nickel platted tip. The single is 3" manderal bent
409 2 into in with one out.
The dual is a
two into one muffler with two out and 2 1/2 409 tubing. Nothing on the JBA system is
304 stainless it is all
409.
There is a big difference between
304 and
409.

If you want to try something interesting, take a magnet at see if it will stick to a system that is made out of
409, (magnaflow, flow master, JBA,) it will. There is so much steal and impurities that it will stick.
Then try it with a system made out of
304, the only one to date that is
304 is (ZOOMERS) it will not stick.
409 has a high impurity, steal count it WILL RUST very fast. 304 will not, it is more expensive yes. Does it look better, yes. Will it last a lot longer yes.
There is no comparison between
304 and
409. And a two into one muffler back to two pipes is not a true dual exhaust, you have two tail pipes but one muffler.
In a single system a Y pipe is used to help eliminate DRONE, and create a scavenging effect to balance out both exhaust manifolds and increase HP and torque. This is basic exhaust engineering, do not let somebody tell you something else. If they are not using one it is because of the cost factor.
