Removeable Test Pipes*

and


C63 AMG Highflow Cats

I am Jeff

Yes, you should definitely order it if you don't want to smell raw exhaust fumes. The sacrifice of 10-15whp is more than worth it.

thanks bro

siemon

what about cheek engine should i order high cat flow and removable test pipe or doesnt matter ?

unagi1

Or...you could drive around with the windows up all the time...

Honestly, If you ordered from MBH, they should be answering these types of questions...should be filed under "product support"

Or use the "Search" function.

im already search but im not find the solution

siemon

no one give experince with this headers if he is order high flow or with out

VividRacing

You should get highflow cats if you do not want issues with emissions and your check engine light on. Add the removable test pipes if you plan to track your car or do a lot of spirited driving.

siemon

MBH customer service is very bad im not understand till now what benefit for high cats flow and removable test pipe what he dose with or with out its become check engine on

Check your inbox.

With the HFC, you will not have the check engine light on.

Hey I will be taking of cats and installing a pipe with a o2 cat sensor thread so I can hook up o2 but the o2 sensor will just be feeling pressure
Will my light Engine light come on

Mort

If you remove your primary cats (the front ones) you will get a CEL even if the rear O2 sensor is installed and working. The rear sensor will sense that the readings are not consistent enough and will set a code.

The above conversation is misleading. If you install headers, you also need a corresponding engine re-tune (a so called header tune). Such a tune normally takes care of the check engine light - independent of whether you use high flow cats or not.
