Lee, if you're not after too much louder, I would say the TORS fit the bill. Alternatively, try taking a baffle out of the stock pipes with a hole-cutting saw.
As mentioned in my first post, I live in a small cul-de-sac and I come and go at all hours. I've asked the neighbours and no-one has any complaints. Some of the more enlightened ones really like the sound.
Hopefully, sometime soon, I'll be riding to see Ant in Birmingham to do a side-by-side comparison/recording with his Tridents. Greg may also be there with his Emgos. We'll be putting the video/recording online for others to review. If anyone would like to come with another brand, or stock, it'd be a fantastic comparison.
