xforce headers stepped or not?

[Craig93]

Hey guys, i have a ve ss sedan and want to no which headers would be best the stepped 1 5/8 > 1 3/4 or just the 1 3/4? Is there much difference in sound? thanks

No differance in sound as the 1 5/8 part is only the first 4-6 inches of each pipe. Stepped headers apparently give better mid range torque, but the 1 3/4 are better for top end power.

The 1 5/8 headers will start being a restriction as you approach 300rwKw - up until then, there's no issue.

ok great. sounds wise any difference?
I have the stepped at the moment with 2.5" xforce and was wondering if it was a bad move. I am yet to hear a 3" with the stepped headers but i dont want drone.
The 2.5" does sound alot better outside of the car i must say the sound inside makes u think its really quiet.

3" exhaust is a hell of alot louder than 2.5", depending what brand you get will change the rear boxes which will give you drone.
I have 1 7/8 to 1 3/4 headers into full 3" system with varex mufflers and it is crazy loud when i'm up it, but cruising on 110-120 no drone.
