I'm getting everything set to install my 1 7/8 pacesetter LTs with 59959 cats. If you guys are interested I will take a trip to the dyno and get a before and after. And later on get one with a tune. This is on a stock 6.0 so it'll give the beginning guys an idea of where to start

 

I'm always interested in before / after results , please do

 

In for results

 

Numbers are always great!

 

I would not bother doing the dyno until you get tuned. You should retune after doing mods, just the way it is.
