Worth Redoing Exhaust?

it would probably gain you a couple ponies, but i would spend that money on a tune first. that will give you better results in the long run.

The LT's benefit over Shorty's is all about ... Torque

You will pick up a good bit in the low to mid range

As far as Peak Power ... it will be much less than the torque gain

Their benefit can be so easily seen in dyno pulls if you focus in on that area

Also LT's can make a difference which can really be felt

On a Street Car when you go down with the skinny pedal from a cruise
and
Don't move to a lower gear

I highly recommend them
