Mercedes-Benz C63 AMG with Akrapovic exhaust sound [video]

Video shows RENNtech C74 fitted with a roaring titanium exhaust system

More auditory fun from Slovenian exhaust specialists Akrapovic, courtesy of American Mercedes-Benz tuning house RENNtech.

This video shows a RENNtech tuned Mercedes-Benz C63 AMG, the previously seen C74, fitted with an Akrapovic titanium exhaust system. You get to see the car sprint around on American roads as well as hear the full concert from those quad exhaust pipes.

The C74 by RENNtech features the AMG 6.2 liter V8 now tuned to 605 bhp (451 kW / 613 PS) and 555 lb-ft (752 Nm) of torque. Top speed on the car is 204 mph (328 km/h) but we don't expect them to show us the car doing that.

The standard C63 sounds far better.

Having had a C63 when they first came out, I found that the standard exhaust had a very nice, aggressive sound. It was actually on the verge of being too loud at times! Akrapovic makes wonderful quality products and his efforts provide work for Slovenians and an excellent image abroad. Well Done! However, as to the RENNtech "tuning" it is very doubtful that this horsepower can be reached on the standard AMG motor without very deep modifications which would adversely affect service life. I know this intimately, but will not disclose why I know this...Next, the visioning of the "performance" is grotesque. Smoking tires? To what end? A recent Youtube video shows a new Nissan GTR doing a 0 to 100 K/mH in 3.0 seconds in Japan, without any fanfare, screaming engine, nor a whiff of tire smoke. Furthermore, the view from inside is boring, this is supposed to be exciting? Sport driving? These "tuners" need to perhaps apply some "tuning" to their small brains in order to comprehend what true performance really IS.
