on my car i have 1 3'' tbolt for the tb is all most bottomed out , 2.5'' for all the ic pipes and 2'' for the pipe from the turbo to the ic
Well napa has all but the 2'' and i paid about $3 each , i had to get the 2'' from turbonetics and it cost like $7 so yes napa is da sh*t

 

For the smaller sizes I recommend going with the Breeze constant torque series, Napa stocks those, again at least the ones I patron, http://www.breezeclamps.com/ct.htm Also no matter how tight I got a t-bolt clamp on my throttle body it would always pop off. I figured it was due to the Breeze band being wider than the stock hose clamp band and not catching that little retaining lip on the end of the tb inlet. This was when I was on stock i/c piping.
