i was looking at magnaflow off road cats, those are the high flows correct? how would i pick the right one, i think i have 2.5 inch piping and as far as the cats length how is that work out if its a universal cat?
any correct ways i should be picking one?

 

if you want to replace the 2.4 stock cat with an aftermarket cat, i think our stock downpipe is a little smaller than 2.5 inch...

 

why not just buy a bolt in dp with highflow cat?

 

i bought the zzp 3 inch downpipe with a high flow cat. best bet would be to do that.

 

go wit the c/a downpipe..best for the price...if u want to know the specs..hre they are

2.5piping from magnaflow
flanges by vibrant
cat by vibrant as well

no need for 3inch if not turbo or s/c 2.4..go wit 2.5inch

 

Will a hi flow Cat cause the CEL to come on??

 

well from what I've seen before most get a CEL but a few don't. I think if you get one you can take it to the dealer and have them clear it for you.

 

you souldnt get a cel from a high flow cat,.i have put 2 on my car and never got one

 

ok the down cat is on the exhaust right? ohh and how about the garage that put my exhaust on didnt use the gaskets and i have an exhaust leak now? should i call up ARK and see if i can get 2 new gaskets? grrr i hate garages ( only reason i had them do it was i wanted my stock exhaust in one piece....yeah they cut it...i could of done that....) now im all flustered..

 

i didnt get the cel..once i broke it in...around 400miles..boom cel...lol. hptuners will take care of that problem.

 

Um.....you HAVE to cut the stock exhaust to get it off.

 

Your catalytic converter is part of the downpipe, between the exhaust manifold and cat-back exhaust. You have a resonator and muffler too. If you get a CEL some people are getting rid of it by using 2 spark plug anti-foulers (search for the threads on this)
