I have an 02 screw 4x4. I was on Magnaflows website last night and they DO have a cat-back kit for my truck but it is SI-SO. NO listing for a SI-DO which is what I really want. I know that my screw has the same wheelbase{139} as an extended cab w/ the 6 1/2ft bed. Can I use the p.n for the x-cab short bed w/ the SI-DO?

 

i have a SI/DO magnaflow exhaust kit. Go up to your local speed shop and he should find you one.
