quick question, if i get a cold air intake and strip my cat's, how much of a sounds increase will i get with my exhaust, if any? thx guys. chuck

 

not much and a nice CEL

that should and WILL solve your CEL problem....

 

um

 

what does that thing do.....i dont understand.................that will keep the computer from throwing a code because there are no cats or what?

your truck aint junk zabeard

 

exactly.... its call a simulator, basically it tells the computer that the 02 sensor is there and everything is working fine....... its a big time must for mustangs and basically any new vehicale with downstream O2 sensors, that want to put a full exhaust system on....

 

so if i was to rip out my cats and leave my O2 sensor in i wouldn't need it.....so many questions because the emissions testing has been eliminated here in southern indiana

 

and if it comes back you will have to pay a fine. a cop could still pull you over and fine your for it right now.

i jsut dont see it benefiting a ranger, unless you have boost or are turning outragous amounts of power.

 

well see the problem with ripping your cat out and leaving the O2 sensor is that now the sensor is going to be reading off the wall becuase there will be more fuel going past it( since thats the point of a cat, is to trap all that crap), so you will need the simpulator to replace the sensor and then you can run open headers if you want, but like zach said there really is not reason what so ever to pull your cat, and also you remove your cat you will need to put like a flowmaster or a quality muffler in some where closer to the motor tp compinsate for the loss of back pressure that the cat produces....because if you just run straight pipe all the way out you will lose all back preasure and the truck will run like crap, so thats something else to think about.....

 

i hadn't really planed on taking them out i was just curious.........mine aint clogged and work fine....i might get rid of 1 since i have 2..........
didn't think about the back pressure....good call...

 

Flowmaster, Magnaflow, or Borla is the answer to the muffler questions....theres plenty of posts lmao

 

i have a dynomax cat back kit now

 

Sweet, i was being a smart ***...cause if u ask what kind of muffler you shoudl run youll get bombarded with answers....


BTW Hows the dynomax sound??

 

Run Magnaflow and a high flow cat and get rid of the other cat(s) and you will notice a HP difference...mainly on high end. Ive heard cold air intakes dont do a thaing as far as HP gains. Many will disagree with exaust helping out a stock engine...but in my truck it definetly helped. I Could have had some clogged cats (I had 2 inline) to begin with..i dunno...but it flows now.

 

The problem with Cats is the O2 sensor tells your truck to run lean or rich thus keeping its "normalicy". However if cannot make these corrections if you "bypass" the O2 sensor with a simulator. Personally I would just install high flow cats. If you ran straight pipes you loose low end torque, however you gain more high end horsepower then you would running any performance exahust. If you run at the track this is fine as you are never in ur low end torque range for more then a second or two. However going in traffic you'll notice a loss in peppyness.

 

My CAI can be felt in the low end more so than the top end.. its wierd because I thought it would be the other way around.

 

well im putn a flame kit on and i hav to strip my cats so i can get fuel back there. ok ill get that sensor. i hav a 40 series flowmster muffler, will i hav enough back pressure?

 

it sounds pretty good....not too loud but not quiet either.....has a nice little rumble to it....

 

I pulled my cats my truck still runs great.. Plenty of low end. can smoke the tires down the road. Why would u need any more torque ? Gas milage improved also. 24 mpg with a kn air filter. and no cats.
