All the white smoke and smell is the chemicals burning out of all the new pipes and headers from the welding. It should go away after a half an hour or so of constant running.
Remember to re-torque the headers after about 100 miles.
And NO it sounds nothing like a "ricer". Almost like a V8 but not, it's pretty unique sounding IMO. I have DTLT headers, off road Y pipe, and magnaflow system. Sounds best at 3500 plus RPM. Nice tight quiet rumble at idle. Hardly noticeable even without the Cats.
The dtlt, urd y, urd 3" exhaust has terrible rasp n/a imho and many others.
what magna system did u get?
Mine sounded like it had a massive fart can on a civic imho.....sounds like u got a better muffler.....size/part # would help others possibly
I know with the urd 3" system, many ppl run 2 mufflers or a resonator.
Do u have sound clip?
