Hi all, I'm thinking of putting a downpipe, intake and Ralliart computer into my Evo VI. The car already came with a full catback. Will I need to install head studs with just these few mods?

Thanks in advance!

 

Hell no! Buschur Racing is putting out 380 hp at the wheels on the completely stock EVO VIII bottom end and I don't see yours as being that different. You will be fine until you are making a lot more power than just a computer upgrade and exhaust upgrade will gain you.
