i used to have Larini's on mine but the vibration at idle and the drone meant they didn't last long (actually I had the dealer remove them before I even bought the car). After much I went for a custom system - Prospeed exhausts in Cardiff. It cost £1200 and the fabricated and fitted a complete custom system in a day - so I have backboxes and sports cats. It sounds great - much more grumble at low revs and a great sound at high revs. No drone, and when idling it's a nice sound not too over the top. A great solution all in all. Only downside is that you can't easily hear before you buy (though you're welcome to come listen to mine - Wimbledon area - it won't necessarily be exactly what you get as they're not off-the-shelf). Plus you need to go to Cardiff for them - I did it in one long day - left home at 6am, there by 9:00, spent the day shopping and then returned at 5:30 to collect the car. I would recommend them.
Cheers,
Ben.
MIJs £250 2 years ago, welded on...Autoshield also did a forum deal of I think £550....but changeable and far better quality

Don't know what's on mine or how they sound from outside (useful huh) but there's no hint of drone at any speed
Just a lovely singing noise
