5.7 Hemi "issues"?

Yeah..my o6 with MDS just turned over 16,000 miles. Runs awesome. Has the typical valvetrain noise, but that is purely hemiesque. The lifters make some noise, but remember, they are rollers. I have a AIRRAID cold air unit and Magnaflow dual 2.5" exhaust on mine right now. I like the sound, but i may eventually switch to the flowmaster unit that is specifically for the lil elephant, as the magnaflows are still a little quiet and don't sound as loud or growl when at idle.And its true..the aftermarket exhaust does make the thing sound a little weird when the MDS goes on,but it doesnt bother me. The MDS only seems to run when you are barely on the gas anyways, so it doesnt really matter. Besides, if people(namely non pentastar enthusiast) are dumb enough to think that it is a piece of crap that sounds like its loosing compression for no reason, then whatever. Atleast i know of the beast that lurks inside when the gas is floored, even if they don't. Thats what counts. Has anyone heard what the new GM Displacement on Demand system sounds like with exhaust..not good in short...(sigh)..ok...my tirade is done..i think i will go out and beat the crap out of my mopars now..lol.
