Let me reword my last thread that got locked...my cat clogged up on me a few months ago, and having school the next day and no money, i was in a pinch and just had to straight pipe it...however this increased my fuel economy...will putting a new, aftermarket cat on increase my mpg's?

 

As said in your last thread...if it was clogged..now it has more flow therefore will give you better gas milage. Putting a new cat on there after removing the clogged one would have also increased your mpg also.

 

thank you...but will putting a new one on now increase it?

 

Look at mudfrog, a vendor on the site. He sells a VERY good high flow cat that is legal.

 

Yes it will help.

Under the rules of your last thread closure, speeding, underage drinking, selling a used cat to another member, etc etc should all be against the rules.

 

thanks, i will definitely do that

 

Oh i understand that, i just didnt get the whole taking the cat off was "illegal" until i did go back and read the rules, i reckon that's just something to be left alone

 

check out our vendor mudfrog. I just ordered a cat from him. they start at $36 and the "highflow" is $59

 

i would replace your 02 sensors as well mabye just thro sum 15ohm resistors in there but putting a new cat on there will deffintly help with your air fuel ratio as well cuz of the 02 sensors

 

x2 on new O2 sensors

 

alright sounds good to me...i'll probably be doing all this after i get my new front bumper back from my friend who's doing a little modding to it...but after that gets back, bedlined, and mounted, i'll get some o2 sensors and a high flow cat from mudfrog

well i found him, but is his site listed or should i just pm him on some details?

 

did you like the way your straight pipe sounded?

 

hellllll yes, with and without muffler...if you've seen videos on youtube, they do it absolutely no justice...im of course running it with a muffler right now, pending buying a highflow cat from mudfrog most likely

 

it is on his profile. performance-curve.com

 

had the same problem, replaced mine with a stainless steel magnaflow. sounds so much better and the mpgs are alittle better, nothing too crazy though.
