I have APS 2.5 daul exhaust. I am going to be putting on nismo headers and want to put some good HFC on.. But not sure what ones would be good. Any Ideas??

 

HFC is not a new subject but just some observations:

HFC are heavy. We see many breaking support bracket welds.

HFC have stuff inside. Eventually the stuff inside works it way loose and rattles like hell.

If you have a particular need for HFC, emissions testing for example, go HFC. If not simplify your life and go test pipes.

 

That's what I have been reading about the welds an the internals on NFC.. I have TP but don't like the rasp sound the make..
