nothing you probably wouldnt notice too much, idk loudmouths are BADARSE and superloud, go with those if you dont care how loud it is

The Powerflo will be the most restrictive of the SLP exhausts. Like you said, it's only a few horses and you probably won't notice much difference. LM1's will flow the most, but are hella loud. LM2's won't be as bad, but are still loud. My personal favorite has alwasys been Magnaflow or Borla. They both sound badass on a 5.0.
