How is the build quality?
How long have you had it and how's the fitment? why do people crack them so often? I'm still contemplating.. cell light goes away with test pipes after awhile?

 

I have posted photos and critique of Kinetix High Flow Catalytic Converters several times. If I had anything worthwhile to add, I would.

 

Test pipes hold up really well. It was my own fault that mine cracked initially. Also, the CEL will come on depending on your build date. From what I have observed 03's and early model 04's do not throw the code. The late model 04's on do throw the code more than not and the quick remedy that people have used is the non spark plug fouler method which can be searched

 

cool.. also, it appears a lot of people don't like the sound of the test pipes.
I guess helix TP is the one everyone's going for.

 

you see lots of Topspeed, Helix, Mega, APS and now the new STRUP. this topic had been discussed MANY TIMES. I'll recommend tp over hfc (consider the fact i sold my Random Technology HFC for STRUP tp.
