The “Other manufacturers” may not route the tubes in the same manor and are more of a “race” header over the street strip TTI’s. And they cost a good bit more.Ouch ! Kept putting it off but finally had to pull the trigger.
1 7/8 W2 Race headers with 3.5 collectors.
TTI is one of the only games in town for W2s. Sure hope they fit well.
I bought then raw and sprayed'em with a can of black header paint. Used a zillion vinyl gloves to keep then clean.I actually wanted black but it cost another 100$ and I was already sweating.
