QUESTIONS RIDERS ASK
How is the Lane Splitter different from the Big Bore? Per SP Concepts' own FAQ, both run the same stepped headers. The Lane Splitter keeps a 2¼-inch baffle all the way through a 4-inch muffler — a similar deep tone with a bit more rasp, and the louder of the two. The Big Bore's 4.5-inch muffler and stepped baffle make more power, especially on larger builds.
Do the headers work with stock or autotune O2 sensors? Yes — the headers carry 18mm O2 bungs with 12mm adapters, so stock or autotune sensors both work.
Can you ship this to California? No. This is a race-use-only part that does not conform to CARB standards, so we do not ship it to California — see the California Notice above. It is available to the other 49 states.
