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.

Wow, this is awesome
Wow, this exhaust header performs well. I noticed a huge difference when I take my foot off the throttle, it does not slow down as quick. The power band even seems much smoother. I did not remove the lower studs or muffler. I removed the hose clamp on top of the muffler and top spring. I pushed it down and towards the engine while putting the new header in. It went in pretty easy. I would highly recommend this product.

SS Headers
Gave my SS a great boast in power. Works great with the new exhaust system.

Header and exhaust
We really like the performance we are getting with the install of the header and exhaust.

Nice Header
Having been a mechanic for 45 years and installed many headers on performance engines this header is the quality of a Doug Thorley header. Very well made but for the price of the header, a copper seal gasket for the plug should be included since it's only 2.79 for 2. That's my only complaint. I still give it 5 STARS. As for the removal and installation goes, the exhaust manifold comes out very easy, a turn here and twist there and out she comes. As for the bottom exhaust bolts, YOU DO NOT HAVE TO REMOVE THEM! Install your new gasket on the engine. Upon installing the header push the bottom exhaust far forward toward the engine. The header can be tight but as you bring it in to the engine, PUSH DOWN ON THE EXHAUST AS YOU ROLL BACK THE HEADER TO CLEAR THE EXHAUST BOLTS AND THE BOTTOM FLANGE OF THE HEADER AND EXHAUST. It should go right in. Tighten all the nuts to specs.
