Made in the USA

Hey go-fish -
I agree with your post 100%. I always do my best to source USA-mfg. parts.
If you're going to buy TTI headers, try to purchase them at either the Spring Fling or Fall Fling events. TTI is always in attendance and usually runs a 'show special' discount.
In your post you mentioned "right here in SoCal"...where in SoCal?

They manufacture them right there in the Inland Empire (Corona).

I called them yesterday and the kind lady said they only take orders at the Flings and process the order when the reps get back to work. They had some theft some years back and quit bringing inventory. The reps that attend the show take headers examples only and drive their own vehicles so they won’t even deliver parts to you at the Fling. They give a 10% discount on orders from the show.
