I have a 2003 enthusiast equipped with nismo exhaust, black CR Kai rims and tinted tailights and turn signals. But lately ive been thinking about how to make my Z sound more aggressive, dont get me wrong I love the ssound of the nismo. But what would my fellow Z owners suggest to making it louder and more aggressive? I was thinking maybe strup test pipes or berk hfc's. Any input would be appreciated.

 

yup, test pipes or HFCs would do it

 

i have a nismo exhaust and it depends on what u wanna spend, berk high flow cats will make it sound really good and clean, i had them but they failed (i am F.I. though) but if u wanna spend the extra buck and get some good power gains go with berk test pipes and motordyne xyz/w resonator is what i have and it sounds amazing and not raspy but deep and clean and loud when im on it but can still be kept semi quiet when i want to, or if u feel the need to have a cat they make the xyz w/ cat also, they are pricey but i absolutely love my setup now ...i just went to the track but forgot my camera, ill try to get a clip but wont be for few days prolly since its rainy here..

 

plus u can sell the nismo y pipe after, i just sold mine for 230 shipped and got a little money back from buying the motordyne xyz...u will get rasp with the nismo exhaust and just test pipes without the xyz/ w resonator or cat trust me....but with the high flows it sounded good till they failed on me twice...best sound yet though is the setup i have now..so mean sounding
