I have attached several variations of the modification, but they're all the same basic idea. Optimally, I would imagine that any gains would be increased by additionally installing a less restrictive set of slip ons. I'm outfitted with both TIG and oxy-acetylene in my shop, just to get that said.
When I ask "is it worth doing", what I mean is;
** any better raw performance (perceived improved torque, as in seat of the pants ... maybe more HP)?
** more efficient (fuel mileage)?
** sound change (deeper or louder or crappier)?
