i am about to put in my new engnbldr 261 cam and was wondering what i should do exhaust wise. I was thinking of taking out the cat but im not sure if i should do that because i might lose backpressure. I already have an LCE header and a new muffler so should i get rid of the cat or not... I was also wondering if i should do any mods to my intake since i am putting this cam in?

You can put a new cat in, 2-1/4" should be good. Don't remove it.
