Doug Thorley Tri Y's For the Absolute WIN!!!
We carry a full line of Long Tubes from 4 different manufactures and when it comes down to it, I bet we sell the DT 1 3/4" Tri Y's 5:1 on any of my other 1 7/8"'s.
I've posted this before but it's hard to deny it when it's not from my shop, Doug Thorleys, or even someone who deals them.
Food for thought and smart money for sure.....
