    Straight pipe??

    True power isn't found in the exhaust, it's in the tuning.

    04 axle

    Try asking for the diff cover for a truck with the "TOWBOSS" package. The "TOWBOSS" was only on the DRW trucks and the package has the same style aluminum cover with the cooling fins but in the Dana 80 size.

    '07 clarification

    The 6.4 is a totally different engine. ALL 6.0s will be basically the same when you are discussing the emissions junk. It makes no matter the year the truck was built, the difference is the model year. MY08 is a big change for all the diesel motors. All the current 6.4L are built in 2007 BUT...

    Difference of F250 vs F350SRW

    Thed only real difference is the rear block height. Just about everything else between 250s and 350s SRW trucks is the same. The front (Dana 50 or 60) and rear axles (Sterling 10.5") are the same throughout SRW trucks so there is no difference in ring gear size for the 99-current trucks. DRW...

    18" Stock Wheels 2005-2008 F-250/350

    The backspacing is different for the newer coil suspension '05- current trucks. You would need a wheel spacer to run them on the leaf spring front 99-04 trucks.

    6.0 Straight Pipe Video

    I haven't been impressed with the Amsoil and since the price is better on the Rotella and Valvoline I'm switching back. Don't expect to get better than 7k out of the Amsoil......

    6.0 Straight Pipe Video

    I can't remember if it has always done that but I think that's the way she runs. I'm switching to the Valvoline or maybe going back to Rotella on the next oil change.

    MBRP exhaust w/o muffler & converter

    Performance gains are NOT due to exhaust size but the EGT's will be much lower. If you were to add ONLY an exhaust system 4"-5" you will not gain you any HP&TQ. In fact the truck may loose low end power so it will feel like less HP is there. Now looking at the "system" approach to doing...

    Ford SD in a Tundra video

    Okay so I was looking at the "hype" over the Tundra. Well if you watch the "Behind the Scenes" video you will see a Super Duty in the background during one shot. I'm thinking it's a 7.3 but it's a Ford Super Duty for sure!! http://www.toyota.com/vehicles/minisite/commercial/tundra_tv1.html...

    SPRING QUESTION

    BTW the 2wd (READ: Two wheel drive) trucks have front coils. Don't confuse the 2wd trucks with the 05-current 4wd trucks.

    MBRP exhaust w/o muffler & converter

    It's not really that much of a sound level increase. Everything is bolt in so if you don't like it put the OEM stuff back in.

    exhaust 4 or 5 inch straight pipe

    If you are a prue power junkie with tons of mods or a puller running mods then there is a fair difference. A shadetree power adder with the standard mods would not see a significant difference between the two sizes.
