I have been looking into it a lot and have seen a few things about it but nothing certain.

I've decided to go with Mazzuri and was pretty set on the newer 2.5" system but now I'm starting to wonder...

One thing I saw was that the older 3" system wasn't really needed unless you go turbo otherwise you wouldn't utalize the extra space in the pipes.. I have also seen that the 3" full lost gains because of the cat or muffler or whatever it was on it.

The 2.5" system that is just the Header and Y-Pipe is what I have really been looking at now and my plan was just to maybe add a nice muffler to the stock B-Pipe and throw on an after market Exhaust.

What would end up getting the best gains for a simple N/A system?

The full 3" system or the 2.5" Header, Y system with an after market Exhaust?

The newer 2.5" is enough flow for our NA engine. You may gain a few horsepower with the 3" system but I doubt it is very noticeable, plus every comment about the 3" system is that is LOUD. hah, yes most users put the loud in caps when they posted about it.

Yes, simple logic/doing your homework seems to evade alot of people on this site.

The mazzuri SRS or newer header/y combo will not work with a turbo... as it is not a turbo manifold.

I'm selling my SRS system. :O)

I was simply saying that I heard you wouldn't need the 3" with simple n/a. I realize its not a turbo system.

My question, which I could have worded better, is do you need the 3" or is the 2.5" more than enough flow.

Read my first post, 2.5" is enough for our little 3.0L engine.
