I have the Apexi N1 duals on my car. Be prepared to spend some coin to get them up here, I paid the better part of $1400CDN for mine, the Racingbeat wont be cheap either, if memory serves, someone up here said $1800 for the whole deal including downpipe and presilencer.

The N1's are a bit loud, and they do drone, but it's not all that bad, I have not had any real trouble with the police about them (knock on wood) if you drive the car civilized you can keep the tone down, once you get on boost they get pretty loud. I'm not sure how well the silencers work I don't have them, I have seen them on a third gen and I would think the increased back pressure might take away some performance, plus at $40USD a pop they're a bit expensive.

 

turbo2:
Did you buy just two n1 mufflers and then got a shop to install them or did you buy the system? if you baught the system how much of that was shipping? cause i work at a car dealer which will install the stuff pretty cheap like REAL cheap! so i am currious if two N1 Mufflers and a 3inch dp and then from there back 3inch madrel bent pipe to the y then 2.5 inch to the two N1's? is this similar to what you have or not?
And what do the rest of you think about this?

 

I dont know what kind of exhaust this is, but I really like the tips. Anyone have any idea??

 

here is my rear end and my current exhaust is stock with gutted cats! however the tips are aftermarket! here is a pic!
