I notice my exhuast on my car is pretty loud for a stock exhuast. It seems tho when i start off or put pressure on the motor it is louder in the front. I have already replaced the exhuast manifold gaskets along with Y pipe dounuts (not the cheap serramic ones) and I have a whole new exhuast cat back. I was wondering if my cat is bad, not sure if its the orignal one or not, but sounds loud by the cat and in front of the cat where the Y pipe goes up? Could the cat be no good and cause the exhuast to be very loud in the Y pipe? I also put my hand down by the Y pipe and felt around the dounut, doesn't seem to be leaking and revved the motor up with my hand there. Any ideas? How can i tell if my cat is bad? Should I take it off? Thanks guys

 

its fine. of course it gonna get loud when the rpms are up or once its starts. its becuase its rich thats all nothing to worry about

 

I decided to take it off tonight, but which CAT do i get to replace it, the direct fit for 93.00 or the universal for 65.00. What do you think would be better? I noticed that now my Y pipe moves alot up and down, is that normal or is that a problem, could that habe been why its loud? Thanks man

 

Your Y-pipe shouldn't move. It should be solid as a rock.
