ok guys i need to fab up a intake coupler i recently swapped a LS3 into my Trans Am and now the smooth bellow doesnt fit right, i need a silicone coupler that is 4"IDx6.5"L and a 30 degree bend. i have serched all over the internet and the only ones i seem to find are 45-90 degree and there always a inch to short.

HELP!!!!

Why don't you just use one like the stock bellows which would be an accordion style. Then you can bend it how you want.

^This. Or check your local home improvement store for the rubber plumbing connectors. Many do that because it's just as effective and cheaper.

I would prefer the smooth style. An I have looked at home depot there rubber couplers are only 4" long I need atleast 6" (that's what she said). Plus I have been told the HD rubber ones can collapse at WOT

Silicone Hose

I used this on my H/C/I LS1, and it worked great. To get the angle right, I cut the part that connects to the throttle body at an angle, so it pointed upwards towards the lid.
