Good Morning,

I installed Cold Air Intake, HKS Hi Power Catback Exhaust and Berkin Test Pipes Non Resonated. When at idle and I rev my engine it sounds amazing but when the rpm drop and throttle down or accelerate out of 1st and 2nd gear. I hears a sneeze like sound or i guess rasp from the exhaust. How do I get rid of that noise?

 

Unfortunately that's the nature of the VQ engine. So it's normal. You can tamp it down with HFC or adding resonators somewhere or even motordyne art pipes

 

Is your Y pipe stock?

 

Do some research on here and YouTube. This is typical.

 

Exhaustbl will warm down as it breaks in give it some miles

 

Wha wha what?!
