the 67 Canadian Pontiac service manual should have a drawing - there's one in the 70 book for mine.

Anyone have a scan of that 67 document? I don't have a 67 manual.

My 86 Monte SS had factory tail pipes that you describe as running straight back and exposed for about two feet or more under the fender line. They were stainless even back in 86. I painted them black at one time but then one day I got ou tthe emry cloth and polished them and that was it, they stayed that way ,never rusted looked fine.

Point of all of this is if you invest in the last two feet of stainless you can polish it and they will look good even if it is just that little downturn that is exposed.

I had a Dk Jade green 92 5.0 Lx Mustang Ray that had the cannons that you could see from the side. I used to be really fussy with them, pretty much getting down and going over them with neverdull quite often. They looked awsome and really were a defining feature of that car.

But on the big car I think they distract from that clean line running up from the rear wheel. I can't stand seeing that tail pipe on these big cars. At the risk of upsetting those who have it...I think it looks like the pipe has been mis-installed when it hangs down. More so when you see a big ugly clamp at the end before the turndown. I'll probably eat my words next week, but what I'll be asking for from the shop is;

Remove the heat riser.
Keep the pipes as tight to the floor as possible.
H pipe connector.
Mufflers mirror imaged between left and right.
Mufflers hang even as viewed from the back.
Tailpipes are concealed as much as possible until the turndown.
Nice reveal, good angle, even left to right as viewed from the back.

Not too much to ask?

when I put duals on my cars, I made sure they looked as stock as possible. The 350 cars had the exhaust on the left, whereas the 454 cars had it on the right. Keep in mind the frames are drilled on both sides as they don't know which cars will have duals, etc.

I used the proper frame brackets and proper hangers. The local muffler shop used a tailpipe hanger that was close to the original, bolted in the proper holes. The frame brackets aren't available, as they never wear out, so I used ones scavenged from the junk yards (69 & 70 used the same). I got a new set of hangers for one car (not GM, but through the muffler shop), but that seemed to exhaust (forgive the pun) the supply. So my other cars used scavenged hangers as well. Scavenged pieces were sand blasted, then covered with a light coat of grease so they don't rust.

I took a copy of the page from my manual that shows the proper routing, etc of the exhaust system in with the car to have everything done.
