I test road a Vic identical to the one I bought, identical EXCEPT for the exhaust. The one I test road had Atom bomb pipes, and I tell ya, I did not like them and neither did my wife. After just a half hour my ears were ringing, couldn't listen to the stereo at all it was just drowned out by the pipes. If you wanna go prematurely deaf and if you don't want to be able to hear the radio or police/ambulance/fire engines siren or other cars that may be honking at you in an attempt to alert you to danger, then go for it, otherwise, I personally went with the factory exhaust. Wife and I can communicate, hear the radio, or sirens or horns, and my ears don't ring after just a short trip. Just my .02 on the Atom bombs (appropriately named I assure you).
