Guys, I am actually doing turbo back (bridge) downpipes right now on my S63 Coupe. Ordered from
a German company called HMS Tuning (they supply these bridges to GAD motors, too).
I already have a RENNtech stage 2 ecu tune (699BHP/1050NM) and a full exhaust including downpipes with 200 cel cats.
exhaust gas collector/headers MB S 63 AMG Coupé C217 5.5 Biturbo
HMS exhaust gas collector/header of stainless steel 1.4301 2 x 70 mm dia Set for left and right *** Hint:
did you test the power increase with bridge pipes?
@ GMBALL
Yes, I actually did. With all my mods the HMS bridge pipes alone added roughly about 30 BHP. I am soon going to dyno my car again, this time to measure gains after installing my blackboost m157 CAI.
Regarding the bridge pipes. I tested with a friend of mine who owns stock AMG GTS, same runs, location and temperature, before and after the installation of bridge pipes. The difference is significant. Not as much as on the video above, but my car delivered power more consistently, especially mid-high range, resulting in him not being able to hang with me, while previously it was closer. I have both runs (before & after) on the video.
One other mod that I strongly recommend is the TCU tune. I did Weistec TCU. Helped a lot. As you know on AWD M157 cars transmission is el. limited to 900NM thus lowering the torque and acceleration. After the tune it really opened up. Must do if you take modding seriously.
I'm excited to let you guys know I got a set of AWD Turboback pipes on the way. Unfortunately a few years ago my E63 got totaled. Since then I have missed the power and sound of the Turboback pipes so, I will be doing the same on my CLS63S. Stay tuned for turbopipes on e50 with an eventual TMIC setup.
👍🏾

Glad you shared the Links to the Threads associated with those failed products. as you mentioned all companies have their bad eggs, It looks like generally there are very few issues with their products across all platforms.
Im not here to argue with the forum accountant. Noone came in here to attack you, Go back to whatever you were doing before your lid popped off, let the adults have an informed conversation
@Raptorpower700 shoot me an email, I will send the downpipes with bridges to you for $1150, but you will need the weistec upper mount
