thanks!
+1 how good are the p3xs and p5xl?compare them with the above if you can!
n21b09 is supposed to be the new 3 port with the purple head , doubt there was any running changes from the limited besides the head but we haven't seen them in the us yet

somebody needs to order them in
pipes are pipes , they work the way they are designed to work on most engines you put them on but there are some engines that dont like some pipes . and contrary to some peoples beliefs , you cant just throw a low end pipe on a 45,000 rpm engine that is designed to scream and expect it to have low end
as far as the new p5xl , it hasn't been ordered for us market yet either .
good to hear from ya again btw
