Hey guys it's my turn to have the rattles...broken cat

So I did some searching...can the M271 do the universal cat from magnaflow the 46004 so cut and weld

OR

Do I have to get the entire cat with piping?

Please give me some input on what to get please? Most results are for 2002 coupe so the M112s

Thanks

Maybe a good excuse to upgrade and pickup the Kleemann combo.

I actually dont know the info was from another member with m112 so maybe its the 5000 series but the thing is where can i get one of those universal cats and if our 1.8 engines can swap out the cat...from the sites i looked at they are all just selling the one piece pipe with integrated cat...rattling is driving me crazee

So I had the cat changed out today to a high flow CA cat...but i am still getting some rattles the guy says it might be my O2 sensor acting up...what do you guys think?? do you think I got ripped off maybe my cat wasn't the problem they never gave me my stock cat back

u should have asked for your oem cat to inspect the rattling...now ull never know lol..sucks =[
