Billet Elmer Racing Merge Collectors

The hottest and highest stressed part of your exhaust manifold will almost always be your collector. Welded and cast components can only go so far before it becomes close to impossible to make them last in tougher use or at high use cycles.
This is where our Billet Merge Collectors come in.

Our Elmer Racing stainless steel billet merge collectors withstand even the harshest racing conditions, and provide good street durability as well. These are the best choice for use cases like FIA RallyCross with extreme anti-lag, diesel tractor pulling with EGT's through the roof, and harsh "two step" and load cycles of drag racing where our collectors provide unparalleled durability while maintaining decent cost.

We have over 300 designs with all flanges from t3, t4, t6, single and dual scroll, as well as v-bands in all the popular sizes, as well as pipe sizes. Check out a sample of the collectors on our webshop by clicking the button below!
