I have a short bed truck with a 6.0/4l80 cam only. Installed a super nice exhaust system that is long tube 1 7/8 headers and all 3" pipe with x-pipe and mufflers like magnaflows with tale pipes out the side behind the tires. Problem is it sounds awesome until you hit 2600-3500rpm and you get a cackle like straight pipes in that area. Anyone have a similar set up or had this problem before? Looking for options to get rid of the nasty cackle sound. Thanks
