X-Pipe and Secondary Cat removed... Video
I've had an x-pipe in place of the stock resonator for a few months now but always felt like the car could use a bit more. It was very mild compared to stock. Last week, I went back in to remove the secondary cats.
The car is louder, yes, but when driven normally, the increase in noise is hardly noticeable. Get a bit spirited on the throttle and the car is definitely louder. Some people may think it's too loud, but I like it. WOT sounds great! The initial start up growl is loud enough to make people jump. Cold starts are quite loud, but that only lasts for the first 15 or so seconds of the day.
The video doesn't quite do it justice, but this is just an idea of what an xpipe and secondary cat delete sounds like.
