Bad weld job might have something (or everything) to do with the last two

 

I was just looking around on here, and I was wondering If there was any way of getting rid of the exhaust smell without putting regular cats back on it. Would hi flow cats get rid of the exhaust smell? Any thoughts would be greatly appreciated

 

Yes hi flow cats would definitely help get rid of the "raw" exhaust smell you have from running no cats at all.
