Iíve done the experiment at the track. 03 Mach 4V in a 99 chassis, NA, stock motor except for intake work. Kooks LTís with the Kooks X, dumps welded onto the end of the X. No cats or muffs. Collector.......X. ET just a couple hun better with the X on vs open headers. The X with the dumps as a unit probly weighs 25-30 lbs, so tough to see that in ET, but I did see a more significant difference in trap speed. Close to a mph pretty consistently, which would indicate car made more power with the X, especially at 6000-6800 rpms. And sounds awesome. Open headers on that 281 cu in. 4V kinda sound like axx.
99 coupe. C4/8Ē 5000 stall w/2003 Mach crate motor FRPP stock N/A, Kooks LT's and X,dumps no muffs. 4.56's

Coincidence. A convenient and overused word for the mentally lazy.
