There seems to be a rattling noise coming from inside the cat... anyone know what this means? also my exhaust sounds like a truck now the sound got like 10x deeper when this rattling from inside the cat started. bbk catted h pipe.

Sounds like the mesh busted and is rattling around somehow?

Are your heat shields okay? Sure it's not your muffler or an exhaust hanger rattling on your tips?

nah the exhaust is solid i tryed shaking the exhaust to see if it was a hanger because that was 1st thought. My exhaust is on there solid rarely moves. I bought it used a while back and the heatshield were a little bit damaged because of speed bumps and i have scraped them myself going over speed bumps but i havent gone over any speed bumps in over 3 months now.. and it just happened all of the sudden. I think your right about the mesh in the cat i think its lose and thats what is rattling... does anyone know where i can get some cheap high flow cats for maybe $50 shipped and does anyone know how much a muffler shop would ask for the install/welding. Its definantly not the mufler the noise is coming right from the driver side cat

just a side note beside the rattling it sounds so mean now =] i love h pipes hehe

make your your h-pipe is tight... my friend has a catted xpipe and he thought his cat was busted and he took it to a muffler shop and they said his xpipe was just a lil loose and they tightend it for him and no more rattleing...

its not loose when i install something on my car its solid.

odd thing was the rattling noise went away just out of the blue and now my car sounds slow again =[
