I wanted to do a similar thing with my old N/A but ended up doing just a short pipe. (Cheaper and easier at the time). This setup is good, you could maybe shorten the pipe by getting it on more of a downwards angle rather than going all straights and 90 degree bends, but it's probably not that important. Some heatwrap along the whole length of the pipe might be a good idea. There will be people who say it's too low, aslong as it doesn't get hit by speedbumps then it's fine, just avoid puddles. (In the rainy months you can always detach the last bend and stick the filter on the end of there anyway).
