Sounds fantastic. I just did mine after pretty much seeing every post i could on doing a muffler delete. The videos don't do it justice, i've read this a few times, now i know why. I can hear it crackle when it downshifts, especially on low speeds when it's pretty much quiet then: deep crackle crackle. I also did a H pipe right where the two exhaust pipes get attached to the muffler.

Yep mine makes that same low speed rumble/crackles when decelerating. What did the H-pipe do for you? Did it reduce some of the "chugging" noise between the cylinder banks?

Yes i thought it would blend the sound better between the banks after seeing a few pictures with H-Pipes.

Quick question, excuse me if I missed it. Did you keep the stock resonators that are right after the cats or did you straight pipe from the cats back?

The only thing part of the exhaust removed was the rear muffler. You can see the clamps in a couple of the pictures, that's where I cut the stock tubes. This allows me to go back to stock easily.
