As you can see the B pipe is about an inch shy of touching the cat flange. Originally I wasn’t super worried about this since the stock cat and cat back are about an inch smaller in diameter than the 3SGE engine should be breathing through anyway. Since I haven’t ordered the material for this yet however.
A quick extension had to be made on the stock Camry cat for right now. The engine wiring is done, so quieting things down to finish check out and the transmission wiring is a necessity.
