Thread: catless down pipe

so wondering would you get better gas mileage with a cat or with out?

97-00, it wont matter.

what do you mean?

because i just put a 2 1/2" catless DP on my car didnt really drive it much yet so im wondering if ill see an increase or decrease in gas mileage

It will not decrease, slight slight increase. Don't do it just for mpg's.

97-00 cars dont use the rear o2 for fueling.

it will help with flow though.

i already have it on and im not doing it for MPG's lol im just wondering if i made a mistake or not with no cat, inspection isnt a problem thats not why i work at a shop but i just dont want gas millage to suffer
