Anyone running a tri-y header out there?
Sounds like a logical choice for what they claim. If you have run headers before did you notice a difference using the tri-y design?

 

i have not used them. but in late 60s i saw a full size 67 Pontiac that ran them. they had a different sound. the other thing he ran the engine close to stock specs. the bearings and so. and did very good. i think try-y is to make mid power better. i think for street they would be good. also i think they are harder to make.
