holset exhaust housing question
 

hey guys right now im running a holset h1c with a 18.5cm housing on my sr20 with one port blocked off . as you can imagine.... it lags. who would of guessed? it looks like the smallest one i can find is the 12cm housing. is there anything smaller? i would like to stay twinscroll, im not utilizing it at the moment but i plan to later down the road.

not a twinscroll, it says hx35 but im pretty sure it will bolt onto my h1c. right?
