just asking about the problems as in the ringing noise that is coming from the piping.

possibly the flex pipe cuz bitter said it was raspy, perhaps mine is defective..i saw some metallic strands sticking out sooooo..i duno.

ic komail, at least its not just me.

im going to see what i can do bout this.

i duno if my main header gasket is leaking or not, i'm gonna have to run some seafoam or somethin thru..if it is, imma just get a new gasket at toyota along with the clear tundra courtesy lights for meh doors

so the where do u suspect the hissing is coming from? the flex pipe or perhaps just the header gasket?

for the hissing, start your car up, and put it about 2 feet up on a hoist....then kinda feel around for any leaks, also check for black stains on the gaskets....i had some staining on my main header gasket...other than that everything else is good, slight power increases from 2-3 shift as well....same gas mpg...

disable fuel and spark (pull pcm fuse), plug the exhaust with rags, crank the engine over a couple times while someone sprays with soapy water on all joints and welds.

So do you need to have the 2nd o2 sensor installed or just leave it off?

your engine light will probably come on with it uninstaled...may come on with it installed as well. if the header is replacing the precat then yea you'll have a ligth on and need to use a fouler to trick the light off.

My exhaust goes Header to Straight-Pipe to Resonator to Muffler(no catalytic converters). My car is 94 st OBD-1. So my question is: should I have the exhuast shop weld a bung in my header for the second o2 sensor or leave it off and get a fouler?

what happened to the cat?
