Adding our signature merge bullet to your primary tubes improves flow by helping the exhaust gases smoothly merge from four separate pipes into the single outlet of the collector. That's how the "merge" collector got its name.
Sure you could try and make merge bullets yourself but when you consider the engineering and time it would take to recreate them, you'll find that they're cheap even at twice our price! And once you combine them with a Meg's collector, you'll find that our design sells for a fraction of the price of a traditional bend/cut/weld merge collector-and you are still getting the same level of performance!
You can choose our original individual merge bullet vanes that you weld together yourself our new one-piece cast stainless steel merge bullets.
