True duals won't make a dramatic tone increase over a single muffler. Matter of fact by slowing down the exhaust systems velocity with a loss of static pressure, you aren't getting the full heart tone of the muffler taking the force of the single exhaust to 'filter the sound'. In short, the duals will be more aggressive under WOT, and sound the same at low rpm and idle. If anything, the idle will sound more 'dual-ly'.

I love the well toned sound of the Magnapack over the dual Bullets I had on my last truck, but the raw aggressive attack that the Bullets had was quite nice. I am loving the deep rich tone this Magnapack puts out, but it could be a little better. By that I refer to the rasp Magnaflows put out at WOT. Borla is the best of both worlds but the deal at the time for the Magnapack made it the deal breaker. If you decide to change your tubing to dual, or just change the muffler, the Bullet is now available in stainless, and is very well priced. I wouldn't hesitate to go for it if you enjoy the sound.

That is exactly how I want it. Do different year trucks sound different? Its same engine.

Considering he had the 2 larger cat design, and mine had the 4 cat system with the rear two removed, I think they sounded quite similar. If anything mine may have put out more decibels.

My step-brother's truck is a '99 5.4 with a 3" system and an original 40 Flowmaster. I have a video of it here.
