Kooks HEMI 2-inch Street/Strip Header and Connection Kit | 3103H6SS

A serious HEMI upgrade with two front-pipe setups

Build a more complete exhaust upgrade for your HEMI with 2" Kooks headers, H.O. GREEN catted connections and a separate set of Competition Only front pipes. The Street/Strip package gives you both pipe arrangements in one purchase, with the uncatted set reserved for track-only use.

SKU: 3103H6SS

More than a header-and-cat kit

The 304 stainless steel headers have 2" mandrel-bent primaries, 3" collectors and 3/8" laser-cut flanges. The H.O. GREEN cats use 4-1/2" bodies and a 300-cell substrate. Gaskets, O2 extensions, clamps and the bolt kit are included, along with the separate Competition Only connections.

Choose for your HEMI application

This package covers the supported 6.1/6.4 HEMI cars and 6.2 Hellcat applications shown below. Choose against your exact vehicle, trim and installed engine when planning the full header and connection upgrade.

Tuning for your exhaust upgrade
