I'm noticing all the same as you Rex. the car is LOUD on initial startup idling at 2k 'till it warms up a bit or I get moving, then it settles down and very quiet at a warmed up idle. My left tip sticks out too. I haven't been under the car to try to adjust it since putting the front and over pipes on though.
On the broken bolts, Cad plated steel becomes brittle from exposure to temps above 450f, but I wouldn't think bolts on the flanges would get that hot, and even an embrittled bolt should hold fine with the low torque requirement. My guess is the mechanic over torqued the bolts, doesn't seem unlikely from the other mistakes made on the install. No one is perfect though, I forgot about the collars and put them on after my first short test drive. I also had to redo the v-band joints 'cause of a bit of weld spatter I didn't see the first time prevented the rear joint from sealing. I can't wait for warmer weather so I can drive with the windows down. I get to hear just a tiny bit of the outside sound getting to work passing through a security gate or when leaving a toll booth, but then it's window closed again. |

That's user-adjustable. Loosen everything from the cat back, push the tips in to where they are even, then tighten everything starting at the cat making your way towards the tips. As you make your way back, be sure that the tips are still even and make adjustments as need be.

I should say that I was aware of the tips being uneven prior to ordering, and had read plenty of recommendations on how to avoid it (and some people that couldn't). So I'm not surprised, but it is disappointing.
Not that I give a crap when I'm behind the wheel. |

Try overcompensating for the difference before tightening, so that when it's tightened it moves back to center?

I will make a better free rev video tomorrow. Will do start up of cold, warm, cold rev, and warm rev
hopefully i can get someone to help me do drive by's soon -side note, it might sound different now that I've tracked the car... the front pipe to over pipe bolt has yet snapped again... but this time i'm assuming the heat has snapped both bolts. Also, I've noticed that the replacement bolts were longer. Finally I get the right sized bolts... No wonder they kept on snapping!!! Seems like I'm the only one snapping bolts around here. thanks @PERRIN for the customer service yet again :happy0180:
