    Anyone run under mount FMIC piping? I was looking at the JBR set and someone tipped me off to the HTP version.

    JBR are silicone and people say they can expand. Yet, I haven't heard first hand issues.

    What have your experiences shown?

    Check youtube for some videos of the JBR tubing. I run the HTP under route, no problems.

    HTP under route piping if you're running high boost for sure. Lower boost you can get away with JBR. But overall I'd still vote htp

    I ran the HTP piping for a while. The piping kit is very high quality as far as materials and fab.

    I knew 1 or 2 people a few years ago that ran the JBR, no complaints either. Yeah the silicone can expand slightly, but it doesn't burst or leak.

    Htp is what I run. I have pressure tested to 50+ no issues. I dont think jbr can do the same with out issues

    50 psi you say?

    What t-bolt clamps are you running that can hold that much pressure?

    I ran the OG htp and it was great. Might have been placebo, but I do think I noticed a response improvement cutting out over 2' of pipe vs my old set up

    I ran HTP here without issues. Now they offer a cold side too. Ya'll lucky ducks. Speed Solutions also has an interesting under-route solution if I remember correctly.

    I love the HTP full under route kit, it's very high quality and fits perfectly with my GTX turbo.

    I just installed the full HTP under route kit. The fitment is excellent. I also have read forum posts about the JBR silicon piping expanding under heavy boost applications.
