Maybe someone has the article and can.
Found the pic. These trumpets are installed per the assembly manual drawing, and the way Pontiac intended the trumpets to look. Tips are angled down and outward. Getting them to look this way takes ALOT of time.

I like what Squidtone did with his but the factory look has a slight George Barris feel to me. I feel the same about the 68/69 tips.

Wow, to each their own I guess. These look terrible to me.

Can't imagine those lasting very long going in and out of some of the parking lots.

Ruins the whole lines of the car.

Just go to any GTO show and you will see well over half the cars with the extensions have them incorrectly installed/positioned.

No offense but IMO those extensions aren't placed per the factory spec, they're turned down too far and appear angled out to the sides.



The Blue '66 in my first post is set up nice, again IMHO.
What makes them look out of place is the '70's high jack stance.

Default For 67

Jeff, you're absolutely correct for 66, I do not have a 66 assembly manual. The shot you have off the 66 on the assembly line and the installation drawing prove you're right. But for 67, the assembly manual shows them angled outward. My bad for not doing the research and just showing the pic of the 66 I believed correct.

I still like the way they look on my 67...

Kenth, strange but that car appears to have a blacked out tail panel.. Illusion???? Trumpet style exhaust tips look good on that one for a change..

I'm fairly certain that's the convertible clay mockup in silver, note
the license plate frame. I'm leaning towards GM's artists worked
their airbrush magic and added those extensions to pitch the new
extensions

I have to admit I never really took full notice of the change in '67.
Clearly not the same. I just wish these drawings gave more precise details.

I believe they were angled outward for sure on 4 spds without the resontator for 67 (2 1/4" tailpipe) but for 67 autos that had the 2" resonator, probably just like 66 (angled straight down like in your pics)
All depended on what factory tailpipes they had.
