I picked up a t-top car and it has the hooker shortie headers with what I believe is the Hooker Blackheart 3" exhaust system on it. (2 into 1 then back to 2 at the rear). I doesn't have subframe connectors yet but it appears the exhaust would interfere with most brands. Anyone know what will/won't work or get rid of the system and run true duals? Thanks!

I think you are referring to a standard Hooker exhaust system...the only Hooker Blackheart exhaust system available for 3rd or 4th gen F-bodies is the 2.5" true dual systems.

Yes,I must have been mistaken. It's a 3" system. Has the shorty headers with a y pipe into a single exhaust bach to the muffler then dual 3" out of that.

Hooker Aerochamber single 3" kit most likely. I swear they had a Blackheart or something similar sounding for a system.

They didn't. I've developed every single Hooker Blackheart exhaust system for 3rd and 4th gen F-bodies that has been released under the Hooker Blackheart business unit. It is possible that Summit incorrectly associated a Hooker Blackheart logo with a standard Hooker exhaust system, but no such system was ever developed by Holley.
