94-04 V6 Mustang Exhaust
SLP Loudmouth Dual Exhaust
The first thing almost any V6 Mustang owner wants to do to their new Mustang is change the exhaust. Ford gave the V6 Mustangs a Y-pipe with a single muffler and tail pipe. This left them very quiet and with much to be desired. Therefore most owners turn to aftermarket exhaust systems to liven up their cars.
The exhaust system is made up of a few key components:
-Exhaust manifolds (aka headers)
-Tail pipes/exhaust tips
Some Mustang owners change their stock exhaust manifolds for long tube headers, and shorty headers have proven to show little to no benefit over stock exhaust manifolds. Long tube headers are louder and flow better than shorty or stock exhaust manifolds but some people run into issues with how low they hang.
The midpipe is the most common part of the exhaust changed, next to the muffler. V6 Mustangs comes with a Y-pipe from the factory. But on an even firing engine like these, you can really utilize straight pipes which may not be the best choice on a V8 Mustang. Other common midpipes are X-pipes and H-pipes. The X-pipe is generally more raspy and many enthusiasts will try to talk you out of getting one. The last note about midpipes is off-road (O/R) or catted. Off-road midpipes have no catalytic converters and therefore it is illegal to use them while driving on public roadways. This, however, does not stop most people from installing one anyways.
Mufflers are the most commonly changed part of the exhaust. Flowmasters, MAC, Thrush Welds, and SLP are all very common mufflers.
Finally there are the exhaust tips. Most people go with 2.5" to 3.5" tips with a Mustang GT rear bumper so they can run the tail pipes straight out.
