Looking at a leveling kit,cat back,and cold air intake.
What experiences have you guys had and what do you recommend?
Stock 03 Expy........blah

 

Whole Lotta crickets............

 

Trolls should stay under their bridge and never come out.

 

So no one has modded their Expy? Just drive it? I find that hard to believe.

 

Hey just saw your post. Seems very few on here are into modifying for better performance. Usually get a response about how big and heavy it is and that its not a race car. That being said I enjoy playing with my 06 Navigator. Ive added a magnaflow 3" cat back exhaust and an SCT tuner the tuner made a big difference on how the truck feels and drives. They tune the throttle by wire for a much quicker feel. Even though SCT cant tune my 6 speed transmission it does shift out of high gear alot less so that would seem to indicate that the horse power increase is for real. Over all I like it and I like the way it drives and feels.

 

Thanks diverdom. Did it improve fuel mileage at all?

 

Actually it seems like it did. Ive only used the dash mileage as a gauge but when I'm not hammering on it like just going to work and back it is up about 2 mpg. might not seem like much but it makes me smile to see 16mpg and 17 if i"m not going over the hills here in upstate ny.

 

That's big. We travel 300+ miles to Kansas three times or more a year,so that's what I need.

 

Im running a 93 octane performance tune. You get three tunes with it and you get to choose what works best for you

 

Excellent. Thank you. Reps sent.

 

As you can see by my signature that I have modded my older Expy a good bit. Made it alot more fun to drive. My wifes 03 Explorer with the 4.6 has shorty stainless headers, Magnaflow catback, K&N cold air intake and stage one cams. Picked up about 70 hp.
