hey its not my car, I would at least go with a 3" with no muffler, that would be pretty much like an open downpipe…(since motor in back)
I was refering to when my car made 262whp it was soooo much nicer to drive with an open dp then having an exaust on it!
mufflers are for STOCK turbo cars…i mean if you wanna stay stock go ahead and put a “fart can” on it! 50% of the time the cans make it god damn louder!
