Two days ago I install AMG exhaust. The sound is amazing [:0] .You can see on pic how it looks.
I also upgrade my ECU in Vath (german company). Now I have ~310HP and ~380Nm. I haven't opportunity to check extra power because weather is really bad.

exhaust cost me about 1200 Euro, and I didn't buy new bumper because on orginal AMG bumper (on 2 pipe) is mark how to cut for 4 pipe exhaust, so you have to only order black screen (this black plastic between exhaust)

The sound is awesome and incredible. Do you have the MB part number of the exhaust ? I am looking to get one but my MB dealer is hunting for the part number.

mark on the bumper are on front side, You have to take off black plastic screen (easy job) and then you see mark on the bumper. You dont have to paint bumper, just cut and replace black screen which cover your cutting job [:D]

bumper is in color of the car (I dont understend your question)

This is my ride, from ~85km/h to 200km/h [}:)]
(driving on C mode with bad weather, winter tires)

I don't know about the warranty but I suspect it would void the motor insurance ( in the UK anyay ), unless you informed the insurance company, and paid any possible increase.

Does the extra horsepower make any noticeable difference? Does it pick up quicker, feel faster, how does the 7G gearbox cope?

I assume some of that sound is a result of the ECU upgrade too.

I upgrade my ECU in Vath company. When I install ECU in my car (because I have to send my ECU to germany - they need 1 day to change program) I really feel difference!! I don't know real time from 0 to 100km/h because I have winter tires and weather is bad, but I check speed from 85 to 200km/h to previous time before upgrade ECU:

Before 80-200km/h ~17,969 (oem exhaust and ECU)
After 80-200km/h ~13,734 (AMG exhaust and Vath ECU)

I think my time from 0 to 100km/h will be ~5,1. I have done about 300km on new ECU program and gearbox working very good without any problem. Car is more powerful in normal driving/racing. Now I'm really happy! is only one minus of this new power in my car, my car need about 1 liter more gas per 100km. [8)]

wow...that's a significant gain in horsepower! have you considered to dyno your car to verify the results? that would be neat...[:)]

btw...the car looks great with the quad exhaust...a definate must-have for every R171...[:D]

Can you provide details about the ECU Upgrade? Where you got it done, will they do it for someone in the US? How much? Do you have a website or contact info?

I've heard so many bad stories about the r171 info.UK company, I am afraid I'll have my ECU missing for weeks.

I am very interested in the ECU upgrade, please share info.

Don't even consider r171.uk.... I don't have trust to this company.

I upgrade my ECU in Vath (http://www.vaeth.com/)
