Rush crossover exhaust question ?
+++++++++++++++++++++++++++++++++++++++
The diff between them is 1/4 inch...
.That means the 1 3/4 in it the hole in the middle all the way through the baffle.
the 1.5", means it has a 1.5" hole all the way though.
If U have or plan on doing stg1 U'll be better with the 1 3/4''
if U think U'll ever do cam U can even go with the 2''ers..
Quality wise,, I've had my Pipes for 4ys and they still look new when I polish them up.
