GMPP Touring exhaust 2007-2013

[Badbird2000]

I am sure someone here has this exhaust. I have been doing some research (here and Youtube). Can anyone tell me, does this muffler have any drone when the truck kicks into v4 mode? I'm looking at the Borla #19131346.

 

Thanks for any input!

I just put the equivalent "touring" system on my 2014, 5.3. If you get it thru a dealer it will have the flapper valve built in as well as a bypass pipe around the flapper. Borla absolutely guarantees that the system will be 100% drone free. I've found this to be true on my truck as well.

I had the touring Gmpp cat back on my 2008 5.3 and had absolutely no drone whatsoever. When I added the supercharger and longtube headers I switched to the gmpp sport muffler and even with that set up the drone in minimal. Nothing a few turns of the volume knob can't fix.

Thanks guys. I had a Borla on my F150, and it sounded good but droned pretty bad. From everything i have read, the touring one fits my needs. I have a 3 year old and we take one or two trips from,Tennessee to Florida a year. I want to hear it when i romp on it, but need it fairly quiet at cruising speed.

I had a Borla on my Trans Am that was pretty much wide open..
