SLP twins... how are they holding up?

[Clarke673]

I remember when the SLp twins came out, that many people had fitment issues and they were a pain to install. BUT, a lot of people seemed to like the performance gains. I am wondering (after a year) How are these pipes holding up and would you buy them again/recommend them.

i have cpi twins on 09 assault awesome power . . . and i heard slp is tryin to make a lower compression head to run the twins at low elevation.

I run them at 2000 feet, 50% race but the head was cut for higher compression by carls, I think they would have to make a different set of pipes for it to run good on pump at lower elevations, with the updated head compression is not a problem. As for fitment, well its worth it, they fit snug, stay put but ya cant install them in 15 minutes. with creativity you can get them in without pullin the cylinders but it wont be fun.
