Polaris Slingshot Header by 1320 Performance
1320 Performance Mini Ramhorn Header was designed specifically for the Polaris Slingshot to produce excellent power results from 3000RPM to redline. This Tig Welded SUS304 Stainless Steel Header adds a very nice throaty sound to the Slingshot while gaining a manufacturer claimed 9HP over stock. The stock Slingshot manifold is ugly, heavy and has huge choke points because of tiny exhaust and flange ports. The manifold collector on your stock slingshot is only 1.742" inches, the 1320 collector jumps up to a true 2.5" inches.

1320 Performance Polaris Slingshot Header Features:

  • Tig welded in and out for durability
  • Ported runner and collector for extra smooth flow and maximum HP gain
  • True 2.5" inch collector
  • Precision Laser Cut Flanges
  • OEM Fitment can be used with Stock Exhaust and/or Aftermarket Exhaust Systems
  • Dual o2 Sensor Bung on Header.
  • Extra o2 Sensor Bung can be used for wide-band or another tuning oxygen sensor. Plug included if not used.

Material 304 Stainless Steel
Does the 1320 header come with gaskets or do we have to get the gasket kit. ( Chuck Geisler, 03/27/2016 1:24 pm )
Hello Chuck, 1320 does not include gaskets with their header and indicates that the header should be used with the factory OE steel gaskets. We do however sell gaskets if for some reason the OE gaskets are in poor condition.

I BOUGHT THE Alpha Powersport Stage 1 Power Pack for the Polaris Slingshot KIT WILL 1320 SERIES HEADER BOLT UP THE THE SIDE EXIT EXHAUST THAT CAME WITH THE Alpha Powersport Stage 1 Power Pack ? ( ANTHONY S., 12/19/2015 12:57 pm )
Yes it will bolt up perfectly to the 1320 header, however.. you will not be able to use the stainless heat shield that came with the Stage 1 Power Pack with the 1320 header.

Can the OEM muffler be retained with this header? ( Steve L., 11/18/2015 10:29 am )
Hey Steve - The 1320 headers will mount up to the stock flange, so using your stock exhaust will be no problem.  Please let us know if you have any further questions.  Thank you! ( SlingMods )
What is the warranty on the 1320 series exhaust products.

Thanks, Joe

1320 header
Installed this with an Injen CAI, 2 brothers exhaust, and eliminated the catalytic converter. The power difference is unreal!! Scary fast, tires just smoke everytime you press the gas up to 4th gear.
