Time for a new mod! HFC! Expert/Experienced/Enthusiast/Everyone's Help
 

Hi everyone, I'm looking in the market for a HFC mod. Are there any opinions on which brand and where to buy it from?

Any comment or criticism is appreciated!

I was looking into buying these but I'm not really sure if it fits.

Not trying to break the bank =/ im still going to school and decided to treat my car to something nice.

the one you're looking for in the link is a Test pipe not a HFC....
the test pipe will remove OEM cats....it provides high exshust flow while the HFC will replace the OEM cats and they proivde more torque than the TEST PIPES.... the test pipes will make the exhsut louder whether you have an OEM exshust or an after market one...
these are test pipes

see the diffrence??:)

are the "resonated" test pipe very loud? i want to go the cheaper route but i dont want anything extremely loud, thats why i kept my oem exhaust =/

I don't think they will be too loud if you keep the rest of your exhaust stock... but you will get some rasp with test pipes.

will the kinetix fit on the 07+ sport sedans?

Which Kinetix product are you referring to?

that one

No it won't. That's only for the DE engines in first gen 350Z's and G35's.

edit: This is what you need
