Worked on the GT-37 Today (Pics and Video)
Just installed Pypes exhaust my son and I purchased from PY today (Christmas Day). We got the Street Pro all stainless steel system including stainless steel 1" Pypes band clamps. Wow does it sound good with the small Melling cam ( same as the Summit 2801 cam) in the stock 1975 low compression 400.Glad the weather was ok and warm enough to work on the GT-37 onChristmas Day.
 Here are some pictures of the install and a video of what it sounds like.        Click on this picture for a video of the Pypes Street Pro Exhaust

Very nice! What size is that 2 1/2"? What mufflers did you choose? Need a system for my 70. Sounds nice! Was it easy to install? Did everything fit well? Thanks

Looks great. I have the same system on my 69 GTO and love the way it sounds. I am putting the same system on my 72 LeMans but with Race Pro mufflers. Cant wait to install it. Agian looks and sounds great. Its hard to keep the foot out of the throttle with that sound.

I have not actually driven the car yet but can't wait to burn those old 14s off my Rally II wheels.

it fits right up to your factory manifolds? id like a system like that on my wagon, but probably not a direct fit...because of fuel tank placement...

Nice installation! Comparing to the video you posted a few threads ago before you put on the new exhaust, it seems the car is a little quieter than before. At least the exhaust rumble is now routed to the rear of the car.

The classic "coffee can full of rocks" muscle car sound. Very impressive! Stainless steel pipes will last 4ever but they are loud! Good set of full size mufflers on there...lOoks like a high quality system.

put the same exhaust on my GT-37, except I went with Race Pro mufflers. Well, and I also have the two stud flange headpipes vs your three as I have log mani's. Sounds REAL good crossing the traps at 112+!!! :-)))) I found it a bit of a PITA to put on though.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
