S&S Diamondback Race Exhaust System


S&S was building Performance Baggers long before it was called that and the focus has always been on making big power! The Diamondback two into one exhaust is a perfect example of a commitment to true performance. Beginning with a stepped header for maximum flow and a merged collector specifically engineered to prevent exhaust gas reversion, this system wraps up with a 4" full stainless muffler that ends before the rear axle. Diamondback is not for your Daddy's bagger, but purpose built to make big power and sound, excellent cornering clearance and just the right look.

  • 2-1 full stainless system with shields
  • Oversize header primary tubes for optimum flow and performance
  • Just enough length to make big power on your bike
  • Four bungs for easy O2 sensor installation and air/fuel monitoring
  • Computer aided design and precision bending for improved ground clearance
  • Stainless steel construction
  • Made in the USA

If I custom fit stretched saddle bags will the diameter of exhaust muffler be too large?

Putting custom bags on my 2023 Streetgluide! For performance & increased torque & loudness db's is this exhaust a suggested upgrade? With adding a Vance & Hinds Vo2 Air cleaner! I did a similar upgrade on my old Night train & my 02 Duece with a Vance & Hines & a Bub 2-1 exhaust. It increased my performance substantially! I'm looking at adding Hard Drive stretched saddle bags. FYI tenatively"

That, as I'm sure you understand, is difficult to say without having the bike here to examine to see if there's enough clearance between the pipes and those bags. There are just far too many variables at play in order to say for sure. If the stock pipes work with those bags, then yes, you're probably in the clear - but after that, again, it's really difficult to say without looking things over at our shop. We've not been able to examine this particular setup in our shop as of yet. Now, as far as performance is concerned, we're talking Smith & Smith - and a race system that's built for maximum exhaust flow. You can expect sound, and properly tuned to match, yes - it'll be a nice upgrade from the stock pipes in terms of power. All that, minus the heat that comes from the OEM catalyst, too!
