I hear you Jac. A good compromise would be a 1.75 bundle to the collectors if Kim is going to thrash it on the track. For the street and shows the stock 1.5 set is probably fine. I don't have any clearance issues like AJ has using the RCR stainless 1.5 set,306, and g50 trans. I'ts possible the engines are installed too high, or not tilted front to back? Dunno. I will post a pick tomorrow. If I remember right my engine is level....... S
