    Which 4" to 3" reducer?

    I have seen folks buy the one from siliconintakes.com, but lafjax said it is too small and said to get the one from Stealthworks.

    Has anyone had problems with the reducier from siliconintakes. I found one thread where a guy just cut a small "V" into the siliconintakes to make it fit.

    Thoughts?

    I've bought 90 degree elbows from both places. I wish I could remember which one I liked better (I haven't used elbows of the SC in a while). But, any 3" will work, it will just be slightly larger than the SC lip, because the SC inlet is something like 2 7/8". Cutting a little "V" out, or just clamping down tight with a good strap, will work.

    The 2.5" silicone coupler will fit over the SC outlet without cutting it, it just a tight fit.
