I have searched around on the forum, but I haven't come to any conclusion. I think that I have settled on Magnaflow cats, but I am not sure which ones to get. Any suggestions would be great.

I do plan to eventually go to true duals. Right now I have a Cherry bomb cat back SI/DO coming out in front of the pass side rear tire.

 

most people on here go with magnaflows part #'s 94106 or 94306 the first one is the louder of the two

 

x2, Have the rear O2 sensors mounted after them and you will be fine.

 

how long will they last?

 

there is a 5 year warranty on them

 

and what makes that first one louder? or how would any cat be louder than another? just hollowed out more?

 

Thanks for all the replies.That is the exact info I needed.

 

the first one i believe is a shorter body which makes it louder

 

Precisely . 94106 is 9"s long which is just enough for the catalyst, and both cats do not have any resonating filters.

 

doesnt magnaflow make a cat that has bungs already in them?

 

They do, but some people have gotten CELs using them, the O2 re-mounded after cat is guaranteed not to give a CEL. The O2 mount cat is part #94136.

 

I got the smaller cats from Summit racing. Ordered them yesterday and I already got them. Next I just need to find someone to put them on.

 

i guess i might have to get some of these as well... the neighbors are gonna hate me

 

Thats one of the best parts

 

Sorry if high jacking, if I go with 94106 will I need o2 extensions? when you say mounted after them, so that means before the cat on top?(closer to motor) or after the cat on bottom?
