My wife's bike has stock pipes, she loves it. A friend has similar bike with baffles cut out, she hates it. It's a personal thing. When I get another bike I will probably stay with stock pipes. This is a very volatile issue for some. Your slash cut pipes look great. If you modify them and don't like the result you are screwed. A lot of riders feel pressure to add pipes because their buddies kid them about how quiet their bikes are. Stand your ground and do it however you decide. Oh, very few riders will admit that any modification doesn't work. That's human nature. I have not run into anyone who will admit that their modified stock or aftermarket pipes sound bad. It always.."I love the sound!" BTW.... My 3" Big Straights sound awful. They are LOUD, but that's about it. Some like loud, some don't, it's your call.
