MSDS Headers

Any good? worth the money? ceramic coating comes free, if you want it... (which i do...)

http://www.msdsinc.com/exhaust_1.htm

a quote from their site...

"Dyno tests have shown a minimum 14% horsepower gain time after time. Our 928 Porsche headers showed an astonishing 23% horsepower gain... on a stock engine!!"

928? You have a 944.

right... but that's just a quote of the site about their test on a 928... and if the 928 gained that much, even if mine gained the supposed 14% HP wouldn't it be worth it?

Your 944 would see an improvement but not at the level of the 8 cylinder 928. You may not be able to measure the improvement.

Besides the 928 has room for improvement over the stock header design unlike the 944.

actually, i talked to one of the members on here, and he has them, and he said it was noticeable difference, especially in wind up. but, do you think 207 bucks is worth that little extra? i was thinking, get those headers, and get wilk's chip. the only two performance mods i can think of... other than things like suspension, sway bars, etc...

It's your money. Unless someone dyno's their car before and after, any reported improvement is just opinion.

I noticed at least a 15 hp improvement in my car every time I would wax it.

well, wilk, instead of my money being wasted on headers it will be guarenteed in your pocket... as soon as i get payed... but i was planning on getting your chip first anway...

BTW, how much were those stahl headers you mentioned?

SoCal and FR, I value the input from both of you, but you act like there isn't much room for improvement over the stock exhaust. Are you talking about the cast iron or the tube headers? The cast iron look to me to be well designed, but the tube manifolds did not impress me at all. The welds mounting the primaries to the flange need cleaned up, and internally the junctions of tubes were pretty poor in my opinion. I would guess that the cast manifolds flow measurably better than the tube manifolds. Which manifolds were the aftermarket headers tested against?

I don't think you are going to gain much from a 'better' header unless you have had some major head work, intake, and fuel management on these cars....

Those are not cheap options when it comes to these cars.

You have to get well over 300rwhp on the 951 to actually begin to see the intake/headers/head as a limitation so I can't see what you could really gain on an NA.

but thats just my 2.4 cents.

I have a set of the stock tubing headers off of a later model. I found very poor workmanship with in the headers. One of the joints was restricting the other tube at least 30 to 40 percent. Wish I had a decent digital camera to post a picture.

My experience with headers dates back to the 60's and the burgeoning drag racing scene. Being a tech head I read everything I could and helped make many header sets for everything from Corvairs to hemi heads. It's surprising what works and what doesn't.

The cast iron exhaust is pretty much the same geometry as the steel tubing. Just a bit heavier. So, yes the tubing headers are better than the cast iron because of the weight loss.

Headers

Two things:

1) I had the Bursch headers on my 944NA. They are the biggest piles of crap ever! Horrible fit and finish, and they did absolutely nothing except kill my midrange.

2)Take a look at the 944 spec guys. I beleive headers are legal....however pretty much every car I've seen runs the stock headers. It is my understanding though that the later 85.5+ year cars had stainless headers which are lighter...so that may be worth something to the racer crowd. The reality is, these spec guys are trying to get every last HP out of the 944NA and they aren't running headers.....that should tell you something. Oh and one of the top cars posted a 132RWHP dyno chart too. So there's your goal for a limited budget.

Hugh, do you mean that the cast iron manifolds have the same restriction as the tube header, or that the restriction doesn't affect performance?

In comparing the cast iron with the steel tubing I didn't see any noteable difference in the internal geometry. I did find that one of the tubes on the steel headers, cylinders 2 and 3, was protruding into the other and causing a noteable restriction. I was shocked that Porsche would have let this error get past first inspection.

I wouldn't call the 944 exhaust restricting. It's one of the best flowing "stock" exhaust systems I've seen on these year model cars. Not much you could do to improve it given the space restrictions on that side of the engine.

You also have to look at the fact that the MSDS headers are 4 into 1. Which means you have to spend extra bucks getting a custom cat welded in and even cat back exhaust done.

Collectors, 4 into 1, are great IF you run the exhaust wide open. This is not a design that has any benifit with an exhaust system stuffed onto it.

Not having looked at the Stahl's I would bet that the reason these have an advantage is the bends coming out of the head are as large a radius as possible with or with out a collector.

Hugh, I know exactly what you are talking about on the tube manifold. That is the design, and I was also very disapointed, there isn't an obstruction like that in the cast manifold, so I prefer the cast to the tube.

I had to go out and look at it again. Maybe these were made in Brazil.
