1998 GMC 6.5T 2500 ext cab short box (no EGR)

I see lots of information on the older 6.5's but I don't see a lot for the 98 and up. I just finished changing the glow plugs, lots of fun at #8. Is there a need to change the air box. K&N only show a filter for this year. The exhaust on my truck is stainless, who in Canada has the aftermarket exhaust pipes for this beast. DSG prices are really high and they are not stainless.
