Get more enjoyment from your HEMI truck

Upgrade your RAM's front exhaust with 1-7/8-inch Kooks long tube headers and a matching Y-pipe. Choose Competition Only, Performance or Ultra-GREEN connections for your 5.7 HEMI and intended use.

SKUs: 3520H410, 3520H420, 3520H430

Choose the catalyst for your engine

Performance cats are for naturally aspirated builds; Ultra-GREEN is the catted choice here that supports forced induction. The Competition Only kit supplies an uncatted Y-pipe for competition use. All three kits use 1-7/8" primary tubing and 3" collectors, so the catalyst selection is the main difference on this page.

Choose for your DT cab and bed

These kits are for the new-body RAM 1500 DT. The Competition Only 3520H410 joins the OEM two-bolt rear flange and fits the Crew Cab short bed with a 144.6" wheelbase. Use that cab, bed and wheelbase combination when choosing this uncatted package.

Frequently asked questions

Is this for a RAM Classic?

Choose this page for the new-body-style DT truck. A RAM Classic uses the previous body and needs its own matching exhaust parts.

Are the headers and Y-pipe supplied together?

Yes. These are header-and-connection kits, with the Y-pipe choice shown against each SKU.

Does the GREEN selection supply Ultra-GREEN cats?

Yes. SKU 3520H430 supplies an Ultra-GREEN Y-pipe with the 1-7/8" headers. That is the catalyst supplied for the GREEN selection on this page.
