Like the title says Engine Noise: Raspy/sound @ ~2800rpm.
This has happened every since I got the car, and I've also noticed it for the many years my Grandmother had it. And its seem to have gotten more noticeable once the new headers and catback were installed. Car is in excellent shape, no leaks in the exhaust, low mileage.
The sound ONLY ever happens on acceleration up to and around 2500-3000rpm. and I can hear it mainly from the passenger side. Once I hit cruising speed it just goes away until I accelerate again.
I went for a ride with Justin L tonight and his car DOESN'T have that sound. Even with his crappy ass old exhaust never heard it. (Now he has a new borla)
I still have the stock cat, and will be ordering a high flow tonight.
I looked at this link http://www.mx6.com/forums/2g-mx6-gen...e-2500rpm.html (Raspy noise at 2500rpm.)
They think it could be the cat? Its not rattling or anything.
Could it be any bearings where the belts are? don't think so.
I've included a sound clip to best help out. Thanks.
