If I remember correctly doesn't Home depot or hardwear stores have rolls of rubber silicone hose's 1"-2" in rolls where you can just get the length you want and just cut connections out instead of buying the $$$$ ones for $30 a piece. I thought they did and I'll have to goto Home Depot today and check but has anyone else heard of this ?

 

yeah, i beleive they do, or lowes or wherever

 

But will it resist the heat in the engine bay? The turbo can get pretty hot.

 

yeah

 

check out www.turbopiping.com the prices for connectors are very good and not much more than you would pay for the homeboy depot connectors.

 

OK prices on the 90' elbows on that site.
For straight sections/couplers, and if you can do with out the bling bling colors, you can get 'wet exhaust' hose or 'turbo' hose from a marine or diesel supply store for about $1-$1.5 an inch (the 2.5id). I've found them in both black and blue.
