summit still shows long tube headers for all gm models, 95 camaro . Summit, hooker, procomp, hedman etc.
At least here in Texas.
I have seen literally no changes in parts made/sold due to epa vs rpm act etc.
many are in stock, which is a big shock, others are on back order till may, march etc- as is normal these days.
Parts supplies are going to get tighter /longer wait times for at least the next 12- 18 months just due to supply chain difficulties in bulk raw materials.
fwiw- hope it helps.
Might want to try looking at texas summit stores- again, we havre not been told even once that later model parts are not available due to epa and we are back up close to 80k a year on parts purchases , about a third of those are 80's-90's and newer, well, maybe a third, have not really run the numbers by years of manufacture .
The point is- we arent seeing those issues here - has not affected us. Just purchased intake, carb, headers etc for a 78 Ford fore customer car- again, no issues.
95 camaro, headers, intake, carb, cam , rockers, shifter etc, etc- no issues.
Perhaps this will be of some help to someone.
Blessings all.
