crap

walkert started a thread about it, he is running berk metallics.

 

I went from Berk TP's to Berk Metallic HFC's and couldn't be happier. And what they say about Berk being number 1 by backing their products is 100% true. My TP's cracked and they let me switch to their HFC's. The sound is awesome with no rasp.

 

any CEL problems?

 

Unless you damage your o2 sensors or put them in the wrong bung, then yo ushould get no cels at all from the metallic HFCs. Some people have received a cel for the first few minutes while warming the car up with metallic HFCs, but I've only seen this happen when they put their o2 sensor in the wrong bung.

I have had no CEL and even took my car in for emissions (OBDII and Dyno type thing required) and passed both with out a problem.

 

Well new o2 sensors and it still threw a CEL 0430. Then I jacked up the car and started it to find my left HFC just before the support bracket has CRACKED.

I am going to call Bryan and see what they will do for me. The CEL is because the air is leaking in and makeing the oxygen reading to high. So the ECU throws a 0430/0420.
