After a host of other mods, i finally had the capristo fitted with the Hyper Flow Cats. This actually wasn't straight forward. Neither the Capristo or Hyper Flow Cats fitted / worked perfectly out of the box. The Hyper Flow Cats should yield big HP gains. I bought these from Ricambiamerica. They definitely make the car louder. See link below. After a minute, you can hear the exhaust with the bypass on. It was a pain fitting the cats. They are smaller than the tailpipes they meet. Too small. Silicone and a clamp did the job for now. Could have been a tighter fit. I can't even remember what it sounded like stock. Driving under throttle, it is very nice. Post any feedback on the sound or on experiences re the cats adding HP that you can 'feel'. I can't say i feel the difference in performance. Its definitely not slower but i cant tell if its quicker yet. Will need to spend more time in it.
