So I got a used CIA catted dp. Want to gut the cat but don't know if the bulb where the cat is will cause any problems with turbulance or what not. The dp is 3" and the larger part where cat is, is about 3.5". Opinions please.

 

meh.. I don't see how it will matter.. I think should be good... you're worried about turbulance from goin from 3"-3.5"-3"? do you have a 3" exhaust after the dp?

I don't think it'll be a problem at all... if you're worried, sell your catted CIA dp, an grab a catless one brand new for cheaps

 

Cut the cat out and weld in a straight 3" pipe...geez..lol

 

Tryn to avoid that^ My mig is a pos

 

lol..well pay someone $50...ha

 

F it. Guess I'll just sell it and buy catless. Much rather have a clean looking rather than one that's been chopped up. Thanks for the opinions guys.

 

good choice..get the zzp with the extended o2 sensor bung...

 

Punch that sucker out and forget about it. You're thinking to hard about it buddy.

 

Haha yes. I am often too analytical.
