Totally agree on the straight throughs. Looking to replace the straight through Borla's on my 33 cause they are just too loud. I've been looking at Jones mufflers. Think their #MF1225 is an oval 14" chambered design all stainless unit in a relatively compact package and not too pricey. Just haven't heard ( pardon the pun ) much about them. As always with my 33, I have room constraints.
