Midpipe
Has any one here changed their midpipe? Someone mentioned before that the N1 midpipe sounded ricey. What is wrong with just putting on a standard bigger pipe? I was thinking about a glass pack with a 2.25 diameter, but then i'm afraid that will make it too quiet. Any suggestions? Other wise I don't see what is wrong with just a standard pipe which is like 10 bucks in parts. I've heard a 4cyl Jeeps with bigger pipes that sound nice, but they also have a different engine architecture.

I had a local shop order a 10 foot stick of 2.5 inch stainless steel and then bend me a custom pipe. To be legal I had the shop integrate one of the most freeflowing cats out there, a Northstar cat. With Borla Headers and cat back piece, the exhaust sounds great and breathes effortlessly. I suggest you talk with reputable local shop.

I have Borla Headers, no cats (yes I'm evil), with a 2.25"glass pack in the stromung 2.25" midpipe and the stromung dual tip SS muffler. The car sounds great. Not ricey one bit.
here's a clip. It was a little too close to the exhaust pipe when I revved it so it distorted just a little bit. However you get the idea especially when you listen to the idle.

Major exhaust components:
headers/manifolds
resonators
mufflers
Catalytic convertors
pipes: midpipe, tailpipe etc
A glass pack is a kind of muffler. Often called "cherry bombs". They are basically a pipe with a bunch of holes in it, wrapped in fiberglass enclosed in a bigger pipe. They act similar to a resonator.
They are a straight shot for exhaust to travel-very low restriction and just remove the high notes in the exhaust. Without the glass pack or catalytic convertor the exhaust is very "pipey" or "ricey"

i just had minekee add a 2.25 custom midpipe to my scoobysport axleback. I drive an 02rs. im not sure about you guys but there is no cat in the midpipe. from the outside it sure looks like a cat, the mechanics wouldnt touch it. and were mocking me. They said "were going to have to charge you 20 bucks to take that thing down and tell you its a cat. We know what were talking about and that is most certainly a cat so you might as well save yourself 20 dollars" i was like just take it down and look in it. needless to say they came back 5 minutes later and were like "what diameter piping did you say you wanted again?" i just laughed.
but i did not have them add any resonators into the system. I wouldnt say that the car got much louder. maybe a little fuller sounding. and a little more of that warble/crackle subaru sound that we all love. but not obnoxious. definate increase in performance.

You are right.
There isn't a cat in the mid pipe.
There are four sections on our cars.
Headers/Manifold
Cat section
mid pipe
tailpipe.
My cat section is replaced with a 2.5" pipe that is reduced down to 2.25 at the glasspack.

I only went 2.5 after the headers because it WASN'T mandrel bent. It is reduced to 2.25 at the cherry bomb. The 2.25 is mandrel bent. So I don't think the flow is much different between the two.
