Default Update:

I have since put long tube headers on it without cats. At the same time, I Seafoamed the intake, changed the oil, changed the plugs and wires, put in new O2 sensors, put a new radiator in it, and put Z51 sway bars w/ metal endlinks...all my endlinks were shot. The headers, x pipe and catbacks are all line up perfect now and are not touching anything. I retuned it with my Predator...and it hasn't made the rumble noise ever since. I believe it was the exhaust resting up against the transmission that was making the rumbling noise that I was hearing. I really appreciate everyone's response and suggestions in helping me solve my problem. Thanks.

Default Another thing...

If you want to hear what the exhaust sounds like now, go to Youtube and put in Corvette C5 exaust sound- OBX long tube headers. I have several videos on there under MyNavyBlue2001.

I didn't like spending $200+ for a new alternator, but I found one on Ebay for $135 shipped so I bought it (he has two more). Installed it last night and she is quiet and purring smoothly.

I have the rumble as well, on my 99 A4; but I figure it is due to me having solid motor mounts, and a solid coupling in my torque tube...
