Updates

There seems to be some of the same questions that pop up when people go to install these.
1st is what type of nuts should be used for installation? You should use the same setup as a 911 with barrel nuts in the locations with the pass through holes. The attached photo shows what they are.

Next what oil lines should you use? Typically stock setup is very efficient but a stock -6 cooler has a bracket that can interfere with the heat exchanger so note that. Eric from Pmb is the only one to my knowledge that has run into this but should be noted.

Price wise currently they are $1950 for 914world folks. I can hold that price for sure for the next 4 sets but after my current stainless inventory is used up then we will be affected by the current steel price surge.. This is for both for 1.5" and 1.625 ..

Have plenty of parts to make a system for any and all. Anyone need either headers or heat exchangers?

Posted by: mb911 Aug 26 2018, 03:26 PM

Public notice. After doing time studys on these there just are not worth making. I will sell the last 5 sets at the quoted prices but retail will be going up to 2800.

Just did a 275 mile tour in PNW fall weather ( that would be cold for my Alabama wife) and we were toasty warm thanks to Ben’s HE set. I’m going to be able to plan some winter drives now.

Thanks

Hi Ben,

What's your price increase on a set of just ss headers in 1 1/2'' and 1 5/8'' both with a 02 sensor fitting installed ?

Posted by: mb911 Oct 15 2018, 06:38 AM

Price will be 2700. I will still have a discount for world members.. I am holding pricing until Jan 1 at 1950

Posted by: mb911 Oct 15 2018, 06:39 AM

Oops just headers they are 1200

Posted by: mb911 Dec 3 2018, 02:45 PM

Last chance to get a deal on these .. New price is confirmed at $2700 starting Jan 1 2019.

Posted by: mb911 Dec 30 2018, 05:05 PM

Tomorrow is the last day for this awesome deal..

Posted by: Luke M Apr 25 2019, 01:34 PM

Here's some of Ben's work of art. These things are sweet and weigh a heck of a lot less then the factory parts. All in stainless steel which is another great benefit.
Can't wait to get my 6 done it's gonna sound great I'm sure of it.

Thanks again Ben...

I have Ben's large tube, 1.62", heat exchangers and the quiet 2 in 1 out muffler on my 3.2 and all I can say is everyone who looks under my car is blown away by the heat exchangers and muffler. I love them and could not be happier. The heat is as good as if not better than the stock heat exchangers. A top quality product produced by one of our own members.

Posted by: Cairo94507 Dec 30 2020, 10:22 AM

OK, I could not resist Ben's work so I also bought one of his little bit louder mufflers for my car and just swapped it on. It is a little bit louder in all the right ways. When it is sitting and idling, it is glorious. Then when you get on it and the RPM's begin to climb, it really sounds great. Overall, I love it. Easy to swap back and forth too. I did not have to remove the valance. Just undo both of the muffler bands and then the 4 bolts and off it comes. Ben's work is just top level craftsmanship.

Luke or Ben, do you happen to have weight comparisons (whether imperfect or perfect)?

I've come around to adding heat, and this is the way I am going to go when the time comes. Now Michael has me thinking about Ben's muffler too...

Posted by: mb911 Jan 14 2021, 10:04 AM

So roughly the boxed shipping weights are the same for heat exchangers oem or mine@40lbs. Headers are about 10 lbs lighter boxed for shipping.. I never did just weight them without packaging.

Also note these are in process of changing. They will be lighter and use an f1 merge collector and the driver side and passenger side will be mirrored and will no longer look 90% oem but rather mirrored driver side. This will save bends, time, costs, weight, and improve power. And still look fantastic. They will look very oem to the driver side. The passenger side had 15 more bends in it then the driverside and is just an incredible amount of time and money including waste for a none essential feature(I argue it to not being a feature)

Well unfortunately with stainless prices I need to raise retail to 3495. Contact me if seriously considering buying a set as prices are up and down and maybe able to cut you a break.

Posted by: mb911 Jan 7 2022, 09:47 AM

These are special order only now and based off current market pricing.
