Way to many variables there. They make several different series of flowmasters and many lengths of glasspacks that effect sound greatly. If you took the loudest of each though a glass pack will be louder,you can get them so small they will basically just sound like a straight pipe.

I had dual exhaust on my 99 Silverado with an 18" (I think) glasspack on each side. After about a year, it was LOUD!!! The packing inside was gone so it was basically a straight pipe. My parents could hear me in the house with the windows open accelerate on the highway in the mornings from 2 miles away. I had 3" tailpipe with 4" tips going straight out the back, so it was a nice deep rumble. You could still have a conversation without yelling inside and still let people know you are coming.

The rumble has more to do with the tailpipe than the muffler. The bigger the tailpipe, the deeper the sound. A 3" tailpipe will sound night and day different than a 1.5" tailpipe. I would just go talk to your local muffler shop and see what they recommend.

this is kinda related. I want to get a different sound for my 99 Jimmy. but I don't want to have a whole set up. can I just swap out my stock muffler for a glasspack or flowmaster??
Yes,since you have a V6 though I wouldnt get anything loud or it will sound like crap. Maybe a flowmaster 50 series or a turbo muffler of some sort just to give it a little rumble.

Ive straight piped, glasspacked, and flowmastered my Blazer. Flowmaster BY FAR sounds the best. Cat back custom bent 2.5" pipe with a 40 series. The straight pipe and glass packs made the truck sound buzzy, as V6s often sound.

For 6 cylinder, go with Magnaflow. They give you a not-so-ricer sound. Flowmaster and glass packs sound like a ricer ( most of the time ) when put on 4 and 6 cylinders.

Honestly, I think saying your deciding between flowmaster and a glass pack is dumb. Glass packs are for if you want cheap noise. Flowmaster makes a good exhaust that is flow tested to keep power either the same, or get a small gain. Also, in a lot of places, glass packs are illegal as they are a straight through design.

My brother has a '94 Dodge 2500 V10 with dual Thrush glasspaks and it is pretty darn loud. He first put them on with his cat converter on and it was probably not as loud as stock. It sounds pretty throaty, maybe a little too much for my liking. He also did get pulled over once for loud exhaust.[LOL]

Start your truck, let it warm up, then rev the crap out of it ( dont blow your motor though ) and see if the cat turns red, or gets extremely hot.

With the exception of true muscle cars, I'm not a big fan of flowmaster on anything else. There's a new charger running around here with flowmasters that sounds like crap, and I've heard a few other newer vehicles that really don't sound good. So, especially on a V6 I'd go with magnaflow.

I took the exhaust off my truck and found the cat was completely destroyed inside, this was under 100k miles too.

You dont have to do that to see if your cats plugged just start the tuck and go by the tail pipe and hold your hand over it if it has enough pressure to push your hand off then it's not clogged. But if it is hardly pushing your hanf then it's clogged alot easier on the motor that wy and doesn't require revving the piss out of it.

I woudnt go magnaflow for a 6 cylinder. There nor very loud as it is. I have a cat back system on my V6. Magnaflow highflow cat but a thrush turbo muffler one in two out with 2.5" pipes and 3" tips sounds good and better then some V8's.

Thanks for the responses guys. I really like the sound in that second clip powersledder. That's basically what kind of sound I'm looking for.

Do you think I could just get setup? like list setup but with flowmaster 40s? how do you think it would sound?
