Ok, it thoses are my choices greddy. I would go with that cat-back becuase it is not as loud as the N1 and you are going to get the same gains. If I were you and I was worried about emission and stuff I would save alittle more and get a highflow downpipe with the cat back you will get more power. look on the vender pages there are a bunch of good deals. Also, check out http://www.jscspeed.com andhttp://www.gruppe-s.com they always have some good deals running.

If you want more information on the right exhust system for you are going to have to give out some more information about what your plans are and what you want out of your car.

Personally, I have HKS carbon Ti (for the ladies), helix uppipe and downpipe. BUt it is carzy load at WOT with no cats. (I am running stage four)

 

I would go for HKS, yes it's loud, but it's very nice!

 

i have the Helix cat-back and i really love, also look in the "review" section and look at the cat-backs there that should also help.

 

If those were my 2 choices, I'd have to get the Greddy. Only because, to me at least, the sound of the Greddy isn't overly loud. I hear it makes good power too. I like the stealth look of my Vishnu though.

 

Greddy Evo. It's 3" piping vs 2.5" for the N1. Plus it sounds great.

 

neither have cats....these are catback exhausts right? they dont even touch the cats in the downpipe and midpipe.

 

Out of the two, i'd take the greddy. There are better options out there though. I'd recommend researching more about it before you finally make your decision. Exhausts are pretty expensive, and you might regret buying one, and then finding another one you like better afterwards.

 

BORLA HUSH!!!

 

 

If you specifically mean the Apex'i N1, then I recommend against it. Go for the Greddy, it's a good combination of power and soft sound.
If I were to recommend a catback though, I'd suggest either the HKS Hi-Power or the Blitz Nur-Spec. The HKS is slightly quieter and makes very high torque, while the Blitz is super-loud but makes excellent horsepower.
