You know how the factory put a little burble into the 2006 MCS stock exhaust ? Well for those planning a aftermarket exhaust be ready for ALOT of burble. I just got a Borla Sport exhaust on my 2006 MCS and that little burble turned into a very loud burble. If you back out of the throttle in 1st, 2nd, or 3rd gear, and between shifts there is a very loud pop,pop,pop. I'm not saying I don't like it, but it is very different than say the same Borla exhaust that I had on my 2003 MCS. I guess I will get use to it. I thought that it was built into the stock exhaust , but it must be in the motor because it really is noticable now with the Borla. Just a tip.............

 

Yup, from 05 on the run real rich to make sure we have burble.

 

No burble on my '02 until I installed the '05 Craptastic kit.

 

burble is a cool sound.

 

ya. i love it on my 05. its really unique. how many cars do you know of that come with a burble ? i cant wait till i get my new exhaust to see what it sounds like then.
