Is it true that taking cat of give better perform and mpg and if you run straight pipe what do you do about the o2 sensor so lights won't come on and then does it need tuned up after that

 

Leave it on.


If you want to race, go buy a race car and take it to the track.


Just my

 

Not to mention illegal.

 

cats became mandatory in 1976... MANDATORY

do you understand how fuel injection works in a production car/truck

limp home mode!!!!!. do not mean it runs well.

 

Also to mention. The work and parts you have to buy out weigh the gains you'll get from it!

 

The cats on your truck are high flow cats. What that means is, if you take them off. You aren't going to see any gains. Not to mention you need a tuner.

 

I live in a small town so that's not really a big deal

 

Like a dyno or a programmer

 

I better of with long tubes with or with out cats??? What would I have to by and how would you get around the o2/sensor

 

so you know.. if a professional tells you how... and the epa police stop you... they could also get into trouble..

and possibly there job. just saying.

that is how much you are asking. and for FREE.

take the truck to a race shop... they make racing cats... and a reprogrammer.
