Can i Kill Some CAT's

2002stang · October 8th, 2008, 10:43 AM

my question is Can i kill 2 of the 4 cats on my stang??? My state doesnt have emissions, and ive heard people saying that getting rid of 2 of the cats makes it a little louder. By the way my car is a 232 V6 with 2 1/2 Catback flow 40's with and Hpipe crossover and 3 inch tips. It has a cold air intake and PP upper and lower intake. I currently have a xcal tune on it with 4:10 gears and i usually run 93 octane.

hey let me know if u get any info because from what i have researched and talked to some shops is if ur looking to get louder feel free to cut out 2 cats but u may loose some TQ but loosen TQ dosent matter if ur not a seriouse race and MOST ppl are not lol but i hav a 1994 stang and i have 4 cats two are visable when u look under the car and two are hidden more near the headers so im thinking if i can ill cut the hidden ones out so if a cop or when i go threw DEQ when they look they will see 2 cats

correct and correct

cutting off your cats will not make your car as loud or gain as much power as an offroad pipe
