I don't think this is strictly true. Others have done it already, but you have to move the gas tank one notch to fit the exhaust out the back on the driver's side.

Dual exhaust should not be a problem on this car. >Brian _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
