I know in the Harley world 2 into one is consider a better pipe for the v-twin because of scavenging. What do you think? I'm super happy with the Gibson on our RZR though, it sounds just about perfect to me and definitely gave it a kick in the pants...
these motors run the same as a harley. wasted spark and everything. i believe they should run better with 2 into 1 and a merge collector but the lte exhaust works really really well as a 2 into 2.
these motors are sensitive to header lengths and header diameters.
my first exhaust was mathematically perfect (i did all of the math and got the header length exactly what was called for as well as diameter) and it didnt work. it was restrictive and the rzr didnt like it..
since then i've done a couple of bigger headers and found a sweet spot and it works well but it doesnt follow my math.. so i walk away perplexed..

i'm sure gibson did a lot of design work, and it should work well, i was really surprised at what a difference 2bros made with just a slip on..
