Upgrade the front exhaust and keep your favourite rear system
Complete your Kooks header conversion with H.O. GREEN catted front pipes that join the factory-style rear exhaust. The 3" front pipework transitions to 2-3/4" OEM outlets, giving your SRT8 or Hellcat a matched front arrangement while retaining its rear system.
SKU: 31013400
The OEM-outlet choice
These connections are the 2-3/4" rear-outlet version. That interface is the useful distinction when choosing between an OEM-style rear system and a full 3" conversion.
Pair them with matching headers
31013400 requires Kooks headers. It covers the specific Charger, Challenger, Magnum and Chrysler 300 SRT8 applications listed below, including the 2015-2023 Charger and Challenger Hellcat ranges.
Matching products
For the 2015-2023 Charger / Challenger Hellcat 6.2, pair these OEM-outlet pipes with the Hellcat 2-inch headers.
