Hi, being new to porsche I was fortunate enough to purchase a 997 c4S Recently, but one feature missing was the sports exhaust. I have been reading forums where somthing called a Gundo hack can be done to allow a small pipe to bypass the muffler to give the same rasping noise. Has anyone done this, and do you have any advise please. Currently located in Berkshire area if any recommendations come in. Thanks
