bba motorsports has turbonetics ones as well as generic reinforced stuff, don't get straight rubber $hit, it will swell and may bust like a balloon (leaking precious boost!)
The stuff at hampton Rubber is the reinforced silicon type, not cheap shit. I beleive its the same one sold by baker and has held quite well on my car at 18 psi...
I have about 18" of 2 1/4" reinforced silicone hose for sale, blue outside orange inside, its the same shit most turbo kits use, just cut it to length
btw its good to 75 psi
temp range -65f to +350f degrees
