Hey i noticed a noise coming from the front under engine of my car at WOT. It's not that distracting of a sound or that loud. It almost sounds like a spark sound from the cat back when you give your car high rpm's and let off at idle, but not as loud and under the front not the back of the car. I highly doubt that it's an exhaust leak because the headers and flex are brand new. I havn't had my car scanned for KR yet because i've been to busy, so ill get to scanning it within the next month. My question to you is what exactly does knock sound like at WOT please be really specific (Loudness,rattle,duration,sound pitch,ect.). Cool thanks :th_thumbsup-wink:
 


Knock will be a pinging sound. If you can hear knock the engines not gonna last long. You probably have a exhaust leak. Just because the headers are new doesnt mean there sealed.
