One of the many suggestion I've been receiving are: bigger exhaust from the turbo to the mufflers and removed the mufflers. I get the bigger exhaust, but removing the mufflers, which one are they. I see two kidney looking mufflers one on either side of the car and then a big round one at the end. On a normal car (gas) the round one at the end is a resinator for quiter car and mufflers is before that. Is it the same in this case, the two kidney item are mufflers and the round one is a resinator? Thanks in advance.
