The new design angles the muffler downwards to meet up with the piping. This seems to create the straightest flow path possible. I liked this aspect of the design, even though I don't think it really helped ground clearance that much. I think this must be what makes the exhaust somewhat loud, IMO.

Of course sound is all subjective, I have heard many exhausts that are louder. The Q300 is actually very quiet at idle, but the noise while cruising is what really got to me.

Yes, mine is the newer design as well. It looks like the muffler is on a 45 degree angle. Luckily I haven't had any issues scraping it yet!

As you said, sound is subjective so maybe that's the difference. I did have an Invidia N1 before the q300 so....

It has been proven on dynos that the catbacks do basically nothing for our cars outside of sound and looks.

BTW...my plans just got finished today...I'm coming for you...

Read the about the FMS FMIC but now that you have more miles on the set up how's it holding up? How's driving in traffic and normal city stuff? Major change in driving or not really? Throttle response slightly less like everyone rumors about true? I'm really debating getting a FMIC or PW TMIC. I love all the advantages about the FMIC though and the ability to have room for upgrades in the future. The only crappy thing is i spent $290 on the Cobb intake that i don't think will work with any FMIC.

1.5 = Dom1.5 XTR?

That's a great choice. I really like the specs on that one. Very similar to what I have, but with a hair more output.

I still like it. The black powdercoating really didn't hold up that well, but it doesn't seem to have gotten too much worse recently. You can't see it from more than 10ft away, but up close it's getting pretty chipped up. Install was a pain, but other than that it seems like a decent kit.

Change in spool is not really even noticeable on the road. If you do a dyno plot, maybe there's a difference, but it's not something I picked up on while driving. The PW TMIC seems like a really nice kit. Install would be much more straightforward, but the FMIC has it's advantages too.

Hi Xluben, itís very fortunate for me find your build thread. your reviews are very accurate and detailed. Iíve gain many valuable knowledge through reading it, Iím waiting on my 12 WRX hatch limited in SWP w/ SPT, been a month and still no news. Maybe itís the color and/or the edition, reading your thread is making it tough for me LOL.

Car is going to be 100% DD in nor Cal with occasional driving to snowboarding, campingÖ

Goal is to maximize the carís potential with practical mods

Please help with some questions I have left,
- Sways, based on your experience seems like 22mm Front and Rear is doing exactly how I would want my car to. Any improvement over that on the 24mm front?
- Stage 1, doesnít seem like Iíll need AP so probably use that money towards the custom tune with COBB intake and stay with this mod for awhile. Would you think this is a proper step? Anything I should consider for keeping the car running smooth and strong?
- Brakes, how are they for stock? If need to change, would pads, brake lines and fluid improve greatly? I see you installed the cylinder brace and is that a good investment?
- H&R 25mm spacers, how are they so far and any issues? Any downside? <<< I know, itís not a practical mod but it looks soÖ. Good~!
Thanks for your answers in advance

PS Ė thereís this 11 WRX hatch in SWP crossing the intersection on my way home every day that I look forward to seeing it, and days that I donít I feel a bit dissappointed. I may have issues~!

Hello alexxo. I am glad my thread has helped you. May I suggest you fill out your profile with your vehicle and location? It will generally help give responses to your questions. My car is also a daily driver, and I have tried to stick with the most practical mods that I can. Here are some attempts at answering you questions.

Sways - I went with 22f/22r sways because I wanted a bit more of a balanced setup. I did run the 24f sway for a while, and I thought they both felt good, but it seems a little more neutral with the even sway bar sizes. I would also recommend upgrading endlinks when you do the sway bar. If you don't they will still flex and you will not be as stiff as you should be.
Stage 1 - A custom tune is a great thing to do to keep the car running well. If you're getting a custom tune, I would put on as many parts as you plan on getting before the tune (to save money on re-tunes). The intake is not entirely necessary, but it does sound cool and helps flow a bit. I would consider going Stage 2 if you want a little more power. I think the $/hp is worth it.
Brakes - I am still on the stock pads, lines and fluid. I plan on changing that all out before next summer. The stock setup works fine for the street, but falls short on the track. I had braking problems after every few laps on the road course. On the street it is 100% adequate. The brace helps make the pedal feel more consistent. It is worth it if you are doing track/autocross.
Spacers - I have not had any issues so far. But they will increase stress on the wheel bearings. This is unavoidable. The same would happen with wider, or lower offset wheels. I am aware of this, and will to accept it. If you get good quality spacers you should be OK other than the increased wear.

-Ben

Thanks for the quick response~! will update my profile once I take the car home.

Any preference on which end links? Whiteline, Perrin, RallitekÖ

Yeah the Intake is probably not a great idea, COBB seems have a very loud.. well.. sucking noise, I donít mind it during WOT. But from the way users described, I know the GF is gonna start complaining during DD and especially longer trips. Planning to get marry soon so happy wife happy life right? lol
Probably have to read some more, AEM seems quiet but itís hard to determine base on sound clips

Stage 2 worries me a bit, not sure how soon will I see related issues with the car even with normal driving. Hard to collect this type of information because most pplz wonít stay at just DP + intake and re-tune.

Iím not a DIY type of guy, found out that the hard way with my turboíed Honda prelude couple cars ago, probably thought I can turn it into a 911 or somethingÖ man that was a mess, all kinds of trouble and getting pulled over left and right for the rice mods. Spent more time fixing, modding and worrying than enjoy driving.

So sways 22/22, endlinks, stage 1 tune and yes spacers are confirmed~!

i have a cobb intake. if sounds great when you are in the mood to hear it, it sounds awful when you are trying to climb a mountain or just lazily pass someone on the highway. No where near as annoying as a droning exhaust though. I have mixed feelings about it.

probably the wrong thread to discuss this in though

that's very good info and enough for me to know for SURE it's not what I want. I worry the same for the SPT exhaust, only one way to find out now...

I have the Rallitek endlinks. They are a stronger version of the OEM-style endlinks. The intake really isn't too bad but it can be noticeable. If you're not trying to make it sound cooler/louder, then I would probably skip it. I agree that a droning exhaust is much worse. The SPT has really well controlled drone though. I would consider it if you must have a cat back. If you just want the power and not the noise, I would definitely go for a downipe and Stage 2 tune.

Going Stage 2 with a stock intake and catback is really not going to change how the car looks or sounds at all. It will basically seem totally stock, and have up to 50HP more (with a custom tune). Sway bars are nice for adding a little stiffness to the ride. Most people enjoy them. Spacers are 100% for looks only (in this case), and are a more controversial mod. But if you really don't want to go Stage 2, I think you'll be happy with Stage 1 as well.

Ralitek Endlinks it is…

For sure I don’t want it to sound like a drag car while pushing only 250whp especially in my area where the cops have very little things to deal with. The car itself is already loud as it is in sound and visual. Glad to once again confirmed that the SPT exhaust have a well balanced note

You’re like the devil~! think that will prioritze over reliability at this point given that I plan to go for something else in around 4-5 years , looks like stage 2 it is after breaking in LOL

Wow, 13 minutes of dyno pulls. I would never watch that. Skipped to 4 minutes and saw a sedan. The sedan and hatch sound COMPLETELY different, even with the same brand/model of exhaust.

The hatch is a lot quieter than the sedan no matter what. My car is pretty much silent when cruising around.

I wonder how much power would be given up on a sedan if you got a protune with a downpipe, process west tmic, ebcs but kept the stock intake and cat back.

The older I get the more I want a stealth set up.
