I have a 2006 AT with headers back greddy exaust system idk if that will help but when you get into the gas my car makes a growling noise its awful and it only happens when u really get on the gas I can't seem to figure out what this is. Nor anyone else. I have no cat I have a mid pipe in my car so but please help me if possible

 

i can't help but state the obvious....

you have a midpipe, headers and exhaust...

if it DIDN'T growl, i would think something was wrong...

 

Loose heat shield.... probably.

 

Yeah we were thinking it was the heat shield Because it just started this! I have had my car for 2yrs and it has just started! But I wasnt for sure I didn't know if anyone else might have ex this problem and might could help me. Thank you so much I'm going to take it off!
