humm lady needs advice
 
owner of a 2007 H3 Adventure Auto, recently put Viper Branches on car after discovering original manifold had 10cm crack in it, now getting a very bad smell, almost like sulfur (rotten eggs) when I drive the car especially when speeding up. Does anyone know what causes this smell? Its my understanding that the cat converter has been removed. Thx

it sounds,(smells) like an old cat huh? the new oem cats smell sweet, pleasant so maybe there is an old cat, somewhere?, in the new manifold? old technology?

you could ask the guy who sold it huh?

yeah -get it inspected
I had a similar issue with an Audi 5000... One day I was driving and smelled something like chicken or something cooking. But only after I driven a certain distance. Long story short... I somehow hit a bat which got lodged between the radiator and the grill. When the radiator heated up, it was cooking the bat which the aroma was flowing into the cabin of the vehicle
