Ok I used to own a Si it had a intake and a catback exhaust (flowmaster deltaflow) with a 3" tip NO RICE it was lowered about 2"s Talk about a dog, well compared to the SVT. I am not dissin on the car but it wasnt all that. Those cars can be monsters with the right mods but a fairly stock Si couldnt hang with my SVT. But then again there are alot of things my SVT cant hang with....
