A year later... new updates! [

]
I had Dominic fab up a new cat pipe for me using a new Vibrant "race cat" which uses a stainless steel core that flows better than current ceramic core "high flow" converters. From the 3-bolt flange is a 2.5" to 3" concentric expander welded to the inlet of the converter. Two bungs are welded into the expander for the OEM O2 sensor and the wideband sensor for my AEM UEGO. The converter has a 4" body and 3" inlet/outlet, and from there is the usual S-bend to go over the subframe. Rather than use the typical 2-bolt flange to connect to the flex pipe, I opted for another v-band. Another bung is welded into the S-bend for the rear O2 monitor.
Since the flexpipe needed to be modified for the v-band and I wanted to use a longer flex section, I opted to just have a whole new flexpipe built. Again, some new Vibrant tech was employed, using a "high flow" flex section that has a true 3" ID all the way through and a smoother lining for less turbulence.
This weld shows some awesome work... the weld had to merge the outer collar, outer wire mesh, inner flex piece, and the pipe in one shot. As you can see, awesome job like always:
Every single piece is stainless steel, inside and out. I'm thrilled with it though the race cat is a bit louder than the CFM, but that will all be solved with future modifications to the exhaust. [

I also ordered some stainless nuts & bolts for the 3-bolt flange, and Dominic gave me some nice stainless studs and nuts to replace my now-rusting ones for the header's head flange. I'll have some more pics up soon. [
