Just FYI - apparently I made a HUGE low end gain from 2500rpm up with LT's.

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. :)

mine is 3" through the x-pipe and into the mufflers. the mufflers are 3" in and 2 1/2" out. it stays 2 1/2" the rest of the way.

does it drone at all? i have some drone, but it isn't too bad
