I welded up a beefier steel plate bracket that no longers breaks. My plan is to completely rebuild the side pipes with new Classic Chambered packed tubes, new turnouts, and fabricate new brackets before I send of to North Carolina for Ceramic Jet Coating.
Did you add this front mounting bracket or was it part of your original kit? Or thinking more about it, is what I see on your video just past the collector an O2 sensor for your EFI?
BTW, sounds great! My concern is I have a stroked 351W, larger than normal cam and the engine dynoed at 442 HP when my engine builder tested in on the dyno. Even though it's still technically a Small Block, the sound with the stock CR mufflers is very loud. More than enough power (if you can ever say that) for this lightweight car. Hell, my 2010 C6 Vette has 434 HP and it's a blast drive and weighs almost 1000lbs more.

Moore_rb,
I watched your video again and realized the piece I saw just past the collector is an O2 sensor. Thanks again.
I am still wondering if anyone else has ever had a problem with the this rear bracket breaking? I triple checked all engine mounts and trans mounts and all are good. Just the massive force on hard launches causes enough flex in the sidepipe to break the thin bracket material. I'll TIG together some new ones from thicker guage steel when I remake the pipes. Also interesting is that I only ever broke the driver side rear bracket.
