utwrestler, fahr side says he hasn't seen any gains from just a catback. i regard his input a lot
higher than most people's here and what he says is also in line with a lot of what other people here say that have the experience to back it.
JMHO, but a CBE exhaust is a waste of time and money because you'll likely replace it within a year and it's value will be nearly zero. Save up for a TBE and a tune. HUGE difference.
a TBE is inclusive of a CBE. the problem with what you said is that you told people to save up for a TBE in your second sentence, but in your first sentence you said that a CBE is a waste. i think maybe you meant to just save up for a downpipe, right?
also, your use of the word "value" is a bit ambigious. do you mean performance value or $$ value? i'm assuming you meant performance, in which case you'd be right. little or no value. if you meant $$, you'd be wrong because people do resell their CBEs for a decent return on their original cost.
