I bought the black chrome version of these and wasn't happy with them at all as a bolt on. they look like a cheap bolt on especially with the mesh at the back and seeing the original tips partially hanging out the bottom. I grinded the spot welds inside and hammered out the mesh but you could still see the original tips. I then cut out the hose clamps welded inside and took them to a muffler shop and had them cut off the original tips and weld the new tips directly to the muffler. Unfortunately the guy welded them crooked and he couldn't get them back off so he only charged me $40 WOW! how generous! Jackass. Anyway, in retrospect I would have left the hose clamp on and trimmed the original tip short and just tighten the clamp like originally planned just with a shortened factory tip. If you want you can cut a piece of aluminum or something to fill the big hole at the bottom of the new tip(where the factory tip should come out) but IMHO it's not that noticeable so no biggie.
