Hey guys,

just registered as a sponsor there, and thought I would share a video of our Project C63 AMG and the new exhaust note (valve on/off).

Full IPE System with Eurocharged Tune, and MFactory Helical LSD (more info on our LSD here: https://mbworld.org/forums/c63-amg-w...eady-ship.html)
Been a long day. Final result: 573hp/520lbft (We're in the UK, so figures are at the flywheel)

Music to my ears.

FML nearly every 63 that has long tube manifolds and a tune from MSL comes out with 570hp. I'm so jealous.

I'm curious - was not aware that UK testers report power at the crank. You're clearly measuring at the wheels. How do you adjust?

that sound will either shut the neighbours up...or raise hell. love it!

YCW

Most of the world reports at the crank; it's really only North America where they do it at the wheels (hence we say bhp, not whp). As this is mainly a US-Based forum, this is why most will talk in whp. The calculation is done by the dyno software, and is normally around 18-20% drivetrain loss for RWD's.

That's the good thing about the IPE system, as it has a controller so you can turn the exhaust valve on/off when you require. With the valve closed, it's very quiet (apart from cold-start, which WILL wake all the neighbours up! lol)

I actually find my IPE at Cold Start quieter than my OEM Exhaust at cold start.

YCW

You probably have it set to have the valve closed as default?

Mines is wired in to start with the valve open.

Phil Chow

Actually, I picked mine up used. The Controller is a little retarded, so the AUTO Function actually doesn't work, and whatever setting I left it in when I turned the car off, it'll start in that setting.

But, I close my valves when I enter my complex anyways, just to be courteous. I left it open once, and the next day I cold started, felt so bad, immediately closed them, haha.

YCW

Yeah, the Auto function doesn't work on mine neither
