I was under the impression that he was wanting to keep the cat. Must have misread his post. I mainly suggested the GT-Spec cause of it being full stainless and Gruppe-S having a sale on them.

Oh well, I'm satisfied with my exhaust. It is louder than my old HKS Carbon-Ti, but I actually prefer the sound of the GT-Spec over the HKS. I'm assuming the N-1 probably sounds about what the HKS does.

When it comes down to it all exhaust are going to sound different on different cars!

The cams and 02 dump made the difference between his and the others'.

I had an Apexi N1 exhaust, and it was only slightly louder than stock. Most people weren't even aware I had an aftermarket exhaust. I also had a stock cat. I'm currently running an Espelir catless and it's significantly louder.

I also have an N1 and like someone mentioned it is a very tame exhaust, none of that raspy sound at WOT.

. Since then I have changed my setup as you see in my sig. I think all the port work I have done on the exhaust side and the larger o2 dump plays a role in the new tone to the exhaust. I will try and see if I can take some video tomorrow of my new lower idle when I get to work

Im planning to go BBK-Full, therefore GSC S2s are my best bet!!

I was thinking of Getting MAP's O2 Eliminator dump but BLKCarbonEVO said that its not that good, so, I have no idea what setup will be the best!!!!

I think this is going to be my setup, so let me know what you guys think is going to happen sound-wise:

Apexi N1
GSC S2
Invidia Cat-delete (bought it already)
Map O2 Eliminator dump(unless you people suggest a replacement)
Stock, un-ported exhaust manifold..

OR do the same setup but replace the N1 with the HKS hi power "silent"!!!

Here is the video, i dont think that he has more mods

Let me know ur predictions after joining this exhaust with the remaining mods!!

The o2 dump eliminator I have heard of people having problems with them but the MAPerformance External Dump O2 Housing I know for a fact on a proper setup will pick up 30-50hp depending on the setup.....before I get flammed I have seen it for my own eyes

If you want to stay with MAP get the External dump 02 housing. Not the eliminater.

You can try this: http://www.maperformance.com/map-sta...s-mvs-evo.html I know a local guy to my area who will be using it on his FP Black setup.

Or you can this http://www.maperformance.com/maperfo...2h-ss-evo.html and a traditional DP

So This should be my setup:

Apexi N1
External dump 02 housing
Invidia cat-delete
Downpipe (what type is best??)

But this dump is 2.5"!!! Let me know what you guys think!

Most DP's work great...as long as it 3" in diam then your good. As for the diam of the 02 dump most are about 2.5" But like I posted before the external dump works well. It was done on a FP red built block and head, 93oct 28psi.

Can't comment on it I have no experience with it. I know my EPM o2 dump and the MAP. In hindsight if I could go back and do it again I would get the MAP one much better piece but I couldn't complain about it works great so nothing to stress about.
