Re: Hard acceleration issue
If you have any joints in your new exhaust around the area in which you think your noise is coming from, I would suspect your exhaust/timing. New headers and performance exhaust can alter tuning and a leak at a flange will make a "pop". Can be deceiving as to what the sound would be expected.
