Punched Out Cat
 

Hey.. gotta question.. I punched out my Cat Conv a few months back.. i already know its throwing the code.. but it was throwing it before i punched the cat. So i think its the O2 Sensor.. anyways... Will it sound too loud with the Pacesetter Cat back Exhaust

OMG i thought you meant a real cat....wow...

lmafo... i wouldn't do that

Put a High flow Catty back on.

thanks

Well, if you don't. Ion's Gonna chew you out. lol. I'll spare the details, A regular cat doesn't do much less than a High flow cat, but the High Flow catty can't hurt.

You're probably making less power will a hollow cat than having a cat on, plus you're polluting the air. And yes it'll be loud with an aftermarket exhaust and no cat.

well.. i punched it out cause it was clogged.. and i don't have the cash just yet to get a high flow.

high flows are only like $50

lower catalyst efficiency below threshold before and after? my guess is, if it was throwing it when you had cat on, somethign was wrong with the cat....i remember going through 3 in a 3 month period because something kept causing the cat to not filter, it was wierd
