  • How will it eventually resonate? If it was going to "sound like flabby butt cheeks", wouldn't it do it all the time? Not understanding the comment about the stock piping.

    Our trucks sound identical at idle, the sound quality on the camera goes to piss on yours when you crack it. Yes they are both 5.3's but I imagine this one will work that Tahoe over.

  • If your engine comes w/ active fuel management, it drops to V4. Not 6.

    My 07' is a 5.3L, and it tells you on the display what mode it is in.

    I don't believe this option is available with the 4.8L motor.

    I wish they had engineered an overide button to lock it into V4 for the highway, I find it's too sensitive.

  • hahah funny thing is yours sounds pretty similar to this truck.....lol

see all

  • Which Flow did you install?

  • what model of flowmaster?

  • sounds great man....nice throaty rumble!

  • @bertdaflirt isn't it i4, inline because it shuts down one of the banks of cylinders in the V8?

  • hey man that sounds really good. Do you know what series flowmaster muffler that is?

  • @1KREEPAH3 yeah if you get the 5.3 model and it changes to a v4. yes a v4. not i4.

  • @andymiller71 that guys an idiot. it acctually sounds good.. 2.75 is a good size pipe if you think about it. if you get too big of a pipe it'll suck up less back pressure and put out less torque at lower rpm's.

  • How much that run you installed?

  • I have a Question does the 2007 chevy switch from using its v8 motor to a v6 when not needed?

    pls reply
