I've had my 3" single in-2.5" dual out flowmaster 50 series catback for about a month now, and I am considering replacing the muffler because I'm not too pleased with the sound.

I have heard great things about spintech and also gibson. What are your thoughts regarding a good, deep-sounding muffler that does not resonate as much as a flowmaster or as loud, but still sounds sweet?

I'm also assuming a muffler shop can simply chop off the current muffler and hook up the new one, while maintaining my current exit system (i.e., nice SS 2.5" turndowns behind each wheel)?

Try the Cherry Bomb Super Turbo muffler (don't start slingin' sh*t guys)! It is available at Pep Boys ($30 +/-) and has the best of all worlds. It has an awesome tone at idle, it's actually quiet between 2500 and 3500 RPM and lets you (and everyone else) know when you are in it!

My 2 pennies...

I had a Flowmaster 50 Series Delta Flow muffler
S/I D/O in my 04 quad. The drone in the cab hurt my ears (ear peircing!!)around 1800 rpm. Hated it. Got a Magnaflow s/i d/o #12258.
Still has some drone... but is 100 percent better.
IMO...I think the drone noise is worse in the quad's.
Gonna sell the flowmaster!

I had the same problem with my Quad. I think it's because the 2 vents in the rear of the cab are so much closer to the muffler.

It isn't the vents, it's harmonics!

Different frequencies resonate at different distances. Have you ever played a bass CD that sounds better outside of the truck than inside? The lower the frequency, the longer the wave length. If you could move the muffler closer or farther from where you sit, the drone would go away at that RPM and would be heard at another (muffler closer=drone at higher RPM, muffler farther away=drone at lower RPM). The key is to find a muffler that produces the undesireable "tone" at engine revs that are above or below normal cruise speeds.

You need to be careful, as exhaust sound is as personal as style preferences.

I replaced my stock muffler with a glasspack last fall. The "get on it" sound was great, but it droned badly at highway speed, and had some sort of resonance at around 1700 rpm. I replaced it with a Magnaflow, no drone, deeper sound then stock, but quieter then the glasspack. The Magnaflow will stay.

Note that both replacements were muffler only, single 2.5" in, single 2.5" out.
