Thank you for your help!

My friend has a 2009 BMW M3 and wants to race me in the 1/4 mile. Who do you think would win?

Thanks,
Stan

The Jaguar looks sooo much better than the BMW he likely will be caught staring at your car and you can get a good jump on him.

Bought my 07 xkr and it came with a whole sports exhaust system. The rear muffler hasn't the valve system so the tubes underneath that used to fit on the stock exhaust valves are not used. Have noticed that each tube end has been blocked. Now not using these but should they still be unblocked to let out the vacum, .
