Thanks guys. Apparently it goes into a 2.25" catback lol so its not full but close.. Yea I am over my 1 to 1 ratio (422 out of 414) and that was much better efficiency than my 302 with trick flow heads (290). So I am real happy. Again, does she have more? Yep. I could go spyder, afr 225, bigger cam and I bet geat right close to 500rwhp but....enough is enough. I reached my goal, I've got incredible low end and it #$%^ing takes off.
