will adding high flow cats or test pipes to a nismo exhaust have a significant change in the loudness of the exhaust? which one should I go with?? High flow cats??? Or the test pipes???? Does Nismo make either?

Adding the high flow cats will make the exhaust much louder. I have the R/T cats on my stock exhaust and it made a huge difference in sound. I know ElDiablo is running Nismo exhaust and the R/T cats on his and it sounds mean. Dont go with test pipes though. They give a real bad raspy sound.

as far as the warranty thing goes. if nissan determines that the problem you are experiencing is caused from your modification, then they can void it. they can get picky if they want to.
i would think that an intake could be much more of a problem with the warranty than an exhaust.
i dont see why your old cat's warranty would be affected.

Whats up man?
The RT cats will make your set up with the NISMO exhaust much louder and meaner. Not to mention cats are a great Performance mod.
I kept my stock cats and advise you keep yours too, just in case you ever want to put them back on. I cant imagine you would ever want to though.
Again your Z will be way louder!
I love the sound
here is a short video I shot reving with the nismo and Rt's
If the link doesnt work try clicking
a few times. The server is crappy. eventually it should come on.

Diablo's car sounds MEAN as hell. I'm debating the test pipes and cats thing as well because test pipes are just so much cheaper. But with Hi Flow cats, u kno u can pass sniffer test and u won't have to jack up your car and put back the oem cats.

If you don't want a LOUD Z, but you do want a meaner tone. Go with Kinetix's High Flow Cats. They are AWESOME, are NOT Raspy at all, and are much cheaper than the RTs.

labree motorsports makes test pipes w/ resonators that supposedly eliminate the raspy sound, but i've never heard sound clips... and i dunno if the resonators cut power or not... i was close to getting them till i found out they were almost $400... most test pipes are in the $200-300 range at the most
