3.4 Headers

The headers, a vital component of the exhaust system, are meticulously crafted from robust 3/4″ stainless steel. This material choice not only ensures durability but also contributes to the overall performance of the engine.


The “Y” pipe, another crucial part of the system, is designed with precision to terminate in approximately the same location as the stock 2.8 “Y” pipe. This strategic positioning allows for the seamless integration of a catalytic converter and a proper muffler, resulting in a mellow and pleasing exhaust tone.


This design also facilitates the use of our 2 1/2″ Cat-Back exhaust system, perfectly matching the flow requirements of your high-output 3.4 TDC engine. This synergy between components ensures optimal performance and efficiency.


The “Y” pipe comes shipped with 3-bolt flanges, ready to mate with your existing exhaust manifold. Additionally, it features a 2-1/2″ 3-bolt flange designed to connect with a 2-1/2″ down pipe. These features make the installation process straightforward and hassle-free.


Constructed from 2 1/4″ 16 gauge mandrel-bent steel or stainless steel tubing, the “Y” pipe showcases strength and durability. Its design ensures a perfect fit for both the early square port and later rectangular port TDCs, offering versatility and compatibility.
