[QUOTE="Jam421, post: 16193905, member: 110985"] I had a JBA X Pipe installed on my '13 which at the time had stock exhaust. I noticed the sound was raspier...especially at higher rpms. The X Pipe was on 3 weeks before I decided to order headers which I specifically requested be H Pipe. Can't comment on loudness as my mod back to H Pipe included the headers. If there's only a measurable 8-10 HP it really comes down to sound you want to hear. Raspier or Deeper. I'm now running the Corsa Sports behind H Pipe, Hi-Flo Cat American Racing headers. Folks disagree on mufflers making any performance improvement but Corsa Sports axle backs advertise a 8-10HP gain that I was surprised to hear American Muscle tech tell me they verified on their dyno. No matter what the claims your sound goals are likely more important. [/QUOTE]
