i talked to Tom @tbyrne he said they come already coated.

 

Considering they are fairly equal in quality / performance, I hear the TOGs are easier to install. If you're doing yourself, that may help decide.

 

that does help... i will be installing myself most likely.

 

tog and asm are great, i have MIKE HAMM'S on mine but don't know if he is still doing them. they require cutting and weld adaptors to the front of the cat's though. i'm in the snow and salt zone in canada too and mine aren't rusting.
do asm and tog require cut/weld as well?

Yes ..

 

My second set of ASM didn't lasted 2k miles before starting to rust
with no winter driving and i think one maybe 2 days of rain at most

 

does Arizona Speed & Marine have a warranty on their headers for rusting?

 

TOG's are warrantied for the life of the truck with the original owner I think.

 

well then... ive been getting feedback from other boards too, and it looks like i'm going with TOG's.... no the problem is i cant look at my truck since i'm not near it, and i dont know if i have A.I.R. or not... i cant remember.. i do know that the truck was originally leased in AZ for 3 years by one owner before i bought it.... anyone know about AZ and 2000 models??? ryan23silverado lookin for your input since your the only person i know thats from AZ here other than me.

 

i hear the LaPole headers are sweet too. and cheaper.
