Halltech

We have a set of takeoff titanium Akrapovic tips (125mm) that we will trade for a set of the carbon fiber 115mm units or the 115mm titanium units.

Halltech is going to make a carbon fiber tip in 115mm and need one of the 115mm units to finish our mold.

Our tips will be CKN (carbon fiber, Kevlar, Nomex III and be the heat resistant carbon fiber.

Anyone?

So glad someone is finally making these tips! I always wondered why no one jumped on the opportunity!! Bravo, good luck! Wish I had some for you

Halltech

We had 4" tips in testing, but they looked odd with too much gap between the tips, which is why we need the AKRA 115mm set or at least one to borrow.

I will check mine when I get home in December. Cant remember what size I have....

Halltech

That would be great. Anyone that can help will get a set at our COST. They are not cheap to make, but they are not going to be outrageously expensive. Under $1000, maybe $800 to $850 per set.

These are our first set, made in 4" which do not look correct due to the spacing. They work great, and save over 5lbs. vs. the AKRAs.







The 115mm (4.53") tips will look much better.

Im interested, sending you a PM

Not sure what size mine are...

Jim,

I assume these will be secured in a different manner than the prototype Halltech carbon fiber tip left at Autobahn a couple of years ago.

My twisted effort at humor. Everyone here, especially me, is aware everything coming from your shop is top notch.

Halltech

Those look like the 115s. Tape measure across the width should be around 4.5 to 4.6". The 125s are 5"

Halltech

The reason those split at the seams was due to the titanium exhaust expansion. The carbon tip was not large enough to accommodate the expansion of the titanium, under all out race conditions. We will have aluminum sleeves or Nomex integrated into the tip attachment, to isolate the exhaust heat.

If this works as planned, our tips are .75lbs for the 4 vs. 6lbs for the titanium tips. What is ironic, is that the mid-pipe in titanium is only 9lbs!

Measured now that I got home, they are 4.875" which is 125mm. Sorry.

djfury05

I will check when I get back home too. . Any incentive for the supplier of the tips lol?

Halltech

A full set at our cost when finished.

djfury05

Gotcha. Guess I should have read every reply . I'll let u know when I get home. What's turnaround time look like getting them back to supplier?

Halltech

I only need one tip for reference. a couple weeks max.

djfury05

Pretty sure mine are the 125mm ones.. OD was around 4.75". ID from beveled lip was around 4.25".

Halltech

We'll look at this again once we get ahold of the 115 tips, if ever.

We already have our set of carbon fiber tips, so this exercise would be 100% for the Akra folks if there was actually a market for them.

Not much response here.

Jim,
Sent you another PM last night if you didn't see it. Love to make a deal if possible

Halltech

We're going to pass right now. The ducts for the fender and NACA are $600 my cost, and the molds are at home, not at our shop.

We'll figure something out.

atljar

Understood. Let me know if you change your plan.
