just something ive been wondering.... sometimes when i crank the car up it starts crazy loud, meaning the exhaust lets out a huge roar, other times it starts up nice and easy, quietly. wut could cause the difference in the sounds wen the car starts? this is nothing serious, i dont mind either one, just curious to know y it does this, and plus wen it starts loudly all the alarms around my car start beeping, lol! could it be something as simple as like pressure build-up (idk.. just made something up)??

 

my car roars as well ... but it doesn't make the alarms go off ... lol ... but usually it starts up loud on cold starts (morning time)

 

lol, i think my muffler has something to do with the alarms though...i'll look into the cold starts thing, never kept an eye on that, i just know sometimes it does it, sometimes it doesnt

 

when you start your car runs in uber rich mode until it reaches a certain temp..

my car rumbles when cold, but smoothens out when warm.

 

mine too....i like setting alarms off its fun

 

i've never set any alarms off with my dynomax...

 

I set off alarms with my exhaust while driving.... lol

 

and that's a good thing why?

damn H4XoRZ!!

 

yes, samething, loud on cold starts, quite on warm starts
