Racecraft's 4 into 1 merge collectors are fabricated using 304 grade stainless steel. They feature a meticulous mirror finish, beautifully neat welds and durable design. Each collector features a 'merge spike' to efficiently disperse exiting exhaust gases.
Our attention to detail does not stop there. We laser etch our logo on each of our products to give the user peace of mind that they have an original quality item. Each Merge Collector comes in its own custom box with the item also bubble wrapped for extra protection.
Why use our merge collectors? The answer is simple. Anything that promotes high speed exhaust gas flow will help increase and broaden an engines torque curve. Our merge collectors ensure unrestricted exhaust flow to minimize excessive back-pressure. And of course, less back-pressure equals more opportunity for high end horsepower!
Inlets are all measured ID (Inside Diameter) enabling the tube to easily slip in.
Outlets are measured OD (Outside Diameter) enabling a butt weld or even the use of our V-Band Clamp Kits.
