Hello ! I'm getting ready to start doing my lift. I have the boomerangs on backorder ? Am considering getting the Terraflex instead ? What experience has anyone else had ? Also I've already bought a Walker SSTL Quietflow muffler. Thinking about going to a Magflo 40 ? Running a Magflo hiflo cat, 2.25" pipe, Northeastern SSTL 409 mandrel bent. Lift is OME CS033RB 2-3.5" with OME shocks, long travel. ACOS adjustable front, JKS control arms and panhard. Thanks for your thoughts, experience and opinions,,,
