Got on the horn with a vendor. Ordered the new Unitronic downpipe in Nov through [website], Unitronic sent a Mk8 one. Got a return label, Unitronic received it back but never sent the correct one, and no response to emails from [website] for 2+ weeks. Call them up, things get shouty, they put me on hold and call Unitronic, who couldn't explain the delay. [Website] told me it should ship out early next week. We shall see.
Hope the cast section and cat location of the Unitronic DP tones down the awful, tinny, metallic rattle noises I've dealt with with this Trackslag unit for the last couple years. The unholy things happening in these cars' cylinder heads around 3k RPM are not meant to be heard.
