Cumon' guys... don't dissapoint me now!
You note that backpresure is highest close to the headers. What sort of power difference might be expected by putting 200 cpi high flow cats in the location of the stock primary cats with straight pipe in the location of the stock secondary cat, versus straight pipe in the location of the stock primary cats and 200 cpi high flow cats in the location of the stock secondary cats?
