Default what is the best cat-back exhaust out there??

Ok, now that I have done some research about the various exhausts out there for subies, I have made some conclusions.

1.) I live in PA where there is decent amounts of snow i.e. there is crap on the ground to get rid of snow and corrode my exhaust.

2.) MRT has the best design/price but is made of mild steel so it will be corroded in a matter of time.

-so if I just wanted to put together my exhaust, what manufacturers should I be looking at?

-is Borla's new header an improvement??
-is stromungs midpipe and muffler worth the big buck??
-what is a good cat-back to bolt up?
-this is my second mod besides a Cobb CAI
-which if any will trip a CEL? (don't want to see the CEL go off unless I stall out. . haha)

Thanks to all the i-clubbers out there

Go used to avoid the big bucks.

I saw 2 stomungs - (one of them new), 2 STi exhausts and 1 prodrive exhausts FS on the various forums.

These should work well and are all high quality.

Should we do the "use a search" thing since there are tons of cat-back threads?

Since you live in snow areas, definately get stainless steel. The others will definately rust out.

Stromung makes a stainless steel and so is Cobb's. You can find tons of information on those two plus others in here.

I've always really liked all of Brullen's stainless products, and installed a few of their products myself. Quality is excellent, gains are good, and the sound is... amazing.

Do a search for posts from GTBGUY concerning their(iON Performance) products, or PM him to learn more.

I agree, but.. Pot. Kettle. Black.

I'm a Brullen guy. I'll tell you to get a Brullen until I'm blue. Not cheap, but quality. If you can't swing the bucks, then used is prolly a good way to go. Stromungs are muffler only -- if you want a cat back, you'll save no $$ over a Brullen system.

OK...I'll play nice...

Your header choices (as of right now...and the "normal" priced ones) are
MRT
Brullen
Borla

MRT and Brullen will replace the cat section as well. I believe MRT has the better design. Brullen is the newest kid on the block. Borla will replace the header only leaving the stock cats in place.

Midpipe (post cats to can)... Several exhaust companies sell a midpipe. Stromong, Brullen (I think...) perhaps some of the others do. The stock midpipe isn't terrible...but it could stand to be wider and with a replacement you have the choice of having a resonator or not. The resonator will have little effect on power, but will have a larger effect on sound.

Exhaust cans...millions of choices...seriously. Power output will be generally the same on all...the only "real" diffences will be with build quality, fitment on the car, looks, and sound.

Now to answer your questions...

Q: so if I just wanted to put together my exhaust, what manufacturers should I be looking at?
A: Well since you are in an area that has corrosion problems, I'd go with a stainless steel setup. MRT is mild steel but can be treated so it won't rust. The Borla header is stainless and has a great guarantee. Stromong makes a stainless midpipe and can...but there have been problems with rust. I'd go with whichever company will give you a guarantee while taking my above comments into mind.

Q: is Borla's new header an improvement??
A: Improvement over what? If you mean stock...yes it is without a doubt. You won't get the power gains you'd get from a full MRT setup (vs. Borla header, midpipe and can) but you will get fantastic sound...and an American company with a guarantee that'll be easier to deal with

Q: is stromungs midpipe and muffler worth the big buck??
A: Historically this has been the most popular. However you might run into problems living in the snow belt. I'd contact a vendor who sells it and get warranty info. For more info, search.

Q: what is a good cat-back to bolt up?
A: Well...that depends on what you are looking for. See above info.

Q: this is my second mod besides a Cobb CAI
A: Oops...not a question, I just got into a groove. Intake, header and exhaust are the most common N/A basic improvements. I HIGHLY suggest comming up with a "goal" in mind for the car they tailoring your mods around that goal. That way you can pick items that will compliment each other (and the purpose of the car) well, and you'll know exactly what to look for. It will save you from buying something and eventually replacing it too.

Q: which if any will trip a CEL? (don't want to see the CEL go off unless I stall out. . haha)
A: That's tough to say. I've thrown a CE light from all kinds of things...all kinds of combinations. If you are really concerned about it get an OBD-II scanner...that will allow you to read the code and diagnose from home. I don't think there is a definitive answer out there to why different exhausts throw 'da light...but there have been sucesses with heat insulation.

FYI my exhauts have been...
Stock
Borla midpipe and can
Borla header, midpipe and can (occasional rare CE...no biggie, no effect on performance)
MRT header, cat, midpipe with Borla can (CE light pretty soon after putting it on...but much better power than prior set up)

Any more questions?

thanks for the help guys. . . seems like only a full MRT setup will really trip the CEL, but that is where the biggest gains are to be had. As for the borla headers, I was referring back to their old design which seemed to crack or produce other problems. They said they corrected those issues in their new design but I wanted to see if anyone had more info on that. Thanks again to everyone who replied.

my basic plans for my subie
-make it a bit faster first (intake, exhaust, chip?, cams?)
-make it handle better second (larger rear sway bar, possibly coil overs?, tires?, brakes?)
-no plans ever for a turbo or s/c (I'm graduating in a year and gonna be able to buy sth really fast)

anyways, thanks for the replies guys (even to those who just said "do a search")

If you're gonna get another car in a year, why don't you save the money and just get some handling mods! Some tires, rims, sway bars, springs/shocks/struts/etc ... that way when you get the STi or WRX or whichever, you already have all that stuff!

And personally, making your car handle better, especially our RS's makes the car sooo much fun! I did the handling upgrades first since while not amazingly fast, I felt the weak point of our cars is the handling.

Just my $0.02 of course
