The Sideshots are the best performing 2-2 looking pipe out there and you dont see many of them.
The secret is the crossover built in to the pipes
I basically ran a Head to Head with a Supertrapp on my bike and they were very close on the Dyno
They are not better than the stock 2-2. The stock set up with higher flowing slip-ons has a bigger and better crossover than the sideshots and will give more backpresure at lower RPMs to give a much better torque curve (no dips). Oh and they are $300 cheaper...
Installed the Cycle Shacks and I've got to admit I am surprised! They have a deeper sound than I thought they would and are plenty loud. Also got the Mustang Vintage Solo in the mail today and am loving the ride! Now it's on to the next mod... apes, risers, and speedo relocation....
