I am interested in both the gtspec and the N1 single. Does anyone have either of them? If so how do u like it? good sound? power gain?

 

Sorry. I have a Corksport catback. If someone posts a Apex sound clip you can compair it to this: http://ca.geocities.com/nosaj13b/CorkSport.mp3

 

^^ rockin' the phone dials like me!

do you have a header and presilencer with that corksport exhaust??

im going to get that cat back and the RB header and presilencer.

 

Phone Dials For Life! hahaha. Im running just the catback right now. I do hope to pick up a RB header and presilencer very soon.

 

I haven't heard alot about the GTSpec but nothing but good things coming from the N1. A few people on this forum are pushing 400hp without any restriction using the N1. Phil Garrots site also listed that the power gains from a N1 catback were quit impressive (he had it with a RB header and presilencer). But usually catbacks are for sound, full exhausts are for power (you will receive gains from both, but more noticable gains will come from using a header/presilcer or a downpipe/presilencer depending on your application).
