    JBA is your only choice! They make a mid length header with a bolt on X pipe that can be modified to fit a MM.

    Tune is best bang for buck, changes the stock shifting from always up shifting and down shifting. Keeps car in power band better

    I dynoed about 272 with a JLT, SW LT's + factory exhaust, and a canned lidio tune. I guess my numbers weren't as bad as some Marauder friends had led me to believe if you got 277 with a full exhaust.

    My car ran a 13.9 NA on street tires with the mods listed above + 4.10 gears.

    The black car does not have 4.10's but it does have a full SW exhaust, I'd like to see if it can also crack a 13.9 in cool weather.

    To the OP: SW headers are absolutely worth it. Better fitment/flow over the kooks, easier access to the starter as well. Kooks also had a problem back in the day with cracking at the primaries (same with the OBX knock off of kooks). This happened to a friend of mine with kooks on his 04 Sport. Back in the day people bought the Kooks because it was the only option, when SW came along it's been all anyone buys.

    The way my black car is setup now is how these cars should have come stock (realistically speaking), it would have been respectable performance for a car it's size in 2003.

    Those dyno numbers seem extremely high to me.

    My stock 03 put down 217 stock and 229 with a tune but has 254k miles.
    My friend craigs 03 put down 228 with a tune he only has 35k miles on his.

    heres an old link where others were in the ballpark as well

    if any of you are ever in your marauder around the new orleans area come stop by my shop and get a free dyno pull to verify. I'm curious to see.

    He mentioned he's in new Orleans. It's pretty humid down there... It is at sea level though.


    Of course there are many many more factors... In my area (SF bay) we are cool and at sea level... But the idiots in Sacramento mandate we mix our gas with 10% corn juice. That'll affect things too.

    Dynos have parameters to adjust for humidity and elevation.
