A muffler isn't a bottleneck in the system, you have two or three cats that are designed to essentially choke flow, you can make the exit as big as you want but if the gases can't flow through the cats any faster, you're wasting your money. It's like having a gigantic stomach but a tiny mouth.
looking at the INJEN upgrade exhaust which is a full cat, I couldnt really see a massive gain from that. then again i am willing to admit, things are different when it comes to the PZEV, off the top of my head I think the exhaust made 10 whp based on the 143hp spec.
Since our engines are not really geared for HP but more towards TQ points, back pressure is a good thing
getting back to the subject we were talking about.... you are right that , the hp vs. dolllar doesnt sometimes make sense when buying bolt ons. I think we all buythese things cause we actually feel like we are building something with our own hands. instead of standing back, tune tune and presto.
I only wish getting tuning done here was cheaper in Canada. I almost rolled over when FourStar told me their standard rates for EVO tuning. :O
I would say that the Cat + resonator are less restrictive than the muffer, i have Cutted our muffler it is, one of the worst molesters or flow that I have ever seen. compared to other ones I have looked inside of.

I highly doubt the exhaust made 10 whp on a 143 HP motor. Never trust company dynos, they're usually full of ****.

we are about the put AEM and INJENs claims to the test in a Dyno Day in terms of the intakes, plus one mystery intake. An exhaust show down is set for the summer.

rrm SRI/Pulley
My wife bought a 09 lancer de and had the rrm sri and pulley installed by in august of 08. I just bought a 09 lancer de (same as my wife) and decided to test it out to see if there was a difference. At the light, when she floored it, 2 seconds into the run, her front bumper was already 2ft in front, by 5 seconds she was a whole car length in front.
We're going to pull the sri so that she can get warranty defect fixed at local mitsubishi. I'm going to race her again with just the pulley and see which one is making the difference.
I'm thinking about getting the rrm timing mod, and racing that against my wife's sri and pulley to see if we are a match from light to light.

The funny thing is, i didn't think it would make that much of a difference. Now I have to study your youtube video to take off the sri so that she can get the break recall fixed at a local dealer, then put it back on. Unless you know of a local dealer that will...hmmm...ignore the sri and do the work. Did you say at one time Norco mitsu is friendly to modders? I'd rather not take the chance of hosing her warranty.

that sounds like you have defective car. with an SRI and pully theres no way shes gonna be a full car ahead of you.
You will not have a warranty issue with Norco if you have RRM stuff. I am quite sure of it. IF you do call us asap. We will smooth it out but I expect we will never have to once you say the parts are ROAD/RACE.
