High Horse Performance is Veteran Owned & Operated

These Stainless Works Hemi 6.2L and 6.4L 3" catted pipes connect the factory "shorty-style" exhaust manifolds to the existing OEM slip-fit connection point in front of the factory X-pipe making this exhaust upgrade an easy bolt-on mod. Stainless Works mid-pipe kits are built from corrosion resistant 304 stainless steel and TIG welded for strength and durability at their state-of-the-art facility in Streetsboro, Ohio. This kit even includes O2 bungs for oxygen sensor direct re-installation. 

Catalytic Converter Options:

  • Standard Cats: These high-performance catalytic converters work great when it comes to giving you better performance from a higher flowing cat while keeping your exhaust gases in check and your car emissions legal in most US states. These Metallic cats do have their limitations and cannot handle the extreme exhaust temperatures seen in highly modified forced induction vehicles. The standard cats are recommended for use on vehicles up to 600BHP.
  • GREEN Cats: Also known in our industry as GESI cats are high Platinum, high performance catalytic converters. These are 400 cell count EPA legal cats and can handle the high exhaust gas temperatures of highly modified forced induction vehicles on pump gas or ethanol fuels. These cats are rated to support over 1700BHP!

For Racers:

  • If you race competitively in sanctioned events on non-public roads where Federal EPA compliance and regulations allow for you to operate a motor vehicle under non-regulated conditions, simply Add the "Race Day Pipes" for a quick and easy racing solution to save your catalytic converters for the streets. 

Fits all 2015+ 6.2L Hellcat and 6.4L SRT Challenger and Charger vehicles.
