your not going to gain shit for HP unless you do a full exhaust
what the point of adding a intake to make the motor breath more, but keeping the stock exhaust to choke it out??
it all works together…intake/ exhaust then a tune. With a full intake and exhaust you can then add more timing in the tune then just with a intake. The key to adding more power is all there in timing. Get more air in, get the exhaust out asap
also, your talking about a lower compression motor then mine so power gains from minor bolt on’s arent that great. Yah they help, but you not going to see 50whp from full bolt on’s.
