Glen, I can't speak to hp with data. But I really like the sound and feel of Euro exhaust, 85 manifold pipes; Y into 3". Obviously there are an unlimited of configurations possible. Mine was too loud, so we grafted-in a 32 V cat -- that calmed it down just enough.

That's cool that you have the CIS and electronic injection versions of Euro.

Would true full length headers be of interest to early (84 and older) 928 owners?

No one seems to know if the OBX product can be massaged to fit our early Porsches. With a price so low I'd expect problems..

Be nice to have true headers w a big diameter Y collector.

I know a guy (Pete) who builds custom headers for Hot Rods and he's excited to make something for the 928. He has agreed to provide the rough bent tubing for me to build a prototype.

He needs a drawing or a prototype to give us a rough price.
I have let him know they would need to be affordable otherwise few would buy them.

It would be a lot of effort for a 'one off' for sure. But i may still do it.

I let Pete know it will be some time and we will talk.

There would be more to discuss at this point regarding the optimal tube ID and so on.

Not trying to discourage you from making your own exhaust as thats just cool - but are you aware that MSDS sells headers for the 16V cars for $600 a set?

If you're building a set yourself for your own use then have at it - but there are a couple of options for exhaust already on the table, and given the production numbers, it may hurt to try and compete with the existing supply. There are a few options already on the table:

Grind out the down-pipe part of your existing iron manifolds to match the 32V gasket size, and just add Y-pipe from Roger (maybe Carl too?)
Porken-style: https://rennlist.com/forums/928-foru...-worth-it.html

S3 manifolds + spacer (1.5" flanged section to extend one side) + Y-pipe (from Roger)

MSDS headers + custom X (or 928motorsports header X - I think Carl is selling it again?)

Someone also posted about their setup using S3 manifolds and a whole new cat-back using 3" - I think Hacker has one, and someone else posted shiny pics recently.

edit: Here's pics of headers with 3" custom: https://rennlist.com/forums/9566079-post2.html

LOL, archer's obviously new round here - Dave Lomas (Ketchmi) makes the one sold by Roger and Carl.. and a few other exhaust options they offer. Since a long time ago..

Thank you Hilton,

I did not think MSDS was still making the headers for our early cars. EDIT: just looked and yes they make em still.

Any issues with using these?-Matt

BTW,

The Ott-Style X pipe Carl offers is beautiful, then again everything he builds is top-shelf.

This would be ideal for my side pipe set up. Will have to contact him when the time comes.

The biggest issue with the MSDS headers is that you can't get the bottom of the bell housing off with them in place.. which makes clutch access a nightmare. Some owners have ditched the MSDS headers in favour of the S3 manifolds due to the access issue.

Other than that they reliably add power, although there is the hidden cost of mating them up with whatever cat-back you have on the car.

The x-pipe carl offers is the same one Roger offers - I suspect Roger's price will be better I recommend you phone Roger to discuss what options he has available.

The Fixer

Yes I recall the clutch access issue. That will not work for me as i clean and lube in there once a season.

I am already fabricating a temporary side draft exhaust with what i have in the shop. I am going from my Y to a 2.75" pipe to a Y collector and dual 2" exhaust pipes which exit before the rears. Cost me $50.

But once the motor work is done i'd like to do something better with the exhaust.

Thanks Hilton, -Matt

My experience with OBX has actually been pretty good. When I was more into the turbo Nissan crowd I picked up an OBX 3" stainless catback for a turbo 240SX project. I was really surprised at how clean the welds were and how well it fit and the overall quality. It was basically a copy of an Apexi N1 system IIRC which was a big supplier back in the heyday of import tuning. That exhaust stayed on the car at least 4 years until I lost track of it two owners later, but no quality issues.

They also made a very nice stainless top mount manifold for the turbo 240 guys. A lot of people using high-dollar parts by HKS and Greddy generally looked at OBX as cheap Chinese knock-off crap (and maybe it is) but for those of us that were building turbo cars on a budget back in early 2000s they made some decent stuff.

For me personally my only issue would be serviceability since they are a copy of MSDS not being able to access the bell housing would be a drawback. Knowing Mark is selling used S3 manifolds at $200 is pretty nice. At that price, I will probably pick up a set very soon.

I have used OBX many times. Never ha a quality issue. I'm using their V-bands now. MSDS blocking the bell housing does suck. But how offer so u go in there? lol.

Mark Anderson

I just changed the price so you can order them online if you prefer.

If you are running MSDS and need to access the clutch how far do you need to disassemble? Do they have to come off or can you loosen them?

You can just loosen them up and swing them out of the way. I've had them on the car for about 4 years and haven't had a need to go cleaning my clutch.

The OBX stuff is hit or miss. If it's high volume it will probably fit. A buddy just picked up a set of their headers for this Nissan Altima. They were not even close to fitting and were contacting the starter by more than an inch. It's just a gamble.

Hold On

Who the f**k is this guy !?

I don't clean the clutch with soap and water, I blow the dust build up out (wearing a respirator) as per the WSM, lube the guild tube and the other points, I also lube the T.O. Bearing with WURTH high pressure bearing grease spray.

Makes a difference in clutch feel and shifting for sure and my guide tube and T.O. Bearing will last for a long, long time.

My car was very hard to shift when i bought it.
