??? -- no cat , whats setup going on there? running bigger diameter of pipes will slow exhaust flow not getting enough back pressure. or replaced with cheaper test pipe/cat gutted doesn't have baffles/air for back pressure . running idle up to half its getting by not needing as much air to fuel ratio but its calling for more air at full throttle and not enough time for it to make air. a smaller engine wouldn't be noticeable /wear and tear on other parts modify/changing exhaust system . but...

pcar is a big v8 engine and to add no dummy , just try to get one over on it,lol. it knows.
