Ok, there surely has to be someone on the board who has tried magnaflows catback exhaust to back up these claims of the HP/TORQUE increase. Before I call magnaflow to ask them, have any of the tuners (Johnny, Jim, Sal...) on the board contacted them yet to question them about their dyno numbers?

 

HP/TQ increase

not gonna get additional HP/TQ

 

correct me if I am wrong but don't the L's have walker mufflers? Walker is a pretty repected muffler company. Not mainstream popular but popular w/ racers, etc. I know a lot of guys who run them on thier not so street legal cars

 

Many moons ago, when I first started reading these boards about the Lightning, I found that the stock exhaust was pretty much designed as best as it could. This was backed up by numerous users here saying that a new muffler/cat-back gave nothing as far as performance gains.... Only gave better looks and sound.

For me, that was enough to upgrade to the Magnaflow. I love mine.

 

cat backs provide only auditory enhancement to the overall experience, nothing more.
