im thinking about droping some cash on these items on my 02 4.6 my question is will i feel any noticable difference. i have a magna flow cat back system, CAI, larger bbk TB and predator programmer.I am really getting started into the performance side of things now (which was always at the bottom of my list) but dont want to waste the mone on somthing that i will not notice.

 

Longtube headers with a custom tune. Youll gain about 30 hp/35 tq. Shorties wont do much at all and are not worth the money unless you cant run LTs due to smog (Cali)

 

so a set of long tubes and deleting 2 of the 4 cats (using maggies for the 2 highflows remaining) how will that effect the sound? im running a 18" maggie now3"in dual 2.5" out 4" tips. Any suggestions for good long tube without spending a fortune? (dont want to spend 800 bucks on headers and cats)

 

It will be loud. I would go OBX. $500 for their kit.
