this rattle we are discussing does it sound like the heatshield is rattling? if so looks like ill be tending to my 97 soon...

it rattles when cold and when i turn the truck off, very annoying at the very least

 

does HPtuners work on something as old as mine? My friend uses it for his turbo GTP/C5, im sure i could score a few credits and use it.

 

yeah, exact same as mine. I thought it was the heatsheild on my cat itself, but when i lifted it up turned out to be inside of it.

 

98 is earliest year i do believe


i hollowed out my cat cause the insides were broke loose and rattled. I ran it without shutting off the code for a few thousand miles and never got a SES light. I then later on just shut code off and have no issues with passing emissions

 

my cat rattled to, i got a friend who took mine out and put a piece of pipe in there cause it was all i could afford at the time thats been 14,000 miles ago and 1 year and never got an ses light. It is loud as hell tho so i'm probably gonna put a cat back in soon, we dont have emissions to worry about here so i dont have to just would like it not so loud.

 

Is it loud with the factory muffler? Mine rattles and I have been debating on ordering a new one or just gutting this one. I just dont want it super loud.

 

just out of curosity, how much does this sensor spacer extender cost? and what are those 3 bushings picture in the bottom used for?
