Super easy to install, and gives the motor a good look. Way better than stock. Would recommend to anyone with a few extra bucks!

Extremely good product. Unfortunately the larger tube didn't work for my engine but I used a Dremmel and cut it down to the right size. Much better support and a superb product! :)

Although my stock boost tubes were fine, I wanted to upgrade them to these fine silicone tubes for two reasons: a) I could see how the stock tubes could collapse or expand under heavy boost, and these thick and nice looking silicone tubes were my number one choice, b) the recirculation boost tube was rubing against the CS SRI, and I wanted to strengthen it by replacing it as well with the CS boost tube.

Installation was a breeze, the tubes are better than any other brand I've seen, the clamps are way more secure and air-tight than the stock ones, and I can feel the more steady boost levels. The recirculation boost tube, although slightly different in shape than the stock one, has a curve that prevents any rubbing with the CS SRI.

Definitely two-thumbs up!

Quality was great, very thick/strong construction. Looks good under the hood. Fit perfect.

Very easy install! These hoses are 10 times better than OE hoses! Plus the t-bolt clamps make for a great upgrade!

Good looking hoses with great install instructions (as always).

Perfect fit.

I have a speed 6 neck and but I also have a spare speed 3 down neck. Is there a significant issue if I switch the necks out to make the coupling work? Horsepower or performance issues?

i have a pu with a SU tmic (yea yea i know, got a good deal, i would have preferred to have a cs tmic to keep the engine bay looking stock). the SU tmic doesnt line up correctly with the stock boost tube that goes to the turbo, thus causing a cut from the clamp to happen in the stock boost tube and due to the improper fitment is causing my synapse sb bpv to have those vacuum/boost lines rub on the hood.... my question... are these exactly the same size as stock or are they a tad bit longer than stock? or is there a way i could order the boost tube to the turbo slightly longer to compensate for the poor fitment of the SU tmic?

so i had a boot gauge installed and they had to cut into my boost tube to install the t-clamp. anyway i think i might have a boost leak. Will this replace the stock boost house ans fix my problem?
