Removing cats - pros and cons From all the threads that I have read here and ls1.com, I have gathered
pros -
more aggressive sound (subjective)
slight hp increase on top end
cons -
not street legal
loud/raspy exhaust
need o2 simulator
less backpressure - less low end torque
Has anyone seen / performed a comparison of a no cat vs. catted exhaust in terms of a dyno plot?
I am particulary curious in the loss of low end torque phenomenon that supposedly occurs with no cats (less backpressure).
Also, if anyone has something else to add to these lists, please advise.
i am currently in the middle of a header& exhaust replacement, and am debating whether or not to go back with cats.
