i have a 2006 screw and i wanted somthing a bit louder....somthing that will NOT drone out on the highway because i commute 100km on the higway everyday, i want somthing you cant really hear in the cab..and will give it a little grunt outside...i was thinking of a si/so 70 series, just takeing my stock muffler out and replacing it with that, does anyone here have a 70 series on there truck?

If you run it out in stock location,the 40 series isn't very loud,and doesn't have much drone.

I have a super 44 and there is no drone in the cab. I can hear it if i hammer on the throttle but its not loud at all. Not nearly as loud as i wanted.

i had the same criteria as you, wanted no drone in the cab, but something with a bit of grunt. i put in a super 44 si/so with a 3.5 tip out the rear thinking this is what i wanted. its nice but too damn quiet for what i wanted but it fits perfectly for your description. I also commute about 100 km a day all freeway and do not even notice i have an exhaust that's louder than stock... which is good i guess

I have a 2005 Screw w/ the 5.4. Friday I had a Flowmaster 50 Series SUV welded in, in place of the stock muffler.

I am very pleased with the 50 Series SUV. I was worried about drone and didn't want an obnoxiously loud exhaust. This muffler is exactly what I wanted.

Zero drone at any rpm on my truck. At 70mph on highway you really can't even hear the exhaust in the cab.

When I start the engine it has a nice deep growl and sounds really great when accelerating.

If I recall correctly the SUV is about 8 inches shorter than stock muffler. When the shop cut out the stock they placed the flowmaster to the backend of the void left by the stock muffler and added a short piece of pipe on the inlet side. This moved the muffler pretty much out from under the cab. Local shop installed the muffler for $75. I bought it online for around $130.

I couldn't be happier with how it sounds inside and out.

Hope this helps.

You can buy the muffler for about 85 online, and have it welded in for probably 20-40 dollars...Do not pay more for 150 for muffler plus install if you are just swapping. Magnaflow is quieter and has better flow numbers
