ok ive heard some of your guys exhaust with headers and no cats....after the rev i don hear any popping..when i rev mine i hate it cause it pops and backfires..any help for a resolution.?

 

You need to get it retune for the headers

 

i did..my truck popped when it was stock...when i got the headers and ory and my tune itstill did it..just way louder now since i dont have cats nemore. its embarassing sometimes lol when people wanna hear my truck it pops luad as f**k sometimes, more like backfiring.

 

depends on the muffler

 

well when i first got it it had the stock exhaust with a flow...popped a lil got headers and y pipe damn it popped all the time. changed to a borla was a little better but not much just a little quieter thats it. long story and i ended up with a pos flowmaster again..it freakin sucks. i was think about putting my cats back on just to stop it.

 

magnaflows really help with popping

 

mine basically stopped after i finished the tune even with my crapmaster. i think it also has something to do with DFCO because it cuts fuel when i'm off the throttle when its revving. not sure though.

 

turn dfco off

 

my truck has flows with no cats and i dont have any popping issues...i would have to say its your tune, or it could be an exhaust leak...before i got my exhaust fixed it out pop a lot under deceleration...

 

what does dfco mean? and whats its purpose?
