Neither this car nor this thread are dead... I just haven't been up to much since it has been unlicensed since late May. After months of ignoring the car's minor quirks, I've decided to restore my interest in it and look to start driving it again full-time I think. I think I will likely give/sell the grey B3 car to my sister as her first car once I'm done playing around with it, and start making the B6T car more tolerable for daily driving... which will be some effort on my part.
First off, the car is filthy and a bit smelly. I haven't washed it and the sap and grime buildup was growing to be too much, so I did a full scrub and wash on it with both car wash and heavy citrus cleaners to get it clean again. I then instantly remembered a few of the little issues and quirks the car was having. The wash revealed some neglected bumper paint that I will need to touch-up and re-coat... as well as a drip/leak I was neglecting through the roof and headliner at the driver's front corner. I sealed the roof-line up with some contact adhesive Goop I had lying around, and dried that up with a heat gun and a mask. Good as new! Gotta love free fixes.
So I will steam-clean the interior again completely. I've found that boiling the water in a kettle before putting it in the steam cleaner really helps the upholstery cleaner and wet-vacuum system to fight grease, and I can pre-treat everything with heavy cleansers to help loosen and dislodge any dirt in the seat covers and such. That should take care of the lingering smell from lack of driving.
At that point, it should be just about ready to go. However, before I get started driving it... I need to deal with the sound level from the tailpipe for the sake of my hearing, my neighbourhood, and my girlfriend. I have a full turbo-back 2.5" system complete with a ported O2 housing, high flow cat, giant resonator, and full muffler... but it's still too much unfortunately. While it may not be properly calibrated, I have a free app for my phone that measures sound pressure levels relatively accurately.... accurately enough for before and after testing that is. Here are the numbers I came up with for the car:
Car off interior - 41db
Car on interior - 72db
Car on muffler - 92db
By comparison, the stock grey car put out the following:
Car off interior - 40db
Car on interior - 70db (warming up)
Car on muffler - 83db (warming up)
Police officers in British Columbia are not armed with SPL equipment, and supposedly the legal limit for light duty vehicles is 83db. Obviously, my gauge is reading quite high then considering that a stock exhaust car with a brand new muffler clocked out at 83db just an hour ago. Either way, it seems like they only really enforce the legislation sections affecting those modifying or deleting mufflers... mainly on big trucks, hot rods, and bikes with open headers and huge pipes. That said, I have to reduce it anyway for my own sanity on longer trips.
So how exactly can I quiet down the muffler that I have? There seem to be two popular ways to quiet mufflers without replacing them... either stuffing the pipe with coarse non-flammable stainless pot scrubbers, or fabricating a collar sleeve that slips into the pipe and reduces the outlet size with perforated holes and such a little. I'm not sure which one I'm going to try yet, but I figure I can fab up both and compare how they do for under $50. Obviously you have to be smart with it though... because just stuffing your muffler with regular steel wool is a stupid idea. Not only is it flammable with fuel vapors and high heat (it burns with a propane torch), but could clog up over time with exhaust soot and cause major engine problems.
