Hi all,

I am new to the site. I've had 2 Mustangs but just picked up a 16 EcoBoost last week and I have some questions. I have had a local body shop delete the resonator and weld in a y-pipe. I am now looking to finish off the cat back with some axle backs or mufflers. The body shop says they can weld in Flowmaster Series 40 mufflers, or Magnaflow Street Series mufflers they carry in stock. Although, these are not specifically made for the EcoBoost. I am wondering, does this matter? If these are "universal", great. I just don't want problems with back pressure or hp decrease if the muffler isn't exactly for this car.

Thanks!

Torque

Hi,
A performance muffler will lose 10 ft/lbs of torque at low rpm and gain 5 Hp over5 grand if you are lucky. A tune is the best bang for the buck.

there will be hardly any hp/tq gains with a catback...if yu want to change the sound
then go with the magnaflows..very deep sound....if yu want horsepower/torque
increase go with a tune..better bang for buck..
magnaflow makes a street series for the ecoboost setup.

Actually, the biggest thing is the exhaust pipes. The stock pipes are 2 1/2". Most of the catback systems are also 2 1/2". Just welding on any muffler will only be a minor improvement, most noticeably when you step on the gas. For what you're doing Competition/Race/Atak are ALWAYS going to give more sound than "Sport" or "Touring" mufflers. Also, you want a "straight-through" muffler. Chambered are garbage and a waste of money, IMO.

Also, I'm adding an MBRP catback Race exhaust system and it most DEFINITELY will add HP AND RWT! About 17 for each w/out a custom tune. A custom tune would bring the WHP to about 33 and SIGNIFICANTLY increase the torque. So the post that said catbacks won't add/take away HP/torque is mistaken.

Hope this helps whoever reads it!

I highly suggest you find someone with a similar setup first and listen to their car. Although exhaust sound is very subjective, I'm finding that many of the available cat-backs & muffler options available for the '15 & '16 Ecoboosts sound like complete CRAP! I totally realize you'll never get a traditional "Mustang V8" sound out of this I-4, but I also know that I don't want it to sound like riced out Civic either.


I've been spending a lot of time on YouTube listening to different setup's. So far MAPerformance is the best sounding IMHO.

Hey if you want a cheaper exhaust get a magnaflow Muffler 12288. to replace the resanater , run 2'5" out to the tips, should be able to get done for 500 at local muffler shop. sound like MAP system. https://youtu.be/ERoFkA5WBmo is the link.
Unfortunately that video is not quite enough to make an assessment of your setup.

Sorry.

U.M.

P.S. Money is not the issue. I'd even spring for a titanium Akrapovic exhaust if it sounded right.

https://youtu.be/ERoFkA5WBmo is his 2nd video. It does sound good, IMO. I am budget minded but want quality at the same time. Depends on what you want, I use to like loud exhaust in my youth , but i want quiet power. maybe a little ruble when i mash it but no drone when cruz'in ,, its **** getting old.

Agree 100%. Not looking for loud either. However even his 2nd video you referenced above doesn't allow me to make a judgement besides "yes it sounds good when idling". I need to hear revs, cruising, interior noise level, etc. before I make a decision.

I'm happy with the MBRP street catback exhaust. It's a lot lighter than stock, a little louder, and sounds much better.

MAP exhaust sounds great. I have one and it definitely doesn't sound like a fart can exhaust found on many of the import cars. None of the videos do exhaust sound justice.... best to find one in person to hear how it sounds. Not exactly convenient. I spent my hard earned $$$$ on the MAP exhaust system from the turbo back and I'm not disappointed.

Custom catback, 1/2 price of aftermarket

I went to Ed Hanson’s yesterday, and had them install this exact set up for my 2018 Mustang ecoboost. Immediately was impressed by the customer service (shout outs to Rebecca, Kevin and Steve). They took the time to explain to me what would best suit what I wanted out of an exhaust mod (freer flowing exhaust, deeper exhaust tone, sleeper looks). In the end, the set up you referred to in your link checked all the boxes. It’s a little more than $600+tax as of 4/19/19, but so worth it! My first experience with the new exhaust was when Kevin started up my car. I was still in the waiting room when I heard a much deeper rumble; I stepped out, and yes it was my car. Not going to wake up the neighbors, but definitely sounds better than stock.

I have the Ford Performance tune/CAI kit installed on my 2017. If I install the MAP catback exhaust, will this mess up my ECU software in a negative way or will it be a positive improvement for hp and torque?

Adding a cat-back should not require a re-tune of the ECU. It's the turbo-back/down pipe upgrades that require ECU re-calibrations. As for gains, there will be some measurable gains from a free flowing cat-back, but they will be minimal at best. To see the full potential of the new exhaust you would want to re-calibrate the ECU, however the cost of the re-calibration would outweigh the additional HP/TQ gains unless you're doing it yourself! Slap that catback on and enjoy the sound and the small added boost in performance. :D

Hello,

Over at thermal R&D we have an amazing system designed for the Ecoboost platform. Our system is made with T304 Stainless steel and designed and manufactured in California.

Our main goal with our exhaust setup is to provide unrestricted power to your system and minimal drone. We use a passive exhaust setup instead of the traditionally packed mufflers.

We hope to have your business and please feel free to reach out to me with any questions.

Thank you,

Victor.
