hey guys i just got my header and downpipe installed and i hear like a clicking noise when i accelerate which gets louder at higher rpm's... is it just it breaking in and will it go away?? any ideas as what it could be??? i got it installed by a mechanic soo it shouldnt be leaking it was a direct bolt up.......thanks in advance

 

I Had The Same Problem My Header Was Leakin All I Had To Do Was Just Retightin The Bolts And It Went Away So Just Snug Them All Up I Should Go Away

 

wouldn't it throw a code if it was leaking??

 

Not Really Mine Didnt Throw A Code Every Now And Again It Throws It For The Hiflow Cat

BIG-DAVE....wat do you do when your cat throws a code?

 

you have a 3" downpipe?

 

I Have A Dash Hawk And I Just Clear It

 

ok so i took my car to another mechanic and he says its not leaking, but i still hear like a tin-can-like almost rattling noise i guess u could say....when i got my downpipe i saw one of the sections on the side of heat shield on the cat was not crimped down all the way...could that be making the noise??? like the two peices pinging against each of making that noise???

 

Oh yea the heat shield sounds just like that. Mine isnt even bolted to the car anymore...its just hanging on the exhaust about to fall off. Rattles loud as **** everytime my car is in low rpm's

 

well if i get it welded all the way or crimped down, would the noise go away??
