Getting the materials all ordered for production megaphone, slashed megaphone, 4" straight and 4" slash cut.
Will get lead times to everyone once it's all ordered. Doing the tips in 321SS, and getting some Ti in to experiment with... Once we have the design I can get the CF molds set and ordered as well!

Working on the 4" straight and slash cut on Monday. To make these look right and work how we want them to (complete interchangeability) we're having to engineer some solutions...
Here's some pic's of the slashed a few depths...
Dundon Slashed Megaphone tips, Positioned In

And a bit more protruding

They'll fit 997's as well!

Nice! Always great to see a Dundon equipped GT3 hang with a TurboS.
Need to get you a stock RS to run against out there! Also you guys need to get vbox's and do 100-200km runs, data would be more consistent vs the drag racing. It is more fun to beat your buddy off the line though!

Race Header Production Updates and Modular Tip Production Update
Thank you for all the orders for Race headers, we're restocking on bends and finishing the GT4 header group buy. We're bringing in some more help to keep up with demand. Thank you all for your support and patience as we get the next batch together.
The first batch of tips should be here before the end of the month as well! Won't be long!

Thank you all for the 991 Race Header orders! We are pushing to get systems on the shelf and ship the 10 systems that are outstanding.
Also good news for those waiting on the modular tips. We should have all in stock, PVD Black and Flame Treated Ti next week! I'll have a separate post up for that.
Thank you for the continued support and Happy New Year!

Three Wheelin'
Is there a purpose for the valved portion of the race headers? Can the valve be eliminated or can it be purchased with valveless side pipes? I am contemplating cutting the side pipe where the red line is after the 02 sensors to fit a different exhaust that only has a one pipe opening. Thanks
