I think Beedub considered cutting off his ears when he was running 100 cell cats with his RPI rear boxes...wspohn wrote: ↑Sat Jun 20, 2020 9:55 pm Can anyone comment on a CAT delete pipe for the secondary (rear) CAT in terms of both source/price and effect on sound? Already have RPI rear boxes but was pondering whether the deletion of the CAT would make the car objectionably loud. Not interested in deleting the resonator in the middle of the system for that reason.
