Was out for a drive yesterday when my truck started getting really sluggish anytime I stepped on the gas. Exhaust had a funny tone to it, and truck does not want to exceed about 3500 rpms. Limped it 6 miles back to the house, and when I got out had a smell similar to rotten eggs. Did a full truck visual inspection and noticed that the 2nd cat on the right side of the exhaust was glowing bright red. It's not completely clogged yet though as some of the exhaust is still coming out the tailpipe. Just under 26K on the truck right now, and a magnaflow catback. Going to replace the 2nd cats on both pipes and am looking for suggestions. Thinking of either powersticks or maybe a cherry bomb, wanting to open up the exhaust without a straight pipe so wondering the best way to proceed.
