Hooker super comp vs TTi 1-3/4 step header

The TTI 1 5/8"-1 3/4" step headers are pretty helpful in a diverse range of applications.

In this mild 360 dyno test, they were better throughout the range.

Several NHRA and IHRA Stock class cars use them, including myself, with very good results running mid 11's down to mid 10's with Stock class spec 340's and 360's in cars between 3,000 and 3,700 lbs! A TTI 3" X-pipe helped also. But I never compared the two header brands myself.

I believe ou812 did some dyno comparisons using the Indy/RHS LAX heads on a 360/410(?) stroker between the TTI's and Hooker (forgot the size), and the TTI's won out.

Do some testing with jets to make sure any change is optimized, including between headers.
