my stinger is filed down quiet a bit and it still performs the same. I dont get wheelies off the start but the front wheels leave the ground a tad bit. i have the mid-top end pipe and it shows for it in those rpms big time.. you'll know when the power surge hits.. its like
.. but the truck takes off hard from the stop and will reach top speed pretty fast now with out uncontrollable wheelies. that why i like this mid top tuned pipe.... but when i want wheelies i know they are there
just as long as you punch it at midish rpms range it will snap wheelies all day long for me..
