Does anyone in the LA area have a Larini exhaust and/or FD springs in their car?

I've listened to the Larini clips on the Formula Dynamics site, and I've talked to Jeff at length, but I'd love to hear the exhaust in person and get a sense of how the ride is altered with the springs. What do you guys think about the sound of the Larini exhaust? I don't want to go boy racer, and the engine growl is a lovely sound to me, but Jeff has said that between the mufflers and cross-over, 10-20hp increase and more torque at lower rpms can be expected. If anyone is in LA and would be willing to meet so I could have a listen, that would be great, and I'd be more than happy to buy coffee/breakfast/lunch. Any input from this knowledgable body is appreciated. Thanks
