Catback...Am I missing out?

axleback is just a noise preference

oh i was asking about it throwing codes if you replaced just the secondary cats with straight pipe, not using an aftermarket exhaust.....i guess if you did it "custom" is what i was saying. since it was discussed that the aftermarket exhaust wasnt worth the 1200 ish price

Don't discount the 20-40 lbs weight savings along with the power gains.

Gains are typically in the 10hp range - its about the last mod I would do, unless you really want the sound. However the ~40lb loss is nothing to sneeze at.

Weight savings is about 40-50 pounds. That alone will help the car go faster!!
