I think this coupler is cheaper than buying an SLP smooth bellow...

Just found this and hope it helps some folks who are looking for smooth bellows for LS1s. The 3"-3.5" is the one I would get. Plus it comes in 3!!! different colors!

How long do they need to be and could you use one with a stock airbox? If so would it make a difference in hp?

*98TransAm*

dont remember at the top of my head how long i got it, i just measured the factory one and went from there and NO there is not any horsepower gains from this, its more of an appearance mod. you can use it with your stock air box

Yeah I did the coupler "free" mod. Of course $5 is cheaper than $25 but I'm sure someone want's one that's prettier!

Probably so. Measure the diameter of the TB and see what you come up with.
