Invidia Dual N1 Titanium burnt tips Catback Exhaust | 2015-Up Subaru WRX STI (HS15STIGTT)

Paired this system on my 17 WRX with a catted downpipe and a stage 2 tune. First off, this system sounds amazing. I was concerned with the highway 'drone or buzz' and was hesitant to purchase an exhaust. Have no fear, you can barely notice the sound when you're just cruising. Get on it a little bit, you get a very pleasant and deep rumble as you accelerate. Get on it alot, and once the turbo kicks in with the pedal down the sound is pure ecstasy and can make you pee a little the first time you hear it. If it would have sounded like a typical 4 banger screaming exhaust, I would have taken it off and thrown it in the dumpster. The vehicle sounds like a pure racing engine, and is downright intimidating to Mustang GTs and similar V8s (i hate mustangs sorry). It can also have a nice pop when shifting gears at high rpms.

It does make quite a bit of noise for the first 30 seconds following a cold start, but once the car begins idling down it isn't too much. I would recommend this set-up to anyone wanting to make some good noise, and no, it does not sound like any of the cliche names given to most 4 cylinders with exhaust systems. One note, it comes with a spacer for the rear O2 sensor. In my case, installing the spacer resulted in the check engine light coming on intermittently for a low voltage error. Removing the spacer did the trick, and I haven't had problems yet.

The only problem you prospective buyers will have is choosing the 4 tips or the 2 canon setup I picked. Great job all around, and MAP even worked with me on shipping so I could get it a couple days quicker.

Let me start by saying that there are no downsides to this exhaust and that it is AMAZING, and not just for the price because it's better than it costs. The exhaust came earlier than expected, but took a while because it was on backorder, and let me just say that it is a beautiful piece of craftsmanship. The blued tips are very vibrant and fit perfect with my Lapis Blue WRX. The sound is the best I have heard on a WRX in person, I have a MAP Catless Downpipe as well, but isn't stupid loud all the time. It has a deeper tone to it and is pretty tame while driving around normally, but when you step on it it gets LOUD. The look of the dual tips is different and I have gotten a few compliments on the look as well. I would highly recommend this exhaust to anyone that wants a loud exhaust that can be tame when you want it to.

First off. I am no mechanic. I've got no experience in putting on exhausts or anything. Yet this project only took me about 2 hours by myself. Simple enough to put on. Exhaust sounds great and throaty. Now very loud if that's what your going for. But a good solid deep tone. Cannot beat this for the price and quality.

Just installed the N1 Style Invidia exhaust on my 2016 WRX Base and it sounds phenomenal! Much more aggressive tone at idle and under acceleration but not too loud that it's obnoxious and overbearing. Minimal performance gains, but that's expected with the stock downpipe, but the power doesn't drop off as much past 6000 RPMs now which is certainly a benefit. Great fitment, I would highly recommend the GrimmSpeed OEM to 3" Exhaust (available from SubiSpeed) gasket to minimize leaks as other I've heard some people say that the fitment isn't perfect without the gasket. Overall definitely worth it, tuff looking and sounds amazing!

At first my wife and I were nervous about installing the exhaust, since it was our first time putting something on the car, but through out the process, we found it really easy! Installation is really easy and the turnout was astonishing! I love the sound and tone of it! It is louder the the stock sti sounds and more aggressive as well! Overall... I was amazed how everything turned out!

Okay so I was a bit skeptical of this at first because of the price, I don't like to go cheap, but I pulled the trigger and WOW. I think it was to my door 3 days after purchase. Installed this in about 1.5 hours with a friend....never done an exhaust before. By far the hardest part was removing the OEM exhaust. That took 75% of the time. Fitment was great, the exhaust sounds AMAZING. If you arent used to loud exhaust, this will be plenty loud. The sound is bass heavy, with a bit of a growl. Its pretty loud on a cold start, but once warm its actually very quiet on idle. When you are moving though this exhaust comes to life. I've seen mixed reviews on droning. I've got about 300 miles on mine and it only drones if I lug it on the highway in 5th or 6th gear. It's not loud at all while you are cruising, so it should be good for road trips. Sounds like a true performance car at WOT. The sound is almost intoxicating. Can't imagine getting anything better especially for the money. Also, The burnt tips look sooooooo good on mine(crystal pearl white). If you're on the fence you for it. You won't be disappointing.

First off its the best catback you will find if price is important since most others cost over 1000. The install was okay but confusing at first. It turns out the stock downpipe has an inner lip that helps connect it into the new midpipe so the size difference will not cause leaks (do not use the oem donut and you dont need the grimmspeed adapter) mine has no leaks. I ran into an issue of the y pipe rubbing against my spare tire but this was easily fixed just by slightly denting the spare tire location( minor dents and the spare tire location already has dents to show its a spare tire so its not noticeable that i had to dent it further) i am not sure if that will be necessary for everyone or i just didnt do the best job at aligning it. As for the sound it is fantastic i love it and isnt overly loud. It does drone a little on the highway but the wrx suffers from so much road and wind noise its barely noticeable.
