restricted throttle body

I was wondering if there is a smooth rubber coupling for a stock ls1 throttle body between maf and throttle body? The stock rubber is like an accordion and seems to be restrictive. I thought, at one time, I saw a smooth straight coupling. any helps thanks.

SLP makes a good one, it's not cheap. They call it " Smooth Bellow" #23065

Fernco is probably the best bang for the buck bet.

Although, it looks like you spent $5.
I want to change mine (I use the same stock one as you're describing) but I really prefer the OEM look. Haven't really found anything that looks better yet.
