350z performance woes
Well, recently I replaced my cheap test pipes with kinetix high flow cats. All was good, but it feels a lot slower for some reason. Is this even possible? I can't think of a logical reason why there'd be a dramatic difference especially considering they're HFC. i started to hear rattling and it turned out to be the heat shields making contact with the HFCs, so I removed them as well. heat soak issue bc of heat shield removal or just my car having a few bad days? I'd appreciate any input. I tried doing research but couldn't find much. Any suggestions?
thank you

you added restriction, so yeah you will get a little loss of power.
also, keep your eye on the kinetix... i had some that cracked on me. when i called them about the lifetime warranty, they told me to send it in and they would weld it and send it back. i told them i wanted a new one, and for them to send it and i would send broken one back once it was off... they wouldnt. then they told me that i would be cheaper for me to take it to local muffler shop and have them weld it, vs shipping. needless to say, they were off my car and replaced with ART pipes within 2 weeks

Turns out I needed a tune. Jon at Z1 hooked me up, my car was apparently going into limp mode or something of that sort. Car runs better than ever now!
thanks everyone.
