i need a better sound..thoughts?

 

Remove the resonators is a cheap option. Renntech, Supersprint, Eisenmann all make great exhausts. I would also get a set of headers to finish it, they add quite the sound!

 

anyone know where around tampa area i can find a shop to remove resonators? will merc do it?

 

Call chris at C2 Design

One of the nicest Mercedes shops in the Fla.

If you are looking for power, I would say dont do it. If you just want sound, you will notice a difference!

 

just sound..i do not believe any of the performance gain numbers...

 

Ive seen real gains on an E63, stock versus Renntech headers and mufflers, no ECU tune, same day install. If you just want sound, removing the resonators will add a little more growl. You will also lose power with them, I know a couple sources that say the same. Resonators remove the resonance in the exhaust, and you lose exhaust velocity, which means you lose power.

 

Renntech headers or Kleemann, both are great , remove the charcoal filters and drop in some bmc's, go for the tune which you header supplier provides, sport primary 200 cell catalytics and a VRUS X pipe to remove the resonator.

I dont think removing the resonator will result in a lose of horsepower, that is common on the M113 Evo engines which are 55K available on the CLS55 and E class.

 

Resonators absorb energy and slow down exhaust (very slightly). You don't lose power by removing resonators, especially on an NA motor.

 

I should have been more specific in the words I used.

Resonators dont actually absorb energy, but cancel it. They use sound cancellation, by using 2 sound waves to lessen or cancel their energy (if you guys remember science or physics, you know this). Glasspacks use sound absorbing materials.

Resonators are a restriction, and they keep the exhaust velocity higher. Remove them and lose some torque, but gain more mid-high range power. On the M156 engine, I would think keeping torque would be a good thing.
