Thanks everyone and 15WHP gain with 15"s on compared to the 18"s on the 425 run soo yeah the O2 housing is worth an honest 15WHP gain MINIMUM! I had C16 in and I have a cat as well so it could be much more if I ditched the cat. Well maybe Scotty will come through for a straight pipe side exit**Hint Big wishful Hint** BUT I think the really impressive part was my WTQ went up by roughly 30!! and spool was faster then before..Scott had to leave early due to work
but we got to play with the fuel alittle more the AFR's of 16
Got fixed (Dumped about all fuel on the 750's by redline and still running a bit lean..needing possibly a bigger pump or run twin walbro's....??
