Only thing that I don't like about the Injen is replacing the filter....since it's on the behind the grill, hard to clean or change...
that's why I'm planning to make it shorter or do something else....
when it hits over 3000~4000 rpm.......man~ I love that screaming sound!! I can really feel it's sucking the fresh air!!

 

Yes, its a larger filter, and its right under the hood....def louder

 

i just installed a pop charger today and it sounds badazz... more of a difference then i thought...i have a borla true dual though

 

That's the only problem i have is cleaning the filter, but as for sound it lets you know its working. Has any one heard bad reviews on the greddy evo 2 exhaust?

 

I have installed the Greddy Evo 2 on my 350Z track and it has killer sound.. at the high rev it sounds like a ferrari passing through.. I have also a friend who has Borla exhaust and all those who have heard both say that mine is definatly better sound... Greddy sounds very close to an M3 sound and better than M3. The borla has much louder cut off though and i liked that about the borla.. my Z gives a cut off sound only when i reach 6-7k rpm.
