Customer Question

I have a 2015 CVO SG, I recently had the 117 kit done with the HD race tuner. I have V&H high output true duals. I have since been told the bike will NEVER run well with true duals because of the cam action. I was told I'll have to go to a 2 into 1 system..... thoughts?

- the true duals are LESS efficient than the original stock HD head pipes.

- V&H pipes are designed by a couple of guys who spent their lives racing Suzuki's. they look great and they make a lot of noise.

there are 3 choices with exhaust pipes:

- you can choose performance.

- you can choose looks.

- you can choose sound.

I always tell people to decide which one of those three is most important to you.

if performance is most important, you will end up with a 2-into1 pipe. the best 2 are D&D and Thunderheader.

White Bros. and Suppertrapp are next....but you will spend a LOT on money on a dyno getting these pipes to perform better than a bolt on D&D or Thunderheader.

now, back to your question.....what do you mean by "never run well"???
