=Exhaust=

"V8/Mustang sound!"
No cat-back or custom exhaust will give you that sound - it's a V6. There are options to make a nice sounding exhausts.

Differing exhaust configurations will create different sound outputs. There are a few choices out there, so we've compiled a database of exhaust sounds.

EXHAUST SOUND CLIPS

The SVT exhaust is a single 2.25" to two 2" pipes.

The SVT resonator is the most restrictive part of the exhaust. A popular modification is to replace the stock SVT resonator with a straight through glasspack or resonator. A popular one is the Magnaflow 10435.

=Injectors=
19lb injectors will support 225-240 FWHP (standard on SVTs), which is sufficient for most 2.5s.

=SVT UIMs=
Terry Haines confirmed that the UIMs from all model year SVTs are indeed the same. Ford changed the part #s because...who knows.

The 5 extra horsepower is a result of:
- later heads being ported, early not
- later heads have a revised/added intake port hone
- .25 compression ratio increase in later years

Rick Miller from Extrude Hone also confirmed that the UIMs from all model year SVTs are the same.

=Non-SVT Duratec Performance=
- One of the most popular exhaust modifications for non-SVTs is to bolt on the SVT exhaust. The only modification needed would be to add a hanger.
- SVT Lower Intake Manifold (LIM)
- SVT Upper Intake Manifold (UIM)
- SVT Throttle Body (TB)

=Differences 2.5L SVT vs. 2.5L non-SVT=
