XT: quiet exhaust upgrades?

Its going to be hard to say. Remember CVT + 2.0 motor = not loud car.

So once we figure out a downpipe options they do get louder. I haven't compared a n/a car to xt, since 6mt sound natrually louder already.

Someone put on a q300. I think a few people said the sti exhaust isn't loud at all it almost isn't noticable when cruising, slight drone in the low end.

I was hoping you'd reply since it seems you've done some of the most work on the XT. I like your N1 a lot, can you hear it in the cabin?

Since the CVT spends so much time in the low end, droning down low could get pretty annoying quick. I have a line on a cheap stock 2011 STI midpipe and exhaust, wondering if it'd improve anything at all flow wise compared to stock?

I'm not sure about the airflow, I think its more noise. But most guys said it quiet down pretty quick. The trick about the cvt is just left off the gas and keep it at a different tone.

My cabin noise is noticeable nothing to bother too many people. There is a slight drone in cruising but I just adjust the throttle if it bothers me.

2011 STi i think there is a clip or two in one of the two exhaust threads.

I have the catback off a 2013 STi on mine. I did this for looks. It doesn't really increase airflow or power gains. If you want power gains look at the Nameless CBE systems.

So with the STi system noise wise is pretty much stock. At start up it has a very nice low rumble. Then between 1-1.5k rpms, there's a slight drone/rumble. This drone though to me is minor. I actually like it. Highway speeds it sounds like stock. Keep in mind you will need to trim your lower bumper area to accommodate the quad tips and there's fabrication needed from muffler to ypipe. If you want to read my full review on experience with pics check out my thread. It's on page pg 10. post #138.

Wow, that's perfect, exactly what I wanted to know thanks! So the FXT midpipe was narrower only after the resonator? Was the muffler diameter the larger size or the smaller size? Wondering if it's possible to just change the midpipe then to make the exhaust the same diameter all the way through?

Was it difficult to do the cutting? Are there any single tip options that would fit better?

Stock wrx exhaust. You could just have a muffler shop cut out the resonator and add straight piping.

That won't be a quiet exhaust upgrade though.^

No problem man. Yeah the FXT midpipe after resonator was much smaller than STi. Hmmm, trying to visualize what you mean but I can't. Any shop could easily fabricate what I had done with mine though. As for cutting, it was pretty easy going. Like what lcrazy mentioned, the wrx exhaust but making it straight pipe could get loud. Look at the Nameless muffler upgrade. They made one specifically for ours and it sounds pretty good. Kinda pricey but they are well known for their quality work. Danpo on here posted a vid of the nameless muffler upgrade then he went with full CBE exhaust shortly after. It sounds really good. I just heard it in person last weekend. He also posted vids of that on here as well. Eventually I would want a quad set up from Nameless, they have proven better air flow with their set ups which leads to slight increase in power....low and high end.

Thanks for all the input you guys Think I have to do some additional research.

I have the invidia q300 system on mine and in my option it's money. It is exactly what I was looking for, especially now that it is broken in. It's got a nice purr to it and solid clean sound when you hit it. Nothing crazy ricey or anything. Honestly it is what our turbos should sound like. Also no drone either

I should mention that the wife thinks it sounds right and she is the biggest critic. In other words she thought the wrx exhaust on my '12 NA forester was annoying and too loud.

Yes if you could get more info please. The more options available we have the better. Those STI axle-back mufflers are way too much money from Japan Parts lol..

If you want it quiet just keep it stock

Stock looks boring though. lol

My STi pipes sound like stock 90% of the time and has the cool look factor. Just sayin. =)

COBB in Socal are selling tons of used Stock WRX Sti Catback qaud tip exhaust. They told me $30 if picked up.

Sway and I have the same set up, only difference is i am still using the stock xt midpipe. Love em... Went for Cosmetic/looks Purpose only.

I am probably going Perrin resonated.

What we don't have a great sense of is how sound is going to change once we add a high-flow or cat less j-pipe.

There is a big exhaust thread for the 2015 wrx over on nasioc with lots of pics and sound clips, check it out.
