $25

Exhaust Systems

Mandrel bent, stainless steel tube systems.

Selected performance exhaust system components are now ready for 122 sedans and 1800s in stainless steel. For most applications they consist of a muffler, resonator and mandrel bent tubing. Locations of components are essentially the same as stock. Although designed to attach to our exhaust headers they can be adapted to other headers and stock exhaust manifolds.  Some components are available in 2", 2.25", as well as 2.5".  Components are available separately so that you can use them to make custom systems with your choice of mufflers. Complete sets of stainless steel 2.5 inch mandrel bent exhaust tubes for most models without mufflers - $250. Over the axle stainless tube section as a separate piece - $175. Email for more details.
