Do a bunch of searching and light reading right here and on the superduty forum, lot and lots of discussions about V10 exhaust modifications.

Many go-fast parts and other goodies are available on this site.

Summit catalog is required reading as is the Jeggs version, don't skip the JC Whintey, though some of their stuff is crap.

Be prepared for some sticker shock as headers and Y pipe are usually $500 and up, ( not the $89.99 small block Chevy prices.) Same with most other mods.

There are many folks here who have looked at the pricey things and found a "poormans" way... worth reading about.

Stop in the quick mart and get one or two Truck and/or 4X4 magazines... tons of ads for EVERYTHING truck and actually quite a bit for the V10

I you poke F-250, or SuperDuty, or Triton V10 into a "Google" search you can spend hours learnig about all the different ways folks spend $$$$$$$ on their truck, and all the different companies willing to take their money.

Check out eurkaboy.com Stan has done an extraordinary job of cataloging his mods with photos and notes.
