any good reviews about this product?

not sure which one sounds better

the Apexi N1 EVO Catback Exhaust Nissan 350Z

or NISMO.

they both look very similar.

 

IONO, allot of people seem to like the Apexi for the Z. On all my other cars Apexi has been really loud and obnoxious but i guess its diff on our cars. Everyone will vouch for the Nismo and tell you its sound is awesome. Its really exotic when the N1 is more of the typical exhaust sound, just louder than stock. Id go with the Nismo if i made a choice between those two tho.

 

I haven't had a chance to compare these two in person.

I've never heard any APEX-i, on my other cars I've had Tanabe, Greddy, and always preferred Greddy for it's deep tone and not so obnoxious CIVIC CAN buzz.

 

The n1 based setups for the Z are quite loud..the World Sport is relatively quiet

 

I believe you are thinking of the Apex'i World Sport 2. The N1 has two big cans and looks nothing like the Nismo, it is also very loud. The Apex'i WS2 looks like a great exhaust for someone who wants something nice and quiet, and ive heard nothing but good things about it.
