Yes they do !!! All of my neighbors have lived in my neighborhood since the 70's and are much older and me and my wife are the new young ones on the block. If you look to the right in the 1st pic, thats my 93 Mustang coupe. Its a full blown NHRA chassis certified drag car. She puts out 800 supercharged horses to the wheels and does it all through two 3" bullet mufflers attached straight to the headers. You can imagine how loud that thing is !!! Then in the background of the other pics is my 04 GTO and its running straight pipes(no cats) through flowmasters so she aint quiet either. Its all good though no complaints yet
Oh yeah I just have the one 51. I don't want to turn the 51 into a race bike. I'm looking into a gsxr 750 possibly for that but it'll be next year before I pull the trigger on that.
