Dynomax super turbo catback for 540i
For sale is a Dynomax catback for 540i. Consists of a 3"OD mandrel bent pipe, Dynomax super turbo muffler 3" in /out, hanger and a clamp. System exits at an angle under non sport bumpers. System only used for a couple of hours ,still have box for muffler. This is ready to bolt on , slips right over the factory pipe. the only thing you would need is a turndown or muffler tip. Sounds similar to a magnaflow muffler, low,mellow tone. Flows similar to running an open pipe. Provided an increase in power mainly in the upper rpms. My Wife hated it! LOL .Will post more pics later today .Asking $75
