Doug Thorley Headers?

Do they make em for an 02 4wd ECSB?

Are they effective?

I have them on my truck, they definitly make your exhaust louder and you get a good HP gain. my truck is a 2000 gmc RCSB and i bet they make them for yours. Get the Tri-y's, not the shorty ones. Summit racing sells them
