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.

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.
