    I recently purchased my '07 NBS Silverado crew cab 5.3 litre. It is bone stock. I have GRAND PLANS to upgrade and modify!! One of my first projects will be to upgrade the CAI and Exhaust, and then tune. The one thing that I don't want to do is repeat the problem that I had with my previous Hummer H3. I installed a Magnaflow catback system. The quality, fitment AND price were excellent. The drone / resonance inside the cabin was horrible especially at low RPMs. I searched a little and found some information, but I thought it would be a good idea to start a new post and generate some discussion about the various systems and how they rate as far as in-cabin noise. I'm sure ALL of the systems sound great outside the truck, but are you satified with the interior sound?

    Thanks in advance for your input!! :great:

    My magnaflow was the same way for my beast, it rotted off in only three years so when i got new exhaust i went with a flo-pro muffler and love it. Better seat of the pants feel, no drone and a way better sound, and half the price!!!!

    I had Borla exhaust on a C5 Corvette. Nice quality system. Anyone here have a Borla system on their truck?

    I also had a B&B Exhaust (Billy Boat) on a different Corvette. How about their truck version?

    I've commented on this a few times already, I've had 2 Gibson systems and in both applications (5.7L and 5.3L) there was no cabin drone at cruising speed. They have a nice rumble at acceleration and at wide open throttle it roars!
