I am thinkin Gibson ..Hows Magnaflows lowend. I saw their dyno charts but none for gibson... Im thinkin Gibson DOR and their headers. I just want lowend gains so I have advantages on the street. Also any shift kits or anything out there yet?

 

I've got a magnaflow cat back system and i'd say the lowend is pretty good, sound good too! i don't think an exhaust system will give you what you need 4.11 gears would do the trick!!

 

There are quite a few guys on DT who have installed shift kits.

 

I don't think either one is gonna hurt ya. What about a tuner?

 

Well..I read 4.11s arent much different than 3.92s I have. I was thinking 4.56s but I dont wanna have highway rpms at 3000... I have plans on tuner,CAI,and all that jaz...I wanna drop the clutch fan and get an electric fan too.... Talked to my local tranny/rearend shop and he can do me the 4.56s for around 2000,including the Superchips Cortex tuner. He said he didnt think they had shift kits for the 2008 but he could do me a better torque converter. Anybody have experiences or suggestions on a new torque converter?

 

The word is only a 300rpm increase @ 70mph with 4.56 vs 3.92. About 2300 @ 70mph.
Magnaflow is better built stuff. They just don't make headers.
There are a couple on here with better torque converters. Truckin151 and dirtyoldjohn have one I believe.
