New equal length headers

[Larry_Ratcliff]

Thanks! this is why I would love to have your heat exchangers with the B&B I would have to dump my center exit 2 out muffler to their side exit single out and have to redo the rear bumper:



Let me know when they are close I suspect I can sell my SSI's and cover most of the purchase price.

Very interested in a heat exchanger version for a 2.7. And yes, I'd pay a little more for "Made in the USA". Outstanding work!

Love this car. More pics please... (front)

There is much data supporting the need for larger ID primaries on engines displacing 3.2L or more. This is the reason we offer 1.625" and 1.75" versions.
Yes this system is designed to work with early stock muffler components. It is not good to have your options limited by the use of a specific muffler or related component. That is part of the pricing consideration. You can save a bunch of money if you already have an M&K or early style stock inlet muffler. If not our host carries them.

Are you planning on dyno testing these units against others?
Evidence of performance gains would be a good selling point.

Looks like the potential for a very good product. Just don't take anybody's money until they're ready to ship............ Sorry, that was a shameless dig for those who've suffered through the ongoing 17" Fuchs episode.

Ouch.............

I'm anxiously awaiting to see the heat exchanger setup. Since these headers can use a standard early style muffler buying a set would make the exhaust portion of my 3.6 project go alot easier!

I gotta have heat!

The length of the primaries is critical to where the power band is in the rpm range. With shorter primaries the power band will be at higher rpms than with longer primaries. Will there be dyno tests run on these with comparative results posted?

[RarlyL8]

No, I have not taken any deposits. These headers are in production now. Contact me to get in the next run.
Yes dyno testing will be done on the various sizes. It is impractical, if not impossible, to test against every known manufacturer and every engine combo so we will use engines with the proper displacement for each size.

What size primaries should be used on a stock '95 3.6 engine in a primarily street driven 911?

stock 993 headers/HE are 1 3/8th ID so the 1.5 inch header should be perfect for street . though you could bump up to 1.625 for maybe just touch better all around performance

[RarlyL8]

I have a local guy using stock 993 exchangers on his race car who may do some dyno testing with our system. It will be good to see the difference these headers make vs 993 exchangers. The design of course is completely different as the 993 exchangers are short un-equal length tubes with a smaller ID. I would expect a significant increase over stock by allowing the engine to breath better with an equal length system.

[RarlyL8]

I have been asked many times about installation. Being a DIY guy, installation ease was high on the priority list. These headers can be installed in minutes using no more than a ratchet wrench and extension. All nuts are easily accessible and the gasket protectors make installation a breeze.

It's the removal of the rusted on monsters that are the nightmare...

Yes the available tubing sizes will be 1.5", 1.625", and 1.75".

Pricing will be $1650 for the 1.5" in 321. We will offer optional T304 stainless for $1450.

What is the introductory pricing for the 1.625" headers in 321 and T304?

Thanks!

Don't forget the 993 heads have threaded holes for both 993 exhaust flanges and 911 exhaust flanges.

I'm thinking about ordering up a set of 1.625" headers with 911 flanges. Then if I decide to use them on a 993 engine I'll just swap the 993 exhaust studs over to the other holes. If I don't go with the 993 engine I'll use the headers on my 3.2 engine.

Just another option...

[RarlyL8]

T304 will be offered later as it is thicker wall and heavier to compete with the quality of 321. The 1 5/8" primary version will run ~$125 more than 1.5". Introductory pricing will be extended throughout the first production run of each size.

Excellent work!!! I will be considering the completed units with heat exchangers when they are ready as well.

Any new news????
