Yes you can. I have the Magnaflow 12158 with the stock tips. The installer at the exhaust shop did have a difficult time getting the tips back on and aligned properly, but he finally managed to do so. It looks good and sounds great. If you go to youtube and enter crossfire 12158, you can see and hear my black Crossfire with this setup. I have to add that it actually sounds better in person than on the videos.
