Update:
If you want a true 80mm Magnaflow Ti catback, buy the non-resonated version. The 2" reducer inside the resonator DOES NOT come out. Despite only seeing spot welds, it appears to have been welded around the perimeter as an integral part of the resonator. I will be returning mine for a non-resonated version. I can't understand how a manufacturer such as Magnaflow would take the time, expertise, and materials to produce a titanium exhaust with this anomaly inside it. I have been just shaking my head for the past 12 hours.

Heres some pics, mine just got dropped off and i want to let everyone see what were talking about. To me it does not look to be an intergral part of the resonator so far, not on mine anyways, i only see the spot welds shown, that you can see on both the inlet side and outlet side. If and when i ever do get a bigger downpipe, ill probably gut that piece of of the pipe, but for now, it will probably help me keep my exhaust note below the radar.

Inlet side... (2 pics)





Outlet side... (1 pic)




I have to disagree on this being an "anomaly", I think from the way its designed, that its meant to be there and its not misleading to advertise the exhaust as 80mm piping, because it is. There just happens to be a resonater assembly in line on the exhaust. Theres still the bottleneck at the dowpipe flange anyways, so your never going to have a true 3"/80mm flowthru from the turbo back with this kit unless you do some modifying at the flange anyways.


EDIT: Go figure something would go wrong. I dont seem to have teh donut gasket in the box, ive been thru everything twice to be sure and its not there. Will I be able to re-use the stock gasket since im using the stock downpipe for now?

EDIT2: Nevermind, just installed it without the gasket, ill buy one early next week and re-install the flange portion with a fresh gasket.

Ok, new post to not confuse, its now 1:30 and about 2 hours later, I have installed the exhaust, tucked the old one away in the garage for safekeeping, taken my "after" videos of the car idleing and revving (take-offs and drive-bys will be later, sorry no stock comparison thou) and did a mini photo shoot to get some initial images before the exhaust gets el-durty.

Couldnt find that gasket and realized it doesnt look like there is one on the stock exhaust, but the flanges bolted up nice and tight and it appears to be sealed good enough until i can get a gasket later. I think i have it all aligned properly and i have about 3/8" - 1/2" of clearance between the exhaust tip and bumper. I hope thats enough to not melt.

Initial impressions with both resonator and silencer in was, "Wow, did i do 2 hours of work for nothing?" It literally sounds no louder than stock. Once the engine settled in it became apparent that there was now a low grumble coming from the back of the car that is non-existent with the stock exhaust. Very nice, since that wont be attracting much more attention, if any. On revving the car, i get a nice little purr and then some raspyness, im concerned... Keep revving, different rpm's, with a final sweep to 5k before idling down and shutting off the engine.

Now the real test, the silencer. Took that bad boy out. Side note: with a little black paint you wont even know its there under anything short of direct sunlight, its tucked WAY back in the tip almost into the muffler itself. Fire it up, and SPLOOGE! The car now sounds like an awoken beast. Revving, i can hear the growl and can definitely tell that the turbo is spooling at least somewhat easier in idle than it would with the stock exhaust... But still, i got a little raspyness at certain rpms, and cant figure out why... All i know is that i LOVE the sound, best exhaust note ive ever heard, I love it even more than my old 350z exhaust. Give it a sweep to 5k and its just growls all the way there, and then i got the distinct crackle popping as it idled down, just absolutely amazing.

Finally sit down outside the car and look the line up and down, trying to find out where that raspy noise was coming from. Finally i realize that its the springs they provide to hold the muffler to the mid pipe of the kit, Why they provided them, i dont know, whit i put them on, cause the instructions said to. Normally im not an instruction kinda guy, but in this case, it was 3 steps long on paper. Took the springs back off, fired it up, revved it up, and NO RASPYNESS anymore. I suggest just making sure the muffler is on tight and leave the springs out. If you want the extra security, you can use the thin aircraft cable and cable crimps provided in place of the springs, ill do that later when i get a crimping plier.

All said and done, it was money well spent for what i wanted to achieve. Looks, sound, and a little performance improvement to keep me happy that my cars not stock anymore... If you really want ALL performance you can from the exhaust or drive an STi, get the non-resonated version, if you have a WRX and drive it daily to work, go for the resonated one. Im sure the restrictor in the resonator is only 10 minutes with a dremel away from not being a problem anymore....

So, now whos going to help me convert these before/after clips down to size so i can share them with you all?

It looks like they used a 2" inlet resonator...glad it sounds good. Now i'm curious how the non resonated one sounds on an STi.

The resonator itself is 80mm inside, that 2" pipe is welded at the "outlet" side of the resonator, and the pipe extends about 4-5 inches into the resonator back towards the front of the car. If that makes sence.

G3Red04WRX: You stated above: "I have to disagree on this being an "anomaly", I think from the way its designed, that its meant to be there and its not misleading to advertise the exhaust as 80mm piping, because it is."

I called Magnaflow direct and they even admitted that it was a restriction and they don't even recommend the resonated Titanium version for the STi. How's that make you feel that the manufacturer that sold you that exhaust admitted this little fact! I don't care what anyone else does with their car and how they modify it; I always do it right the first time.

Don't get so pissed off at me that you bought the wrong exhaust. Its right on Magnaflow's website that the resonated version is intended for the WRX only. Maybe they admitted its a "restriction", but did they ever say it was a mistake on their part to put that piece in there? The resonator itself is still the same size as the rest of the exhaust line, you just have that extra piece in there to help quiet things down. Dont want that piece in there, then cut it out of there, but in that case you might as well just have gotten the non-resonated version since its beating the purpose of the resonator being there.

I still feel great about my purchase, and see no reason to be upset they admitted the fact its a restriction. At least they didnt try to lie about it. Could have told the public about the restriction in the resonated version, yes, but it still wouldnt have changed my mind about the purchase.

If you really were to "do it right the first time" you should have done a little more research and just gotten a full turbo-back exhaust that has absolutely NO restrictions ANYWHERE from the dump-down to the muffler tip. Your gonna be screwed anyway you look at it if you bought the magnaflow Ti since your always going to have the restriction at the flange that bolts to your downpipe. So in this case it appears you DONT always do it right, and now your just being an ass about it because YOU made the mistake.

Return the magnaflow, drop a couple hundred extra bucks into a full turboback, and stop complaining about one little thing you didnt like. Maybe have a beer too or something and ligthen up, after all, its just a car part.

I didn't make a mistake. I made SEVERAL inquiries to Magnaflow, the Nasioc forum, and the vendor I bought it from and nothing was mentioned about this. Just FYI, I'm running a catless stock downpipe so the flange is fine with me. Why am I running a stock catless downpipe? Because it's free and it's part of the $40 in mods I have done to my car and I run 12s with it. There are Stage 2 people that are still running 13s. Less is more, and I can prove it. Just come to Englishtown, NJ tomorrow if that's possible for you. Look for a 2004 White STi with a dent in the rear bumper.

I enjoy a nice cold beer once in a while.

Price is now fixed at $710 shipped, available for ordering via the website!

You can mate this to the stock dp, or the helix as well

Not a whole lot left so get them while you can!
