I have the Invidia N1 system and i love it, it sounds like a GT car. now the choices.

1. Keep the N1
2. Buy HKS td and add test pipes.
3. Keep the N1 and add resonated test pipes, and the Mrev lower.

Thank you. Any information about what these combos will sound like let me know. I love a high pitched scream. as close as i can get to a ferrari sound.

 

ill go with #3 some tp and rev up..sound will change on your exhaust and you may like it...you still need some tp and mrev so you ahve nothn to lose...i got the topspeed tp and topspeed exhaust that $H!T is LOUD does not sound V6 and it guggles like crazzzzzzzy when shifting and when i heel toe... o ya beware may be raspy and may raddle like mine but i have a stock y thats y theres a lil raddle cause of it but soon to have the topspeed y to install this weekend...hope the raddel stops

I'd say #3. are you FI? isn't TD usually only worth it if you're FI?

 

#3 will net a lot more gains.

Install that on the dyno and you will feel real good about your decision!

 

yeah i have a rattle but i think it is just the interior panels. I am not FI. will the resonated test pipes make the invidia N1 unlivable. i do have the removable scilencers, i have not tried them though

 

my rattle is from the piping and it sounds tough tho i say do it if not you can always try your silencers or even sell them if you dont like them im gettin use to mine but gettin really pisst on that rattle waitin on my y to get here soon

 

Personally i dont like teh HKS exhaust. It sounds pretty ricey, even though its got the 'name'. I think you should check out the Fast intensions exhaust. Its summing up to be one of the best exhausts for the 350Z/G35. Its very popular with the G's. With test pipes, itll be just a little loud and have NO rasp. HKS with test pipes will be pretty raspy because it lacks an X pipe.
