Maybe a used set of schricks will appear when I'm really in the market
      Just remember its usually ten times harder to find positive information then negative on the interwebz. People tend to not comment about products they are happy with.

      Port matching is almost 100% a waste of time. That area of the port has the highest flow numbers of the system. The area you actually make power is around the valves.

      Eh, Based on things that have already been said, I'm really not expecting any notable gains. I mean, its been noted several times that even headers barely offer anything....so I'm more or less just going for rasp reduction now . Plus, this is pretty much a freebie for me. I got a set of manifolds at a reasonable price, I'm doing the work myself, and I'll have to remove my existing manifolds at some point so I can swap in a replacement downpipe (since the flex joint on mine has seen better days)...

      Still waiting for the gaskets to come in so I can mark up the manifold ports. Right now I'm pretty sure about how much I can remove, but I want it perfect so I'll wait. In the meantime I started to play and it was surprisingly easier than I thought, but this is going to take some time

      I ported a 2 liter head, the downpipe, and the intake manifolds. Exhaust manifold I bought ported and polished for a song and dance. At first it is tedious, once you get the knack it it fun. I kinda want to port my friends audi 90 exhaust manifolds while he's rebuilding his head.

      knee deep into things now...I lucked out and the gaskets came today. It's actually a lot easier than I though and is somewhat fun/zen Just on a lunch break now, pictures later!

      No joke. Seeing the gasket on the manifold, there is a TON of excess material there. I would imagine that it does more than a little bit to disrupt flow. I doubt you'll feel much (if anything) on the butt dyno, but if it sounds better, it was absolutely worth the time and effort.

      take a foot long straw. now blow through it. now make one end of it bigger. notice you cant blow anything more through it. same thing. the port is in the 93-95% efficiency in this area, but closer to 50% around the valve. It doesnt matter how much material you remove in the port, its not fixing the problem (and may actually be making it worse by dropping velocity).

      your two statements make absolutely no sense together. If they are inhibiting flow, then why is there no additional power..... thats right, because they ARENT.

      p.s. its likely that power is decreased from opening the throat of the port.

      I said they would not yield MAJOR gains, say like 30 hp. I bet one could see 3-5 hp from doing this....noticable, probably not, but thats not why I'm doing it. So my statements do make sense. Will the exhaust be less turbulent resulting in a smoother less raspy sound, more than likely. I dont know how you can look at those pictures and tell me that there is no point This all said, your entitled to your own opinion as am I


      PS- Your straw theory would hold true for porting a head as well right...

      perhaps you should read some books on gas flow, you may find some enlightenment (hell there are lots of great tech articles on the net). You seem to have made up your mind, so i wont waste your time with facts any more. best of luck.

      Smartest thing I heard you say yet. Please know that I am a humble person and will absolutely admit if I'm wrong....if I put these on and I lose power, it doesn't reduce rasp, I'll be more than happy to admit you were right. Until then, all I can go on is what I believe. Vaya con dios

      I'm going to wait on Dyno results before even thinking this is a good idea.

      I'll say this, hogging out that much material that was blocking the ports before definitely won't HURT anything. The gains will be minimal, but that's how mods started in the first place. A few HP here, a couple MPG there, whatever. It's been shown that everything on the exhaust side is a restrictive mess, so any improvement that can be made is a check in the W column.
