hey everyone.
i am thinking about running my 2004 hemi with a flowmaster and cutting out the cats. I need to know if it would sound good and is it going to turn my engine light on and if it will mess my engine up doing this????

thanks

 

It will be loud.

Yes, you will get a check engine light unless you get O2 sims.

 

where do you get those at

 

It will be loud!!!

 

you can use spark plug non foulers to back the o2 sensors out of the exhaust flow...

 

will that make it where the engine light will not come on

 

from what i hear that should keep it off..

 

Very good TD, it's apparent that you have memory retention for what you have read. I don't think your as dumb as everybody here says you are.

Any parts store should have them, and yes, in about 95% of the time, it gets rid of the CEL.

 

why would you do that?? some back pressure is needed, if you have none you'll be slow as **** down lown

 

aight thanks everyone
