People say that x pipes sound better with straight thru mufflers like magnaflows and h pipes sound better with chambered mufflers like flows. But in the end it's all personal preference. Good luck !!
xx9gt6xx said:Yeah I agree. The high-flow catted pipes w/ a glasspack-style muffler gives the Mustang a great sound that stands out from the catless regular muffler style setup. I'm a big fan of the catted pipes w/ a Magnapack or Loudmouth. But if you were to run no cats on either then :nonono:
