Paul, I gotta respectfully disagree with you on the quality of that magazine article. Those clowns repeatedly keep echoing that old disproved wives' tale about increasing backpressure gives you more bottom end torque. Complete nonsense. They also appear to have difficulty understanding how to convert from firing order sequence to exhaust pipe flow/pulse sequence, negating some of their statements. Additionally, their "advice" seems to contradict Vizard's (an actual engineer, not a journalist) recommendations in his books.

I did not read it in its entirety.. i was looking more so for the sound difference for the op... i will go with your view of the article... and agree with what you stated..

So where is the proof of your uh "525 rwhp"? All I saw in your video is someone's red C3 making a bunch of needless noise. Instead of bragging about your car how about helping people in your Corvette Forum find and fix their problems? Oh yeah, with 525 rwhp how does your C3 pass the strict California smog tests?

1st Who are you??? lol... 2nd The reason I posted this, is i needed the sound.. yea the sound.. someone in my corvette forum wanted to hear what a 3" mandrel bend with X-Pipe off of 1 7/8" Kooks headers from a 427" SBC 650hp would sound, and this is it... they sound european exotic.. 3rd My HP and my car are very well known on the Corvette forum,,, ;and yes.. 525 RWHP, under 3000 lbs. This car races at willow springs, and 5 other raceways in southern California,,, and Smog, none of your business is it? you do sound like a California liberal...

Paul, “Candace Williams” is actually Michael Heathrow, AKA TooOldToRetire and a slew of other names. He has been blowing up my YouTube comments on my video I posted here as well. It seems since he is banned here, he likes to stalk us, then voice his opinion on our YouTube channels. I got 3 comments from him, then he changed IDs to Candace Williams. FYI

Now, back to X pipe discussion.
Anyone contemplating an X Pipe, make sure to use one that has a full flow at the X with an average size merge between the two sides. What I mean is, you don’t want the X to be a pinch point in the middle, a lot of the cheaper X pipes like Jegs/Summit brand Xs have the two sides tightly merged, restricting over all flow. Ideally, you want both sides of the X to be a full 3” and tied together... vs two 3” pipes that are just sliced and merged.
Dr Gas, Flowmaster, Borla, Corsa all makes full size Xs with no pinch in the middle.
