Cat Delete Gains?

Anyone care to venture a guess/perdiction as to what kinda ET and HP gains I'll see from cutting off my cat and replacing it w/ 2.5" pipe?

Not much at all, it's more of a sound differenece.

Granted you more than likely will pick up a hp or 2 but nothing you will be able to feel.

i dunno man, i think ur gonna be wrong, but we'll see...i'm gonna run the car this weekend, will post results ASAP. Should be interesting...

Cuda_dude's right. Today's cats have hardly any restriction at all - this has been the case since the 80s. The days of the beaded restrictor are long gone.

my very amateur guess would be a couple horsepower...i think mostly your notice the mpg differents...........let me kno what happens ...im about to do it to my Z

I lost mpg on my 3.8l, so did my cousin on his.

I gained MPG on mine, and if you do it properly you should also pick up. I'd bet you don't have a tune 6? If so, they didn't sufficiently delete COT protection.... this basically dumps in extra, unnecessary fuel at WOT purely for the sake of savign the cat, because lean conditions kill cats.

Nope, no tune. I still have the SES light on.

Some times you win and some times you will lose.
We now you are going to do . That is one way to find out.
Let us know how it goes.

rained out, will let u know when i get another run on it!

ok, had to say, there was def more power there, but the rear radials are shot, so i was still running 13.7's....trap speed was consistantly 101-102mph, where it's typically 98-99mph though....jury's still out.
