i have Magnaflow exhaust on my F250 (with a 5.4) and i like the sound. but for my Shelby i want a more aggressive sound. what is the difference between H pipe and X pipe? are Mac exhaust any good?
Yes X-pipes do make slightly more power due to the exhaust pulse/scavenging effect, but nothing noticable on a 500 hp car.Again, this is from what I have read, but there might be a ~5-10hp difference between the two, with the x-pipe giving more hp. I dont have dyno results or anything to back that up though.
Could you post a vid of your system please? You have the exact configuration Im thinking about going withYes X-pipes do make slightly more power due to the exhaust pulse/scavenging effect, but nothing noticable on a 500 hp car.
On a side note, I LOVE my KRs. Best exhaust note I've heard for the GT500 IMO. I have the stock X-pipe. I've never heard the H-pipe configuration in person so I can't comment on it. From what I've heard on sound clips, the X and H sound almost the same.
