OK So my Check engine went on, on my 2003 oz lancer it turned out to be a bad cat along with a sensor.... chargin me 800+ tax.....

my questions is

are there complete exhaust systems for less that could work and replace the bad CAT...

or should I just do the straight OEM swap???

 

i paid less than 800 for new headers, cat, and catback exhaust + 2 new o2 sensors.

 

^yea don't pay 800 bucks to just replace a cat, thats atrocious
