I DO have silicone couplers in the few hot spots, but the rest are fernco, even the one in my intake mani! BTW, they've go some fucked up sizing thing listed on the labels that don't acually reflect what size they really are on the inside...so take a piece of you piping with you to double check your sizing.

Here's a link to what they look like....best part is, they are only a few bucks each

I think i spent about 100 bucks on my setup..piping and all...

I just picked up full intercooler piping for $49. That's the best deal anywhere.
