Hey there fellow OS users. One the weekend I tried the short manifold with the HIPEX pipe. Results are not totally conclusive but the first thing i did notice that the pipe did give a bit more top end or the OS OEM pipe set, run time was much the same. Power band delivery was a bit earlier with the hipex pipe.

This weekend we have another race meeting and I will try the medium manifold and report back the results. I will have better data after this weekend as I can give a comparison on all three pipe combinations.

Sorry if this is not a totally comprehensive post on the results. But so far if you are keen to try these HIPEX pipes and manifolds, I would no hesitation in suggesting anybody trying these. They are excellent value for money and are very well made.

Stay tuned for another post after this weekend.
