I just had an X-pipe installed with two straight through mufflers, high-flow air filters, and Race Chip tune. A very basic setup... so I thought. As the car reaches 5,000 rpm, the turbos howls louder than anything I have ever heard online. I have listened to CLS 63s with 800hp to 1200hp, and I have never heard this so called turbo howl.

Any suggestions will be appreciated. Yes, I do understand... "put the factory mufflers back on" is an answer, however, I'm looking for similar issues and successful fixes. Thank you.

Oh man, we gotta hear this! Have a sound clip? Video?

Welcome to the forums.

 

Yeah I am very interested in a sound clip or video of this.

 

It won't let me upload the MP4 video file. Do you have a person email? My computer won't convert it to another file.

you can send it to rickchiro@gmail. i'm interested in hearing it. i really think it sounds like you may have an exhaust leak from the work that was done.
