Whos done a single cat in I-pipe? Did it take away the fuel smell? The fuel smell is killing me!! and I'm tired of hearing about how I always smell of fuel. plus it cant be good for keeping brain cells. Doesn't it cause cancer actually? lol. So I'm going to run dual cutouts up front when I want to run WOT. The cat is strictly to get rid of the fuel smell when daily driving/cruising. I can't fit dual cats and cutouts in a y-pipe so I've decided to run dual cutouts and a single cat in the i-pipe. Anyone done this with good results (good results meaning smell of fuel is gone or greatly reduced??)
I've read that the cats cant get hot enough in the i-pipe to "do their job." No offense to mother nature but I'm not concerned with emissions (thats what my 95 Honda DD is for
), I just want the fuel smell gone. Does the exhaust being hot allow the cat to reduce emissions and therefore fuel? Can anyone prove that the cat doesn't do a good job in the i-pipe? Who's done it???
Which cats are good for reducing the fuel smell? I could give two ***** about flow, thats a mute point. I would think that the "high-flow" cats would suck at this.
How big is the intermediate pipe on a stock Z28 muffler? How big is a stock cat? I might just put a stock catalytic convertor back on.

my true duals had Magnaflow cats in the H pipe and it still smelled like gas....my ORY and Corsa exhaust doesn't smell any different than my TD's with cats smelled. I'm going to have to buy a different DD, as I really don't want to have to dry clean my suits every week.

Something must be wrong. I do not have the smell of fun with my car. The only time I have seen that is when a car runs pig rich. What is ur air/fuel ratio. I run 14.6 and have no smell. Sounds like a little tuneing could fix that better than a cat. And might get you a few more MPG.
