what horsepower would i expect from these mods to the wheels
kooks 1 7/8 longtubes with highflow cats
magnaflow exhaust
rotofab intake
and a custom tune
350-360hp?
torque?
just trying to figure out where i should be and what to expect in the next few weeks as my headers are being shipped and installed.
im more interested in the sound then the power as whataver the increase is will be enough for a while.

if anyone has a link to someone with these mods or a thread with these exact mods, please let me know as i have yet to find this exact setup with a video.

Depending on the temp and the tuners ability you should come in at 360-380 HP 355-365TQ

my tuner is very good and the temps in florida suck. but intake temps before stayed around 98.

and darkmanx, just hurry up and order the rotofab and get an exhaust done at my shop. then order headers

what things should i look for when doing the install and be careful on? im going to do it myself to save money. i dont have a lift, but i do have 3 jacks and jackstands and all the tools needed

I have the 1 3/4 Kooks with the H/F cats and kooks axle backs. I also had Roto-fab and custom tune done in June here in Jax and put down 360/360. That was awhile go though.... Good luck!
