Hey guys. I know this topic has been beat in the ground, but has anyone changed from a 14" body to an 18" body because it was too loud? I'm tryign to decide which magnaflow I want and it's coming down to the 5x8x14 or the 5x8x18. Any input would be helpful!
well, if you go by volume, the 5x8x18 (not taking into consideration the volume of the tube on the inside of the muffler) would have approximately 720 cubic inches and the 4x9x18 would have approximately 648 cu inches. The more cu inches inside usually means the more "muffling" you'll get. Since I have custom pipe, mine's gonna be c/c
