I read your ad...
Was on my '90 Grand Prix Turbo and worked fine. Was only removed because I came accross a NOS factory one.

Really, that one would have lasted waaaay longer. If your really just sticking an OEM one back on its gonna be garbage in no time. There were reports of people cracking these things in like 10-20k back in "the day"

That flex on the left looks like the ones jeff used to use on his pipes.
