Magnaflow Exhaust Problems HELPPPP!!!!

[SSGHOST1]

Does anyone have the magnaflow competion series exhaust installed on an LS3 convertible? Catback or Axleback?

Went to have part #15093 installed today and it did not line up at all!!

Magnaflow tech support stated that their engineering department says all 2011 and up vehicles have valve assemblies(FLAPPERS) on the exhaust. I informed him that was not true it is only on L99's(automatics) with AFM. He sounded flabbergasted.... Needless to say they have opened a file on my problem and in mean time I am in limbo for who knows how long... So I brought The SSGHOST back home with no exhaust from axle back.

Anybody have any info or suggestions?

I installed the axle back in the garage with a friend a couple years ago, it was pretty easy.

It is definitely easy on automatic coupes but convertibles have bracing under them and the fitment has to be exact.

We just made cuts until it lined up properly.

Again this is not about cuts, it is about the angles the inlet pipes must have to avoid the the braces for a convertible. They seem to have their own in house questions about the system for convertibles.. at least axle back anyway.

If it was that simple we would have just cut til it fit but the problem is the way it is angled or mandrel bent... my driver side was sitting on the differential and the the brace. The passenger side inlet tubing was facing the side of the car!!
