Default exhaust pulse?

I posted this in the 2nd gen forum and got no answers. Maybe my luck will change. I've got an 01 1500 2wd with a 360. I purchased and installed the o2 simulator, removed the cat and installed a flowmaster 40 series. The truck sounds great except between 1900 and 2500 rpm's. In that short range, the exhaust sounds like a couple of cylinders are firing louder than the rest. I'm wondering if this is due to sound pulses or sound waves bouncing around in the pipes or the muffler, or if I need to do a compression check and see what each cylinder is pushing. I can get a recording and post it if it would be helpful. A friend of mine (who hates Dodges) told me that this is due to the fact that the Dodge v8 is an odd firing motor, unlinke a chevy or ford. I have a hard time believeing this because out of all the Dodge engines I've heard, none have sounded like mine. Please help me out here because I'm really getting annoyed with it and I'm hoping that this isn't leading up to further maintenance.

Ifyou can, do a compression test... if its relatively the same across the board, its probably the exhaust.

Do you notice the sound by the motor or at the tail pipe?

Without being able to actually hear what the truck sounds like, I cant really say for sure.

But I have not heard of firing problems from a 318/360 being really common, so I would say your friend is full of crap

never heard of that, are you saying you hear a misfire?
check coil-cap-rotor-plugs-wires for spark arcing lines.
Does anyone know of a forum similar to this one but for Chrysler-Dodge-Jeep Dealer techs only?
