Kooks SRT8 / Hellcat Full 3-inch Front Connections

Keep your exhaust at 3 inches through the rear connection

If your SRT8 or Hellcat build uses a full 3" rear exhaust, these Kooks connections keep the front and rear pipe sizes matched. Choose GREEN, H.O. GREEN or uncatted Competition Only pipes for the individual SRT8 and Hellcat applications below, with 3" outlets instead of an OEM-size reduction.

SKUs: 31023100, 31023300, 31023400

For a full 3-inch rear system

All three choices have 3" front pipework and 3" rear outlets. They require matching Kooks headers and a rear exhaust with the appropriate full-size connection; the factory cat-back uses a different interface.
