I have an K&N intake on my '87 TII and I am about to put a 3"DP & 3"MP and cat-back. What stock parts should I replace. Will I need a boost controller, BOV, I don't really know. Pretty much all I want to know is if it is safe, just to throw a intake and exhaust like that on a stock engine. Any input would be great thank you. Sorry kind of a newbie and I did do a search, couldn't find ****.

Easy.

Get a fuel pump, and make sure yours is seeing the proper voltage.
Also get a S-AFC, and a fuel cut defenser.
