]Hi Slowy, I Have block hugger manifolds on my 302 with straight through cats 2 1/4"and 4 hotdogs ( 2 each side 6" long) Mufflers wont fit.
The sound is very disappointing compared to my ute which has 2 hotdogs 12" long. i think there is just not enough length in the pipes to get a nice note out of it. sounds a bit like a V8 speed boat. not sure if the link will work
