Im putting a Greddy SOHC turbo kit on a d16y7 and I have the d16y8 intake manifold. My ? is since the D16y8 has a sepreate exhaust manifold and cat, will I have to buy another cat to keep from being open header or will the Greddy manifold reach the stock exhaust??? Thanks (and please dont flame, I havent gotten any of it yet, and I dont want to spend another 300 dollars on a new exhaust right now)

 

i only way it will work is if you buy a d16y8 exhaust system. The GReddy DP will not fit the d16y7.
