Hi guys I was wondering if i could get a little help.... I got a 1998 F150 4.6L 3door 6.5 box and i want to put a good exhaust system on it and possibly headers. I also wanted to put K&N Air intake system 77series i really don't know anything about what is good and what isn't so please help!!! The exhaust i wanted to put on was the borla 14808 cat-back. Any help would be great!

Thanks!!
