Some 3" exhaust tips to pop through the CGT surrounds; made these with the assistance from our hydraulic press + the Dome-die tooling.
The small 1⅞" od tubes (when finish welded) will be where the 1¾" od tubes with exhaust gasses will enter the tips. Why so small? See following ...

Our Hydraulic press makes all MSDS header collectors, cones, reducers, specialty dimples and domed caps on tubing ends. The end caps on these 3" od tube sections are 1⅞" id.

The goal was to move exhaust gas from left and right side Garrett turbos, but we have decided to vent the Left + Right wastegate exhaust down to the rear of the 914 instead; and the turbo exhaust out the top of the rear trunk lid...race car (or even 918) style. Routing 1¾" header tube around the drivetrain 'Maze is so much more compact compared to dual 3" dia tubing. Cooler engine bay temps as well, the wastegates oscillate the dispersing of exhaust gas, wherein the turbo exhaust is a constant flow.
Turbo exhaust will be simple 3" dia 45° angle cut, short and compact. Pic shows basic 1¾" mandrel bends which will be prototyped into place once the wastegates are situated.

Closeup...the final length of the tip protruding past the CGT surrounds TBD.

Turbo exhaust on this v8 Indy engine, short and right out of the turbine, and built into the slipstream of the body, very cool design (IMG:style_emoticons/default/biggrin.gif)

In house mfg. od/id swedge tubing (exhaust joints); one side welded in place, and one side snugged down with these SS clamps...available at most hydraulic supply stores.

...and some time spent on tapping into the Daley oil pump for AN#4 oil lines (turbo o/p), and figuring out the large AN#18 route to dry sump tank. Large firewall access makes it a lot easier.

AN#4 oil line (Left side turbo) supply is a snug fit and clears the belts & pulleys.

@Lucky9146 she's looking Sweet !! We threw the Sonauto car in the application...don't think they want a repeat car to show again as it was at San Pedro couple years ago (IMG:style_emoticons/default/blink.gif)
Our '79 VERBOTN was shown at Lüft 2 'Bandito Brothers years ago...but no application put in for #342 at Universal City.
LMK if you need your 'RSVP 'Local' spot this year (IMG:style_emoticons/default/smile.gif)

Simple fabrication today; just tack welding the dual exhaust support bracket that will come off of the trans nose-cone & guide the 2 pipes into the rear bumper. I'll finish weld (presentable!) after test fitment .

Did some innovative 1D mandrel bending in 2.75" od this week and came up with an end that gives a slight kidney bean + slash tip look: close enough for that Porsche Indy exhaust style.
