Hi folks, hope everyone is doing well. Finally had some time to start assembling another project and am dealing with a mismatch in parts.

Have Sierra Madre headers and what I thought was a 1974 exhaust.

Basically the headers are too long, or the flanges on the exhaust are too tall (far extended) from the rest of the muffler.

Any ideas?

Thanks!

You’ve got 1.7/1.8 liter type headers and a 2.0 liter type muffler. As you’ve discovered, they won’t line up.
Either configuration will work on your car, but you can’t mix the two. Looks like Sierra Nadre doesn’t differentiate between the two styles when ordering. I’d contact them to see what’s up as their web site is misleading by stating that the headers will fit all 70-76 cars. They will, but only if you have the correct muffler to match.

Thank you!

I will contact them, pretty frustrating.

You have 1.7, 1.8. 2.0 ARE FLAT

Thanks - sent Sierra Madre a very specific email and referenced this information.

Thanks folks.

When you get your correct muffler, check for excessive weld drop thru closing off some of the ID at those flanges. I'd obtained an old OEM 1.7 muffler with big drop thru and ground out this drop thru to get ID to the pipe size.

Last I looked Sierra Madre does not offer their headers in the 2.0 configuration. Which is SUPER ANNOYING. I do not understand the decision to stock less popular and desirable headers for the 914.

The picture of the headers on the SMC site clearly require 1.7/1.8 version mufflers. Expensive too. I would not waste the time sending and waiting for emails. I would call SMC directly.

An oops for certain. I've ordered tons of stuff from SMC and would imagine they'd make this right.

Thanks gentlemen.

I spoke to them live this morning and sent them some of the documentation from this thread. The person I spoke with was very cooperative, and they are looking into it.

I also found other errors on the site that I have made them aware of.

Appreciate all the responses.

Quick update;

Sierra Madre website still listing wrong parts compatibility in multiple places

Alternative part that shows available to fix their error is actually 6-8 weeks away from being available.

I understand that running a vintage car business isn't the easiest thing to do, but you'd think they would care enough to prevent other people having the same issue.

Frustrating.

Totally frustrating especially since info on a web page is so easy to correct. I just ordered some stock torsion bars from them. Hopefully, what I actually get are the stock size bars.
I paid a bit more ordering through them because they had them on the shelf. Even Sway-Away didn’t have them in stock.

If you need them quickly you may want to give them a call to see if they actually have them because the customer service person just told me they list everything as available. That only means they could order it for potentially months away in delivery.

When it shows available on the website, they use a several day formula to show that you could have it between two and five days from now even if it isn’t something they actually have in stock

Hi folks - wanted to follow up to close this out.

Sierra Madre made this right. They took the incorrect ones back and gave me the sale price on the correct ones. Took three weeks but they showed up in good order and everything fits properly.

Appreciate everyone’s help on this and wanted to publicly state that Sierra Madre stood by their product / customer.

Thanks!

Good to hear!
Aldo happy to say that the new torsion bars I ordered from them were correct and matched the stock measurements.

Posted by: VaccaRabite Apr 22 2024, 06:30 AM

Does this mean that Sierra Madres actually has the correct 2.0 heat exchangers/headers now? Not just the 1.7 crap they have been peddling for the past 3 years?

Wow appears they have got their act together ?,my dealing with them were 90% difficult and products were sub standard or simply didn't fit , I agree with the comments about stock on the website as often not in stock or is incorrect in description.
Perhaps they should look @ at a better business model as member vendors on here follow...food for thought as they say , I have been 100% happy with them.
Rant over ,cheers.
