Best short tube headers?

I see a lot of stuff about long tube headers, specifically Doug Thorley's, not too much about short tubes though. What are some good shorties in terms of horsepower and torque gains?

 

from what ive heard doug thorley makes the best long tube and short tube headers.

 

Do they shorten the life of the cats?

 

i wouldnt think so

 

If u get long tube u will need o2 simulator. Just installed short Doug thourley ceramic headers. Awesome no need for simulator

 

how do they shorties sound?

 

They sound great! I have 2.5 inch duel exhaust and left the cats on for now. Took two of four cats off and kept gettin eng code so put back on. Im gsttin ready to install supercharger soon.also live in colorado and emmisions sux out here to deal with that's why didn't get longs. I paid around $365 for headers.
