we each did a quick driveby video after the install, I recorded his I just havent uploaded it onto youtube yet. But as far as I know his is working fine.
I had testpipes on my 350z and I got used to the smell that those actually made, but on this car I can honestly say I don't smell anything different (in case you are worried about cops smelling it at a stop light or something). Smoke wise I havent seen any, but I rarely look behind me to check.
