This product is of very good quality nice silicone hose and everything is nice and clean after installation. HP was gained a tad jus a little I accompinied this with the DP install so the turbo can be heard very well now especially when u get on it the thing whistles and whines like never before. IMO the intake is a great addition for better airflow and makes the turbo "TALK" I guess u could say but the HP gains are hardly notice able maybe like 5 or somethin of that nature but hey every little bit helps.
