P body exhaust system on NY?

[ShadowFromHell]

Years ago I had a 3" crush bent exhaust built for my shadow. It was done by a guy who is very talented, it fits perfect. No moving the gas tank or even hammering the flange. Never rubbed. Its currently bolted to my CSX. Id like to put it on my 87 NY. Will it fit okay? I know I need to lengthen it some, but what about the rear section? I believe NYs have a bigger tank the most K based cars so thats why I am concerned. It currently doesnt have a muffler but I'm going to add a race bullet at the back. I dont mind modding it slightly but hate to really cut it up since it fits my Pbodys so well.

They are all close enough that you can cut right after the 2nd 90 and just rotate/angle a tiny bit and get it to fit. I have a shaodw 3" exhaust on my dynasty and a new yorker 3" exhaust on my lancer, etc.
