You really want to eliminate the smell? Put cats on it.
I put cats on my '76 GMC Motorhome, which has a Sniper 2. Have cats on my '63 Impala with a Holley Terminator Stealth. In both cases, I got sick of smelling like, and smelling, exhaust. In those cases, the 455 and 409, respectively, lost zero throttle response, fuel economy, or drivability. I'm out about $600 in total, for both cars (pair of Magnaflow, high-flow cats in each), I can take my wife out for a cruise and neither of us smell like unburned hydrocarbons. It will change your exhaust tone a little. I also run them on my LS Swapped, '86 C10. I've gotten various responses from local inspection stations here in NY as to if I need them on that vehicle or not. Being a heavy-half, in NY, you get told yes and no, depending on who you ask.
My old solid cam C1? That stinks, as it should, but anything where I want to *go* somewhere, in a level of comfort, and get out not smelling like a Mobil station, I stuck cats on. They're not a performance loss anymore, don't weigh much, and are the surest way to eliminate those smells, exactly as they were designed to, for the last 50 years.
Then the Sniper can do as it wishes, and as long as it's not terminally rich, it'll have little effect on the cat.
And, no, I'm not mandated to do so by my state, just choose to solve the problem my wife (and I, as I age) brought to my attention years ago...
