The Corvette Central exhaust kits are nice sets of pipes. I went with a dual system with Magnaflows to replace the stock 2-1-2 system on my 1980. The Magnaflows were nice, but weren't "enough" for me so I did switch them out for a set of Flowmasters, but I have no complaints at all about the price and fitment of their kit. Nice little power bump too.

Put their muffler-welded to pipe, 2" system on my all stock '71. Excellent fit and finish.

Thanks. I did know that...had just never heard of any other non-true dual but now have learned of the 2-1-2..what a crappy idea GM!! That's what we got in that era of EPA designed cars!! ;-)

Dual Catalytic Converters for C3 Exhaust
Is it possible to add dual cats on a C3? I am avoiding the 2-1-2 system at all cost, but the smell from my L48 is killing me! Slightly raw fuel smell (along with other chemical smells) that burns the back of my throat and hangs on work clothes for days. I know I need to do a thorough tuning on my new-to-me '73, but the plugs are clean (though the exhaust tips have a little soot on them) as it is now, so I don't think it is that far off. Thoughts?
