'02. Knowing what I know now, it would have been much faster. By the time I sold it I had an underlying issue that I was not able to diagnose that also didn't help. I suspect it may have been a blown head gasket (a friend driving it had smacked the rev limiter HARD more than once)

I take it the Jeep under your "My Jeep" section was that Jeep or did you get another 4.7 02'?

My commuting at the time dictated that I get something (anything) that got better gas mileage so I scored a freebie '97 Honda Accord from my uncle. All it needed was 2 new tires. That being said it's like driving a Xanax on 4 wheels.

Sometime this year I plan on upgrading to something else.

While I agree with what you say, I'm also sure you realize that most people who buy them aren't aiming strictly for performance gains but buy those kinds of parts mainly for the audible experience and feedback you get from driving with it equipped.

Both were stock as this is usually the first thing I do. Both responded in about the same way. Disappointing............. at first,but I was expecting this on the second one. Both vehicles seemed to lose a little in the seat of the pants acceleration category. I don't have numbers to back this up but it was enough that i could notice it. Now on to things I can prove. We have had the same 21 ft Stingray cuddy boat for 12 years and I have towed this boat until last year with 4 different vehicles. Two of them being 4.7's. We go to the same lake about 7 times a summer about 60 mi.away. On the way home from this lake is my test track. It is a 2.5 mi. grade up this godforsaken cliff called Tussey Mountain. The boat and trailer weigh #3800. Also two different mufflers were involved. Dynomax on the Durango and Flowmaster on the Jeep.With aftermarket exhaust the Durango gained a consistent 3 mph on this hill and the HO came in at between 4 to 5 mph probably due to the fact that it breathes better not exhaust choice. So....for what I do with my 4.7's freeing up the exhaust is a no brainer although I don't think it cares what brand name is back there. My take on it is that the 4.7 likes back pressure down low in the rpm band(explains out of the hole loss)but responds well to a free flow exhaust higher up in revs. The moral of the story here I guess is if you're gonna do most of your driving under 3k all an aftermarket exhaust is gonna do is make noise.After that it starts to make a difference.


I should probably clarify my original post.

There is something to be said about throwing a "race" muffler on a otherwise stock vehicle. This of course will vary from app to app, and also muffler brand/design, but in many cases a race muffler will either sound like a straight pipe (undesirable) in the otherwise stock system, or you bring about other "ugly" acoustic events that would otherwise not be there. So that leaves you with not only being loud (which isn't a big deal), but you could have a setup that is still plenty audible for not much more money, have the added benefit of performance, and have a much more acoustically pleasant sound.

Re: Buying new muffler, Anyone recommend anything?

This is Hilarious! I started out trying to make a sound clip of the Flowmaster for the Riechminister and it went downhill right from the beginning

@FlyinRyan: Well outside the "race" kind of muffler thought, any certain product you would recommend and have had good experience with?

@CheapJeep: I appreciate your concern for the video, not every video has to be perfect to convey an idea or experience. Also, is that the Flowmaster Super 50 or a different series?
