So I did a search and there doesn't seem to be any opinion on silicone couplers. If I'm going to spend the money I might as well make sure I'm not going to get a knock off product. I seem to be coming across Mishimoto, Vibrant and it seems Hose Techniques isn't making any new stock for a while.

Does anyone have any input on brands??

 

I purchased all of mine from Speed Shop on amazon. Best price/rating I could find.

 

But what brand??

 

I've used HPS, pretty good selection but a little pricey.
I bought one of the large tubes and cut it into smaller sizes.

 

I just bought all HPS from amazon.

 

I have HPS couplers. I have never had any issues with them on any of my boosted cars. You get what you pay for!

 

I've personally used Vibrant on all my cars. They've been great!

I got mine from verocious motorsports off ebay. Cheaper than HPS & seem to be good quality
