a honecomb to straighten the flow or a plenum to give it some intake length to straighten the flow should make it better.
I've got the stock exhaust with cat intact. The exhaust note seems to come up with just the cone filter. Past half throttle you get a nice honk/growl out of the engine. Below that it's still pretty tame.
Prof Stack,I think you're right, should be fine with your filter setup. Were you tracking mpg befoe you installed it? Just wondering if you can do a comparison.Scott
Have you checked since installing the new filter? Any diff?I would attribute my drop to 'spirited' takeoffs since the install but I think 10% is too much to be accounted for from just that.Scott
