i personally have never had a bearing failure on any OS engine..VZB, Vspecs, .18's...but when i rebuild them..i do replace the os bearings with a rb c5 bearing..rear bearing only though...still use OS front..

and the 2050 is the only pipe to go with...the only other pipe i would run is a 086....as it seems to yield same performance..but has slighly less run time
