That I am not sure of. You would have to compare prices and power gains. I went with the JBAs because they have the bigger primary tubes (1 3/4) and I went with the ceramic coating which helps reduce the amount of heat coming off the headers but these list for $795. I found them on Ebay for about $400. These headers only provide about a 10 hp gain by themselves but with the JBA exhaust they claim adds about 30HP or so. I used them because ,again, I have the freeflowing exhaust. Several others are much cheaper but again you must compare.
