i have oz manual with headers and aftermarket muffler. when i turn on the car i notice that when i touch the tip of my exhaust (stock exhaut just in case} i dun have as much free flow like i should. my mom has the oz but auto stock bone and i feel as her exhaust throws more air than mine when i put my hand at the tip of the muffler. My question, is something wrong with mine? i check for exhaust leaks and so far nuthin. i search and all i found was to check the cat which so far seems ok. thanks for any input

 

No, your engine isn't under load so it's not exactly going to be pouring out exhaust.

 

if yours is more freeflow then hers then its not as restricted and doesnt force itself out more like the stock

 

And I am guessing your muffler tip is a lot bigger than her stock tip. That means the gasses are not being squeezed through as fast. Your car is fine

 

ok i get the picture now, just wanted to confirm things to make sure. thanks again
