Hello guys.
I was wondering if someone here that have the SGM longtube headers could
help me.
Im going to put a VQ35DE in a Toyota Starlet (RWD) and I have to make
custom headers because of limited space. I want to try to copy the SGM headers as much as possible in dimensions and length and I was hoping someone could give a hand with this.
From what I have found the step of the tubes are: Primary 1 3/4", secondary
1 7/8" and collector is 2" to 2.5". My problem is what are the length on the primary and secondary tubes???
Can someone here that have the SGM headers measure this and send me a PM or write here??

Thanks
Stian
