price doesn’t seem bad… i wanna know how it works, how it sounds?

i would also like to know…i really want this kit

if psi and cfm is the same would a 2 horn or 4 horn be louder??

the 4 horn will sound more like a train.

Ive ran the 4 horn with just 2 before. It didnt sound bad. I ran it with just the 2 largest horns, not this exact combo but yea.
