I looked under my truck and didn't notice and exhaust sensors. Will it help or hurt in the long run?

The removal of the muffler and replacement with a performance muffler or straight pipe if you can stand the noise will help a lot they say. Mine still has the stock exhaust and with the Predator on 100 HP and A K&N FIPK my dyno sheet on my gallery shows it makes plenty of power.
Some say they pick up as much a 2 MPG improvement in mileage witha 4" system. It would take lots of tanks of fuel to pay for it.
I think it comes down to being able to say mine is bigger than yours. By the way, I plan to put one om mine as soon as it cools off here in Texas, but you know what I mean!

you may have to post a dyno with those kind of numbers !!!
NO ONE has produced those kind ---
not even the fictional marketing execs at superchips !!!
And the customers have been more or less disappointed with the numbers !
