Well hello guys im still new to the hole thing really but my exhaust system is stock all the way through except my muffler which i took off and put a glasspack on an brought my tip out in front of the tire i have a 1997 f150 xlt has a little rust issue on driver side not my problem at the moment tho i have a leak from the driver side manifold will short tube headers fit right in place of those or will i have to do some mods to the y-pipe and my cats

 

BBK Cold air intake
80mm BBK throttle body
JBA shorty headers
JBA 3" dual exhaust

I did the cold air first and wasn't impressed with the increase in power so I added the larger throttle body and was still a little disappointed. Finally I added the headers and exhaust which seemed to make the difference. I am pretty pleased with them all now!
