For me it was purely cost. Cargraphic (the new version of sport headers) are nice in that you can remove the cats and add an optional (more money) piece to make it race header for track or more volume. But soul is less expensive AND they warranty the cats. Fitment is supposedly decent etc. So I decided to give them a try. Materials, Cats etc are pretty much the same across brands. Except Dundon who I think uses different steel but doesn’t have long tube street headers with cats (yet). We’ll see I am set to install it Saturday the 23 in two weeks with a friend once the soul header arrive. I’ll definitely be writing a review as well as hopefully getting some video clips up.

Just to follow up I bought Soul sport cat headers. Just installed yesterday and did an epic 4+ hour back road drive this am. I’ll be writing a full review soon but two thumbs up for me. Amazing sound and tone. Definitely DEFINITELY louder. Right on cusp for me actually but perfect and what I wanted. Probably faster too tho hard to judge by butt dyno.
