Question about stock Exaust manifolds... are 01 and 02 stock manifolds the same?
and from what I read these are superior to the 00s and older correct? Almost as good as a shorty header?
Need to know kinda quick

2001s and 2002s are the same. In fact, the 2000s are also the same (flow-wise) over the '01-02s. The only difference is that they have an EGR provision. This won't cost you any power though.
The power advantage of 2000-2002 manifolds over 98s and 99s is around 3-5 rwhp. Shorty headers would be about 5-8 rwhp better than the better 2000-2002 manifolds, so make them about 8-13 rwhp better than the 98-99 manifolds. Understand?

thanks.
thanks.
Some people gain next to nothing going to shorties on an otherwise stock exhaust & motor.
