So I'm hearing that you actually lose HP with this exhaust-Eisenmann Race Exhaust for a E55 W211, reason being is not enough back pressure. I was in the market for one more for the deep sound, but if I'm gonna lose HP, forget it. Any have any experience with this exhaust?
Thanks guys!

 

Mine has it, and Im at 534 RW on a Dyno Dynamics
The sound alone is worth losing 10 or so HP. Get the car tuned by Powerchip
and you will see gains

 

can u post some sound clips?

btw does anyone know if that same exhaust would fit on a CLS 55?

 

Anyone hear of Meisterschaft Exhausts???

 

Yeah, "schaft" is what Eisenhaus (Eisenmann's former USA distributor) tried to do to Eisenmann by counterfeiting their products and having them manufactured in the far East. Eisenmann caught them, and terminated their distributorship. Now Eisenhaus sell their own knock-off line of exhausts. There are several previous posts on this; do a search.

 

Im no expert but back pressure is really not necessary for forced induction cars.

I have not heard anybody saying that they have lost powers with the eisenmann

 

I have the Race and there is NO drop in power. There really isn't a way to drop the back pressure enough with just the rear exhaust section to make a difference one way or the other.

Also, too little back pressure would drop your torque but you would still have an increase in top end.

FWIW, I don't have a drop n torque either.

Get the exhaust, you will love it!
