Got a WARM start the other day.....Skymaster pipe....I noticed the wrinkles on the left side of the pipe.....most are located where the accordian inner and outer sepearator is located (I know some of this is normal at the attachment between the inner and outer)....the worst "wrinkles" are located around the attachement point of the strap and behind the attachment point and the beginning of the outer pipe....not sure if it is normal for a bit of deformation at the strap attachemnt point, as I have previously mounted all my pipes without using the included straps......( my real concern is the wrinkling on the inner pipe just forward of the outer wall in pic #5).....some general pics of the outer color are also included for reference.....pipe has about 10-15 starts on it......there is a very tiny hole in the pipe where part of the accordian spacer is welded to the inner pipe.....u can see this hole just to the left of the seam in a few of the pics....it is the tiny white dot about 1" from the seam......might have been there from the start.....not sure about this...... opinions from those who have had/seen worse and what the result was....never seen a collapsed pipe or what is the beginning of it looks like and how fast it happens once it starts.....Thanks.....
