is this possible on the es350? also is there any way to make the exhaust a little throatier without some ricy exhaust pipes?

 

Sacrilege - why take such a beautifully engineered QUIET car and try to make it sound like an Integra?

 

I agree that it's not something I'd personally do, but a V6 exhaust is distinctly different than one on an inline 4.

Directed (the manufacturer of Viper, Clifford, and a number of other systems, would be the place to look for the remote start: http://www.directed.com/ My guess would be that this isn't possible, at least not without keeping a programmed fob somewhere in the car. But then again, their website has a Lexus RX on the main page, so who knows?

Exhaust...anything can be done. If it's something you really want to do I'd recommend following some of the sponsor links on this site and maybe talking to a motorsports or exhaust shop in your area. I've heard some V6 systems with Magnaflow mufflers that sounded surprisingly good. Beyond that brand name, you may have to look more exotic - Borla, Bassani, B&B, etc.
