Shocker XL's

If you install a second set of shockers (The XL’s) along with the older shockers, will it be that much louder?

yes it will especially if you use the 1/2 airline and 1/2 valve.

Is there an upgrade program here? I would like to get a set of Shocker XL’s

the shockers are still the same no matter what… The (XL) upgrade is the 1/2" valve and 1/2" airline http://www.hornblasters.com/products/details.php?i=shocker-4-1-2-in-valve-upgrade-kit here is the upgrade kit…

the way i ran mine was the 1/2" line from the tank to the 1/2" valve to a 8 way manifold made with two of the shocker manifolds then to the horns…

Oh, well thats kind of a waste for me as I’m already running 1/2" air line with an SMC 1/2" valve already, and I’ve upgraded the 5/16" connectors on the horns to 3/8" connectors.

So now my question would be… will it still be louder although I’m already running the 1/2" airline if I add another set of shockers?

yeah then all u need to do is like i did and add the extra horns… the lines from the manifoldto the horns on mine were the stock size line…

hell yeah it is loud… i had 8 horns just like “seven” with 1/2 air line and 1/2 valve at 200psi and damn it was loud now i have a k3 just a lil louder

i have a old set of shocker horns and the new xl shockers and its fricken loud! im planning on getting 2 more sets of the xl’s
