robbins05Z71

I'm looking to see anyone/everyone's input on the 70 Series Big Block II muffler. I have a 05 silverado Z71 with the 5.3. I am looking at a the Flowmaster kits (I can get then at cost), and the exhaust shops in our area suck, so a custom set up is out. The Dual out the Rear or Dual out the Side American Thunder kits come with the 30 series mufflers and the Force II kits all come with a 70 Series Big Block II muffler. I think the 30 series will be too loud and the 70 series will be too quiet. What is everyone take here?? I'm lost on what to choose. I am looking for loud outside and quiet inside, i know the best of both worlds. I was looking towards the 50 series SUV, but that does not come in a kit. Help anyone.

if your looking for loud outside and quiet inside your looking for corsa sport....its expensive but it has the best of both worlds.

I Like The 40 Seires Delta Flow With 3 Inch Single In/out, Just Run It Over The Axel.sounds Good And It Isnt That Loud Inside With Cats. Without Cats, Well Thats Anoher Story, Real Bad Drone.

the 70 series will be quiet inside and a low rumble outside. even more so if you keep the cats. if your gonna keep the cats i would go for the super40 series.
