Hey... I just got all the parts for my full exhaust. I just want to know of going catless is worth it. My plan is just to get another piping with oe cat when the emission test is due... high cat i don't know much about them... input pls thnx!
 
I would recomend putting a resonator instead. When I ran without a cat (non turbo) it sounded a little ricey.
