Re: 69 yenko chevelle
Joe, only the chambered exhaust got the resonators in 69. Without them the system was very loud! I have owned and worked on numerous unrestored 69 Chevelles and the majority have the "angle cut" tips and not the rolled tips as seen on a couple of restored cars. The rolled tips have been found only on a few original cars and I am thinking only out of one plant. I have been researching this for a long time and I am curious to see the tips on Chads car also................RatPack....................... .......

Re: 69 yenko chevelle
From what I read on the rolled edge exhaust tips, they were used in early production and got a lot of complaints because the water from condensation would collect in the rolled tip. The water would then sit on the base of the exhaust tip and rust. One original owner said he had his replaced under warrantee and got the cut off ones as replacements.

Re: 69 yenko chevelle
I owned a couple of low mileage L78 ('69) Chevelles a few years ago and they both had the "cut" tips...both of these cars were Baltimore built cars..

Re: 69 yenko chevelle
I had a '68 Chevelle and bought a set of the exhaust tips after the '69's came out. Had to modify the tailpipes to make them work but the ones I received from GM had the rolled edge. Evidently the rolled edge pieces were early service items. They barely lasted a year before rusting through at the bottom. The next set I got were the straight cut. My guess is GM cured the rust problem by switching to the "new" design.
Can't testify to the use of resonator pipes being exclusive to the chambered systems in '69 but my '70 came with resonator pipes and straight cut tips, as did all '70 SS Chevelles (excluding ElCaminos). P.S. When I first met Rick Nelson, I said the same thing "I thought you died in a plane crash." His response was "I did, but I got better." Super guy! Very knowledgeable and talented.

Re: 69 yenko chevelle
Belair62, Baltimore, very early, before COPO production ever started. That is why I am curious to see what Chads car has. I have owned three unrestored 69 SS Chevelles from the Baltimore plant and all of them had the slant cut tips and production ranged from 09?-07?. I am thinking that there were possibly only a handful of the rolled tips ever produced. I don't have my notes handy about the exact production date but I am almost positive that the two or three cars found with them originally were all late August 68 build cars. There was a BY Yenko Chevelle that was restored that had the rolled tips and I don't know if it actually had them on there originally. I think the owner had one tip and used it as a copy to make the set for the car. I have only seen one original set personally and a restorer friend of mine has seen another car built the same week in Baltimore. Wish there were more original cars out there to compare..............RatPack......................

Re: 69 yenko chevelle
That B. Y. Yenko Chevelle appeared in a magazine with the rolled tips and they said they were original. I believe it is an early Yenko with 03A build but I am not sure if rolled tips were really on it new. I was told the owner of the car or the guy who restored it was or is the one selling the repro rolled tips.

Re: 69 yenko chevelle
Joe, I had seen that car at a show and I guess it was the owner that was telling me that he only had one tip as the other one was gone when he bought the car. I would assume that they were on the car new but the picture BKH has showing the Yenkos with the slant cut tips would lead me to believe otherwise. One thing that could be possible is that a secondary source was used and they made the slant cut tips and were more readily available.? [img]/ubbthreads/images/icons/confused.gif[/img] One thing is for sure, with the rolled tips you do not have to worry about cut knuckles while polishing the bumper!...............RatPack..................... ......

Re: 69 yenko chevelle
Can any of you guys who have seen the Original rolled Ex.tips,tesify to the fact that the Part number was indeed stamped into them?
If so,was it on the top or bottom of the Ex.tip?
