I wouldn't call it a big power pipe though either. It seems more a super easy to tune pipe with a generous tuning window(when I used to have issues tuning an engine, I'd throw the 053 on to sort it out..), with kind of a big gaping mid-ange, but nothing special in terms of power. Looks new after years too..
I don't have
tons and tons of experience, but the pipes that have made me go WOW were the 0801 on the Argus and Alpha, the 2063 on the Nosram(Picco), the JP-2 on an LRP Spec 3 .28, and the 2041 as probably the best all-rounder I know of. I have two 2058's which are OK - good for racing and the track, in that they seem to get up to top-end really fast - but they wouldn't necessarily be the pipe I'd go for if all I wanted was power.. But then, for me anyway, neither would the 086..
the 086 are very different then the 9886.....they may look the same but the dyno results are quite different, more difference between a OFNA 086 and a 9886 then there is between a 9886 and a 9853......... the Nova branded pipes are their own unique pipes, the other copies are not the same pipe in perms of performance and power
Another issue is manifold..with these pipes having the wrong manifold can dramatically reduce the the power of the engine.. pretty much across the board the Nova 9886 outperforms the 086 pipes, only one time did I find a engine where the OFNA pipe did better , but that was more to with a unique modification tot he engine rather then the pipe itself........typically the OFNA pipe has a slightly higher mid range torque peak but a narrower powerband with less bottom end and substantially less top end.....a engine yesterday made 4.05 HP on the 9886 with 145 oz/in, the OFNA made 3.3 HP with 150 oz/in ..the 9886 had better bottom and a much better top, the 086 had a a narrow peak where it bumped to 150......
