What are the benefits of using a 2-into-1 merge collector?
A merge collector streamlines the transition where two pipes join into one, reducing turbulence and maintaining high exhaust gas velocity. This improves scavenging, which helps "pull" exhaust out of the cylinders, ultimately increasing horsepower and torque compared to a standard T-junction.
What material are these collectors made from?
Most of our 2-into-1 collectors are manufactured from high-grade mild steel. This material is preferred by many fabricators for its ease of welding and durability under extreme heat when used in header construction.
Do you ship these collectors Australia-wide?
Yes! Exhaust Shop Australia offers fast, insured shipping to all states and territories. Whether you are in a metro area like Melbourne or a regional town, we ensure your fabrication parts arrive safely and promptly.
How do I choose the right size for my custom exhaust?
You should match the "Inlet" (In) size to the diameter of your primary header pipes and the "Outlet" (Out) size to your main exhaust system diameter. For example, if you have 2" primaries going into a 2.5" system, you would select a "2" In / 2.5" Out" collector.
