Not a surprise, especially since they appear to going to EFRA certified or nothing. I too hope the 9853 doesn't change, because that's my favorite pipe right now.

Hey Neal Smith, hows your 9886 stock????

Its sad because all the current pipes are noise regulation 3 chamber pipes... developed for noise reduction over performance...Here in North America we have no need for any noise reduction and it sucks to have European standards put onto us when its not needed...whats even better is the 3 chamber pipes end up not really being quieter so the 3 chamber rule is just a big steamy pile of useless poop ! IMO its more of a administrative cash cash grab then is anything about making the engines less noisy..So now all the racers are forced to run pipes that were not developed for optimal performance and efficiency but rather to meet a specific design characteristic that some yahoo's decided was better for sound reduction...I Would take their rules more seriously if they actually used a decimeter to measure sound, but they don't..useless rules resulting in less then ideal tuned pipes for these engines

on the dyno the 9886/9853 trump every other Nova tuned pipe on pretty much every Nova engine there is...bottom end, midrange and top end, the 2 chamber pipes perform better and make substantially more power...

IMHo this is a bad move from Novarossi and will be good for Ofna and Dynamite, even though 086 pipes are not exactly the same as the 9886 they are a very good alternative, at least that's what I'm going to buy when my 9886 will need replacement.

I've never quite understood why some people say the 086 is the ultimate power pipe. I've never tried a Nova 9886 though. I've had a couple (Ofna..) and tried them here and there, and they just never did anything for me. I also have a Dynamite 053 hard ano, which IS a good pipe IMO. 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......

Aha.. Sounds like I need to get me a 9886 then..

I never see them available over here. I've seen some onroad 9886's though..

Definitely do....

What do you even know about EFRA?

At the EFRA Euros in Sacile, Italy, this year, there were noise measurement taken on random cars, sound level was noted, brand of engine, pipe and car, and the results and statistics of these measurements were a topic of discussion at the EFRA AGM last weekend. You can go have a look at www.efra.ws.

So I'd say your claim on that is based on your lack of information, so you should get informed. And there's also a reason why this is being done, it's because all over the world tracks are being forced to close because people that live nearby are complaining about noise levels. Since we are limited by laws and human rights treaties, as to what we can to about these neighbours, the best option is then to try to make our cars slightly less noisy. That way we can still drive our racecars.

As to your claim about the outdated 2-chamber pipes, the fact is runtime decreases vastly with these pipes.
If with a modern EFRA approved pipe you would get 10 minutes of runtime, you will get 6:30 with one of those 2-chamber noisemachines you speak so highly of.

For those of us who actually race, it is somewhat important to get good runtime. We don't all just bash. A lot of us race.

your run time ideas are not accurate .... we have racers all over getting good runtime with both the 9886 and the 9853...now some pipes might doa little better on some days on some tracks but if your seeing a near 4 minute runtime difference between pipes you need to check your tuning procedures...

The only noise complaints we ever got was from our PA system which carried sound many magnitudes further then the engines..Same goes for the track in Edmonton, same deal...no issue with engine noise, big issue with PA system........I might not race but I owned a track for 5 years and have a very large number of racers in close contact with me who do race, so I am far from being the clueless basher some of you want to insinuate... I don't race because after a week of working on Nitro engines I am done for the weekend..if I raced I would burn out and end up getting sick of it, a guy can't do the same thing 7 days per week and stay sane !

If you race then you should enhace your tunning skills because if you can get a 3 1/2 more minutes of runtime with a three chamber pipe over a two chamber pipe then you should be way out of tune. 20 to 40 secs maybe with some pipes (not all) but no way you can get 3 and a half minutes more.

Which 2 chamber pipes get that poor of run time?

I've got an Ofna 053 and a Nova 9853 and I can get 10 minutes easily in truggy with either an Elite 5 or p5xlt.

So I got the 9886 for my Rex Legend 7 engine and wondering what would be a good manifold choice, we got a larger track but some jumps have short run ups. I'm also put this in a buggy. Thanks for any advice.

For a 7 port in a buggy I would use 41001.

Racers know why they pitted before low fuel in tank, usually 7-8 minutes gap in buggy , basher will never understand because a race tune is totally different.

Most argue about runtime but what matter is race pace, u can drive with low fuel consumption with Slightly off the pace
