ok this mite be an annoying q, but how much power do you all think i would gain from...

longtube headers.
cat back true dual exhaust no cats/resonator stock mufflers
4" air intake (tb to airbox) then removed silencer so 4" from bottom of air box to ram air scoop under car.
and a ported intake

all on a 95'

The 4" intake is waaaaay to much for a Mark VIII and completely unnecessary.

probably 15-25 horse. 25HP for sure with LMS MAF kit.

I haven't been in the modular game for long but I'd think you'd gain 15-25 from headers & exhaust alone. Then again I doubt the other mods would do much (depending on what exactly you mean by ported intake.)

I gained possibly 15 HP from 3/4 length headers, longtubes should be about 20 HP. You can get 5-10 HP on the intake side. Most will say 10-15 HP gains on the exhaust over stock.

Aggregately, you could see 25-30 HP, tops.

to be honest i only went with 4 in tubing because the 2 holes in the airbox are 4" meaning the top, with the mass air, and the bottom, where the silencer was.
