American Racing Headers for 2006-2008 Dodge Ram 1500 5.7L, 1-3/4" X 3" DHRE34NC, Connection Pipes No Cats.
Hemi Ram fans, your 2006-2008 truck no longer has to live with extremely restrictive, power robbing exhaust manifolds. ARH has once again answered the call with a high quality 304 S/S long tube header system with a 3" Y-Pipe. The system features 3/8" thick flanges with tig welded and hand ported inlets, optimized and near equal tube length 1-3/4" primaries, merge collectors with scavenger spikes, true 2 into 1 merged y-pipe and your choice of 200 cell metallic substrate cats or off road Y-Pipe. All grade 8 hardware, gaskets, clamps and O2 Ext. harnesses are included. Best of all, it's 100% US made.
Recent testing showed 22 RWHP and 27 RWTQ before tuning. Want more? How about a great fit and easy install? We have you covered. If you want 2009 and up Hemi power for your 2006-2008 5.7, American Racing Headers has what you need. (Tuning is required for optimum results).
seriously I know you're talking about a Hemi Jeep WK....there could be all kinds of interference from stuff that sits in the engine bay of the Jeep that the designers wouldn't be accounting for, since they're made for a Ram truck.
And, if it was me, I'd build a whole new exhaust - true dual, no Y collector, 2 high-flow cats, with side pipes
The SRT8 headers will definitely fit, many people have put aftermarket SRT8 headers on their GCs over on the SRT8 forum.. This is where I got my idea, Im going to be running OBX SRT8 headers, they are cheap so if motifying needs to be done I wont feel bad hacking up $1300 headers.. You dont need new cats, HEMIs come with high flow "spun" cats from the factory but thats up to you...
Here are the two photos and verbage off the SRT8 Cherokee site:
5.7 HEMI WITH OBX HEADERS, PERFECT FIT HAD JOHAN FROM DIABLO DO A CUSTOM TUNE FOR ME. MY BEST ADVICE DO WHAT JOHAN TOLD ME TO DO PUT THE STOCK CATS ON WE PUT MINE ON AND CUT THE RESONATORS OUT PUT PIPE IN THERE PLACE. WE PUT CATS AFTER THEY MADE THE TURNS. THE SRT AND 5.7 HEMI'S RUN THE BEST AND MAKE THE MOST LOW END POWER WITH THE STOCK CATS ON AND NO SMELL WITH THE CATS ON, AND NO CODES WE MADE THE OPENING 3 INCH ON STOCK CAT'S SO BETTER FLOW SOUNDS AMAZING LITTLE LOADER THEN STOCK SRT BUT MORE LOWEND TONE. JEEP IS FLYING BRICK LOL
