Default My Experience with 11-14 WRX/STI MRT Turboback

Recently, I had the opportunity to work with Scott Hoag and his team from MRT Performance based out of Plymouth, MI. It started with taking photos of their 2015 TKO Mustang which was a 2014 SEMA vehicle supporting the new ecoboost engine and full customization offered through his facility. After a few conversations it had become apparent that branching outside of American Muscle was of interest and seeing how a tuned exhaust would perform on a JDM vehicle. I was more than confident with Scott and his team knowing of his background and his love for all cars in general. (I've attached a video of Scott below)

We started with my 2012 WRX hatchback which had the SPT exhaust from the factory and ended up with a full turboback designed and tuned for this application. This 3-inch exhaust allows for an unrestricted exhaust flow enabling the car to breath freely, all in which creating an aggressive sound. In order to tame this tone at cruising speeds it includes the very first drone management system available for the WRX, which insures a more comfortable ride for enthusiast. CNC Mandrel bending technology ensures that our turbo-back exhaust systems have smooth bends and precise fit. Built from the highest grade 304 Stainless Steel I know that this system will last for many years to come!

With all of that said, I've been driving the exhaust for about 1 week now (mainly highway) and fall in love with the unique tone it offers ever time I get into the car. The volume is present, but not overbearing due to the drone management. It is almost as if I am more in tune with the driving experience now that the MRT exhaust was installed. Volume-wise, it is slightly louder than the SPT w/a catless downpipe, but you don't receive the head banging headache from highway driving. One of my favorite feature is the quad 4" tips which fill out the rear valance as if they should have come from the factory this way. Check out the pictures and videos below!

Looks great and I love the 4 inch tips. Are there any plans to make a sedan version?

Funny that you mention this. I also own a 2011 Sedan which is being used for the development. I'll continue to update this thread with more info on the sedan.

love the placement of the mufflers on the hatch. This would allow room for an airtank outside the car.

There is more room. Possibly for a smaller tank.

I was close to picking up a Greddy Evo3 exhuast since it had the 4 inch tips, but they're discontinued and superseded by a 3.5 in system. Around what would the price be for the exhaust?

It's sold as a full turboback. Pricing can be found here: http://www.shopmrt.com/product-p/98p111.htm

This is tuned drone management which also aids with proper amount of back pressure.

Update:

I've now put on more than 1000 miles with the new setup and the car is feeling just as good as ever. The exhaust is pretty well broken in and the overall tones are holding true without drone on the highway. Overall, I'd compare this to the volume of the Q300 exhaust by Invidia, but without the dreaded drone at highway speeds 65-80 mph. While I can clearly hear the exhaust more than my old SPT w/catless Invidia downpipe I can easily make sales call on the road for work without being worried of volume coming through the cabin notorious to hatchbacks. I'll continue to provide updates on the exhaust as I daily drive the car until the sedan version is complete (the sedan will be my daily driver throughout winter).

My sedan was used for the development of that version as well. I should be getting it back soon. I know that they've been working hard to offer both a catback and turboback for both versions now!

Just received another shot of the sedan catback. I'll be able to check the car out on Thursday.

Setup looks good. I am on their waiting list for the catback as long as it is sold at a reasonable price.

I'm going to be back at their shop on Thursday to check it out. I know we are talking to Open Road Tuning who is a dealer and wanting to run a group buy. I'll be sure to let you know more.

I was just at MRT yesterday and I heard that they'll be announcing the group buy through Open Road Tuning later next week.

MRT was working on the video taken of the catback when I was there. I'd expect to see it shortly as well. I'm sure ORT will be having a thread of some sort or it'll be on their site for the group buy.

I've been running the catback version on the sedan for a few days now and I can say it really does sound amazing. While it is a more refined sound considering the rest of the car is basically stock (CAI and air ride).

There is no drone when mated up to the stock downpipe and a lot of the turboback characteristics are still present. Obviously, my hatchback is fairly modded and the turboback is much more present, the catback is a blast to daily drive!
