Aftermarket Exhaust Without Drone / Resonance
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!!

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!!!!99 K1500 Suburban LT "THE BEAST"

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!Adam
