Cat delete
So I am on e85 and decided I want to delete my secondary cats. Will I have to retune it? How much HP should I expect to gain? Also thinking if I should just wait and get long tubes.

Do you have the primary cats still? If yes, then removing the secondaries will do nothing but make it a little louder.
If you dont have the primaries (and were tuned like that) and removed the secondaries it will get a lot louder.

Only way I see a secondary delete helping power wise is if you had removed the primaries already. If not I think you are doing nothing but adding some noise.
