I haven't fully unpackaged it so I only took a peak. This is my first car exhaust so I can really only compare it to my leo vince full system on my R6. I'm expecting the Leo Vince to be higher quality since it cost twice as much and is less than half the material but I'll have a better idea of the quality tonight once fully unboxed.

Installed the cat back tonight, it sounds great at idle. Deeper than I expected which is a plus. I ran into an issue as I began the first test drive. As the car starts to roll forward something starts banging. It sounds kind of like a jack in the box and is pretty tinny. Its dark and late so I wasn't able to figure out the problem or how to fix it. Anyone have any suggestions or ideas as to where the problem may lie?

On another note, the cats were not coming off easily so I gave up for now. Will work on those another day.

Did you removed emissions canister shield located on the passenger side rear bumper because if you don't remove it the muffler will hit it.

Found another issue. Its rubbing on a driveline knuckle where it goes into the diff. not sure how to fix other than cut one of the supporting bars on the piece between the muffler and flex pipes.

That's not good did removing the emission sheild fix the first issue you were having?

We found out that the factory weld one of the support bracket out of four on the mid pipe at the wrong location.We are going to totally remove one of the support brackets located on the mid pipe so that bracket will not touch the driveline knuckle anymore.

New lower price is 499 shipped your only chance to get this exhaust at this price because one of the bracket will be removed, after this shipment is sold out, price will go back up to 650.

Quick update. I got everything back together moments befor my softball game so I took the car to the Fields. It sounds fantastic. It is not loud but as my buddy says it sounds like a beast under load. I would also describe it as sounding mean. Several of my friends that were helping out today said they love the sound. I did not have any drone at any speed. I have not yet installed the cats so this is with cat back only. I will take another crack at the hfcs on Saturday.

As Thomas (NissanGeneration) said I had two issues. First is the black exhaust canister sheild on the passenger rear bumper needed to be removed due to possible rubbing issues. The second and more critical issue was that one of the support brackets on the mid pipe was welded too high and was coming in contact with the driveline knuckle where it meets the rear diff. The simple solution was to cut the bracket off and now its good to go.

Thomas (NissanGeneration) was extremely responsive and helpful with all my questions. This is some of the best customer service I have ever received. I PM'd him after business hours twice and both times he got back to me via PM, email and phone within 15 minutes. Thank you Thomas.

The only other finishing touch I need to do is find a way to push the passenger side muffler tip in. I prefer it flush with the body but its sticking out maybe 1cm. The tip just doesn't quite have enough adjustment but this is a very minor detail.

My friend shot a quick in car video with his phone. It really does not do the exhaust justice. Its actually pretty deep sounding in person.

Hey buddah does yours have an H pipe up front? From the pics I never saw an H pipe not that I care I prefer that it has it just wondering if it will an exhaust leak since it just slips together?

Yes its an H pipe. I didn't look that closely, does the part that connects the two pipes open into them or is it just there for support? Either way, no leaks so far. I'm going to check again this weekend for leaks and the re-torque the bolts if necessary. I should have better pics and video up in a few days as well. I may wit till my gopro gets her early next week though.
