I didn’t know you could remove the cats unless you replace the whole pipe from the flange where it mounts to the head all the way to the collector. I wish magnaflow or flowmaster made a better exhaust from the the head all the way back. I’d be happy with just ditching the cats in favor of a custom fabbed pipe that gets rid of the cats. As free flowing as it could be from there to the stock muffler. To me the factory muffler is the best sounding because even all the big names sound like junk due to the V6. I plan on supercharging after my truck is payed off, so hopefully my stock muffler on a free flowing exhaust won’t be a hindrance.
Well at the time I couldn’t afford a Hemi. So I was limited with my choices due to credit, etc. Going through the certified pre-owned there wasn’t any available anyway. Fuel mileage is hardly an arguable topic as there’s guys coming out of the woodwork getting 20-22mpg in a Hemi. I just wanted a truck with four wheel drive as I wanted to get back into hunting and fishing which I haven’t done either since before i joined the Army back in ‘01. So my Camry just wasn’t going to cut it anymore. I also have a ‘91 Eclipse GSX pushing 475/380, daily driver that gets 29 MPG. I just want to have a project on a V6 Ram. Something more than a CAI and a canned tune. My original plan was to not really do a lot to it but that plan went out the window. I’m a gear head, can’t help it. Hind sight being 20/20, I wish I’d have just waited a bit and got a V8.
the Ram 3.6 is a pretty well *optimized* package, so there's not too much room for *easy* improvement, which is actually good
1. 3.6 uses the same 3" exhaust system as the single exhaust 5.7 so there's PLENTY of flow already there;
2. the 'Y-pipe' on the 3.6 is a MUCH nicer design than the 5.7 crimped POS so a new Y-pipe or 'true duals' wouldn't add much Hp either
3. the 3.6 uses the same airbox and air filter as the 5.7 so plenty of flow there too; the factory design is a 'CAI' also..
a 'pedal commander' doesn't add any power at all.. just makes it *feel* more responsive.
that leaves 'tuners' as pretty much the only 'bolt-on' ;
or a true 'ram-air' would help at highway speeds ..
A 4x4 Ram weighs 6,000 lbs. It's already kinda remarkable that a motor smaller than a slant six can move it at all. If you want better mpg, you probably need to relearn how you drive. Especially important, I think how fast you drive on the highway. Anything over 65 mph will cause mpg's to drop like a rock.When I had a 2005 hemi Ram, I spent a fortune on performance parts, cams, headers, cat delete, Vararam intake, nitrous, on and on. Still, with all the extra hp, mpg was never as good as stock. It would go through rear tires like nothing. Now I drive the 240 hp Ecodiesel and love it.

Fella I have a 3.6 Grand Cherokee Limited with a $50 K&N Drop in and a Diablo DCX handheld tuner that I bought used for $130. I then got an Overkill 91 octane Tune for $99.
I don’t have dyno results or timeslips but it rips pretty good. Easily gained +20whp from my estimates. I had another pick up that I did take to the track that ran low 15’s and my GC could kill it off the line and on a highway run from 40-110 it could put 1+ car lengths on it.
I think hemifever does custom 3.6 tune files also.
