I`ve just install my OBX headers, it was a 2 day job needed modifications on the factory cats, X pipe install to. First 2 resonators deleted and dual tips install.

Conclusion: Great sound at high RPM, more power, great look

 

Nice, do you have a sound clip or pic? Also why was the install 2 days and can you elaborate on what mods were needed on the factory cats?
Thanks in advance.

 

I was wondering where you purchased this and do you have any pictures. I have a c300 sport and I am trying to make the exhaust sound alot beter

 

is it for the M276 Engine where did you get them from
