Anybody with the down pipe after the install get a exhaust leak type noise?I started the car and got under it and there were no leaks,i'm guessing it's internal

Bump

 

does it sound like its coming from right side kinda where the header is? and it gets louder in upper rpms?

 

Yeah

 

hmm check the header flange...have a buddy help u out..rev the engine up and ull feel it.

 

Anybody else?

 

lol my CA header makes that sound.. i dont have the dp installed yet (sitting on my floor) but i got it checked out and they said its not an exhaust leak, but that its an echo of the noise off of the bay or some crap like that. im hoping that when i install the dp it goes away. maybe they hit something they werent supposed to and the same happened to u. do u have a header btw? i dont see it in ur sig, but neither is the dp on there.

 

I don't have a header but i guess i need someone to get on the gas when i'm under the car because i got under when i had the car on and couldn't find an exhaust leak anywhere.

 

nah, its nothing.. i have the same thing.. if it was an exhaust leak up top like by the header it would be loud as ****... i noticed that noise for awhile until i got my loud ass exhaust on and motor n transmounts couldnt' hear **** then

 

Oh and the car hums like crazy when i get on the gas,i'm guessing because i have no cat.
