I want to do it for sure, but new headers, cats, replumbed exhaust and new tune is going to be well over a grand and probably closer to two. I'll be putting that into the project car first. But I will get to this. Not quite sure how best to do it to isolate the effects of back pressure. Just inserting some hi-flow cats in place of the stock cats, measuring back pressure, and if essentially gone, dynoing might be the best way. Changing to LT headers, new injectors and tune, etc., there's just too many contributing factors to increased power.
