2004 Dodge Ram 1500 4.7 magnum flowmaster exhaust and drive by

@unchainedbass Do u think this setup could fit my 06 dodge ram 1500 quad cab with the 4.7?? also how much was urs and did u notice any hp increase??

[unchainedbass]

@rogeliogallegos76 We'll this is not a 'bolt on' system. I went to my local muffler place and had them bend me up a system. Im sure you can get the same sound from your 4.7, too bad there's nothing you can do to get rid of those extra 2 doors :P

Hey I was going to ask you, What did you do about the check engine light that comes on when you remove your cats? How did you remedy that??

[unchainedbass]

@RyanH0000 Well I haven't solved that yet, for the moment I just clear it every so often with my superchips tuner. My PLAN however is to TRY and make a couple of "dummy" sensors that send back a constant reading of what the O2 sensor might report after the truck has warmed up, weather that will work or not is a mystery but its worth a shot. I will definitely post a How-To video if i get it working right

@unchainedbass Cool man, That'd be awesome. I think i'm gonna pull my cat off today. Does your truck still work fine with it off?

[unchainedbass]

@RyanH0000 I would be cautious cutting them off, i'm still testing mine out and im pretty sure (not 100% yet) that my gas mileage has plummeted after taking them off(shot in the dark im guessing less than 10mpg now) i should know by the end of the weekend (gotta burn through a tank of gas to see). Other than that, YES the truck runs perfectly and has a little more get-up-and-go between 2,000 and 3,500 rpm but I don't know if ill keep it that way.

@RyanH0000 Well I went and bought 2 new upstream O2 Sensors (before cat) and replaced the old ones. Took the downstream (after cats) out of the exhaust did NOT disconnect them, wrapped the really tightly with aluminum foil and zipped-tied them out of the way. Took the old O2 sensors and put them in the downstream holes. Used my Superchips tuner to clear the code and never had an issue since.

@RyanH0000 Sorry for taking so long to reply. I have since re-install the cats so I can pass inspection lol. Probably wont take them off again but it sounded good while it lasted.

nice mail it sounds good did you get the truck brand new or used? i know you have had it for a while

[joeldude76]

@joeldude76 i mean man lol

[unchainedbass]

@joeldude76 bought it used 2 years ago with 75,000 miles on it from a 5-star chrysler dealership (basically means its mandatory they overhaul the truck when they get it as a trade in, new oil and filters, spark plugs, tranny fluid, rear end fluid, and just about anything that can be maintained, the whole 9 yards and then some) Its been a great truck
