you can turn them off with the tuner. you can also get MIL eliminators. my tuner just turned mine off with the dyno tune.

 

mine have bung plugs in them. but you can put your O2 sensors in them too. the rattle, sounds like something is loose? you might want to check the connections again. I always check them periodically, especially after i change something after about a week to see if its on good.

 

I have the long tubes and off road h-pipe. Gained power right off the jack stands and sounds incredible. Rasp is probably related to the muffler. Magnaflows don't seem to contribute to rasp. A custom tune helped tweak more power out of it.

 

ok i got it all sorted out it turns out that there was a piece of scrap metal wedged in between the primaries and the collector so i had to pull the header out of the car and pry the fu*#in scrap metal out it was a bi#%h but i got it all back 2gether and they really do sound great

 

congrats man, glad you were able to diagnose the problem
