Ive had one, no complaints really. no longer in use due to bigger kit.. Good luck if you buy it!

 

I've talked to James at Muse and he's told me that the main reason they didn't have the manifold port matched to the gaskets is the fact that you won't benefit from having large ports on the manifold that aren't matched to the head.

The muse manifold is ported so it matches the head outlet, not the gaskets. Porting any larger than the head outlet causes turbulence, not the other way around.

The same goes for most other reputable shops (BUSCHUR DOES THE SAME THING).

If you look at this manifold and put it next to a ported bushcur it's the exact same thing. The runners are ported out deeper into the manifold and most of the work is done in the collectore. Saying it needs to be ported more is like saying that the guys at buschur don't know how to port a manifold.

 

So I am not a "reputable shop"? ok. When I said I spent time to port the muse manifold I was referring to the hotside end of the turbo

I wasn't going to post my pictures of this wonderful muse manifold. You are obviously linked to the company as you "push" them here. You might want to become a vendor to keep up with all your advertising of this product .

Now, the evo community can see for themselves the "quality" or lack of for this manifold and judge for themselves if this is as good as a ported manifold by a "reputable" shop hint PPI !

Here is the muse manifold as it was sent to me by a customer. You tell me, does it look gaske matched? That is a definate no. Slightly better than stock, but it is NOT gasket matched or even close.





Here is the manifold after I gasket matched it. Let Evom decide for themselves


Cheers everyone, facts are facts

 

Very nice work. I have seen one of the manifolds myself. Looked like a half *** job.

 

Show them the front and then compare it to this.

 

Damn, nicely done....

 

Thank you sir

 

thats a great looking manifold. i was looking to port my manifold, that work looks better then most ive seen pm price and when you can do it revmoto.

 

Looks real good.

 

I'm all for facts and I'm not trying to start any arguments. I also didn't mean my comment to infer that you weren't a reputable shop because we all know you guys are great.

I see that collector was opened up a bit to match the gaskets but there are a lot of people who just port the manifold and not the hot side of the turbo (turbine housing). The Muse is designed to flow with the stock turbine housing. Gasket matching would make perfect sense if said gasket matched the stock turbine housing perfectly, which last I checked it did not.

I would disagree in saying that the product isn't quality based on the fact that it wasn't over ported.

I'm not directly affiliated with muse, I was just given a good deal on a good product and I recommend that product when people ask for recomendations, no more no less.

 

Just out of curiosity, is that manifold gasket matched or are the runners matched to the ports on the head?

 

The runners are gasket matched but shaped similar to a velocity stack to be turbulent free. The stock head is larger than the manifold slightly. Saying gasket matching a manifold adds turbulence is wrong. Port matching the turbine side of the manifold and not the hotside will add turbulence. I suggest porting both for maximum gain though.

 

That's what I was attempting to explain, which is why I asked TTP if they could elaborate on the port match on the collector & turbine inlet.

 

Well it is quite simple. You port to reduce the turbulence of the unmatched ports to begin with but if you make the ports even larger on one side you are further increasing the impact of air against the original port. Its not that bad though. You wont lose any power from it.

 

But why do you recommend it? It doesn't even remotely compare to the work done by Buschur or PPI. Here's my Buschur stuff:
