Everything You Need To Know About Your 94-04 Mustang’s Exhaust

Everything Exhaust

Ok guys, heads up – I’ve broken this article down by exhaust component to cover as many of our common Mustang exhaust questions as possible. If there’s a question you have that isn’t answered here, then you know what to do! (If you’re scratching your head right now – the answer is call/email us!) You can also check out our tech article on Understanding Mustang Exhaust Systems if you need a refresher or some basic info.

How does an aftermarket exhaust improve my car’s performance?
I’m sure many of us are familiar with the “air pump” analogy – that is, an engine is essentially a big air pump, and the faster we move air into and out of the engine, the more power it will make. Therefore, replacing your factory exhaust with a larger, freer-flowing aftermarket exhaust can improve horsepower and torque.

What’s the difference between long-tube and shorty headers and how do they help my car?
Long-tube headers can also be called full-length headers, and require a shorty mid-pipe, oxygen sensor extensions, and a tune. Stock manifolds restrict airflow, especially on 2-valve engines. Tuning is required because long tube headers relocate the oxygen sensors further down-stream than factory, so a tune is necessary to compensate for the delay in response. For all you track-rats out there (or anybody who’s looking for a little extra kick from your pony) – long tubes are the way to go. Shorty headers are a direct replacement for your factory exhaust manifolds and do not require additional parts or tuning. Power gains differ between the two as well; long tubes will see the most gains in the mid-low to mid-high RPM range, while shorty headers will see their biggest gains in the mid-RPM range. Shorty headers are a great upgrade for your daily driver, but long tubes are best if you’re going for all-out performance, on the street or the strip. Another option for your Mustang headers is ceramic coating, which is more durable than chrome, and absorbs heat better.

The last few weeks behind the scenes here at AmericanMuscle have been 2011 Mustang chaos! Our Bama Custom Tuning team has been locked away, testing and refining calibrations for the new 5.0 platform.

As proud as we are to announce that Bama Custom tune files are now available for your 2011 5.0L Mustang through AmericanMuscle.com, we are even more excited to have become a trusted partner for many of the aftermarket test products that you will see. This means that our Bama calibration experts are first in line to develop precision custom tunes for many new products before they even hit the street! All tunes are not created equal, and we plan to show you how ours are superior!

My Mustang Fotofix: Mustangs at the Ballpark Edition

We figured we’d get some pretty cool pictures when we announced our Mustangs at the Ballpark Photo Contest, but we had no idea how many awesome photos we’d receive. Narrowing the field down to three winners was a tough job, and there were a lot of great pictures we still wanted to share with everyone, so we decided that a FotoFix was in order. We’re showcasing eight of the coolest pictures that were submitted. Whether in a major, minor, or little league stadium, Mustangs always look great at the ballpark.

AM’s Stock 2011 GT Runs 13.0’s! Check Out the Video

We recently took possession of our 2011 Mustang GT 5.0L Automatic. There may or may not have been excited giggling as we poured out of our offices to catch a glimpse, but we’re not at liberty to say! Our first impression: this car begs to be pushed to its limits. Small styling changes in the interior are completely overshadowed by the massively impressive upgrade under the hood.

Most of us remember the original 5.0L 302. When Ford released it, it was under-designed and under-powered, and there weren’t any real aftermarket performance parts available at first release. Thankfully, that won’t be the case this time around. The biggest names in aftermarket Mustang parts are developing sweet performance upgrades, and we’re working right alongside them. Our vendors are working with us exclusively to test parts, as well as research fitment and performance. We’re going to be building our GT the same way any enthusiast does—right here, in our garage. Along the way, we’ll be showing you more coverage of our mod strategy and giving you examples of real world numbers, both on the dyno and on the asphalt.

Needless to say, we can’t let a car sit for long. Within hours of delivery of our 2011, we were all thinking of one thing – Maple Grove Raceway. We broke it in as quickly as possible (the hardest 2 days ever!), and high-tailed it to the track this past Friday afternoon for some baseline testing. We were pleased with the times, considering we ran it at the track in its bone-stock condition. Our team laid down some impressive numbers out of the GT, with consistent times of 13.034 at 109mph and 13.022 at 110mph. Check out the awesome video below to see the team flying down the track!
