What dize of Hi-flow cat do i need to buy for my car? I have a 2.2l cobalt with a magnaflow catback and I decided to get at magnaflow hi-flow cat but dont know what size. (length, width, inlet/outlet)

 

no one has an aftermarket cat?

 

just go to cobalt-addiction.com and buy one...theyre all made for the cobalts...make sure you buy the one for the 2.2/2.4 though...dont wanna end up with the 2.0 one

 

Gravana has magnaflow ones DO NOT go with the 3 inch one I have it and get CELs from it at least once a week. I'm sure the 2.5 would be perfect I passed PA emissions testing with it so its working the computer just doesnt like it being so big.

 

so should i go with the 2.5 or the 2.25 inst the stock piping 2.25? would the 2.5 fit?

 

If your gonna throw it in you should get all the piping swapped out to either 2.5 or 2.25 i know the stock piping is really narrow less than 2".

 

io have a magnaflow catback so its different piping

 

the stock piping goes from 2 inch down to 1 and 3/4 so i would go with a 2.25 cat if u got the magnaflow catback b/c isnt it 2.25?

 

here is what you should do, ... first go to a autopart store and get some pipeing.. 2.25 inch get some bends and ****.. get a welder, and get a cat.. 2.25 in and 2.25 out.. than take out ur stock cat anc cut both flanges off it RIGHT AT THE SEAM.. grind them down, construct ur self a new downpipe with the high flow cat in place anbd weld the 2 flanges on to the new downpipe and cat... or if u feel really lazy and dont mind spending like 280$ go to cobalt-addiction.com and by a downpipe and high flow cat..

 

yeah, just go all out and get the downpipe w/the cat in it. better gains than just a cat.

 

Will the downpipe from cobalt-addiction work on a 2.2l?

 

i cant get to CA on firefox otherwise I would look at it and see.

 

...i can see it with firefox, and if thats ther only issue, then use Internet Explorer...its on your computer...unless your running a Mac

 

I took it off.
