As long time readers know, my car served as the rig for the Tomei Expreme Ti titanium exhaust. One nice thing about offering my car was, I became one of the first (if not the first period) to have the commercial product installed on my car.
The exhaust is a masterpiece. And, if I owned my car out in the countryside with the closest neighbor a good kilometer or so away, it would cause no problems.
Unfortunately I live in a Yokohama suburb where I have neighbors to my left, right and across the (Japanese sized narrow) street. This means that every time I start up my GT-R, people notice. It also means that, if the Tomei is unbaffled, the noise is loud enough to wake the neighbors in the early morning or at night.
Clearly, I needed a solution, fast. Initially, I simply used the bung that came with the Tomei. That, along with the Blitz E-ESC electronic exhaust valve, worked for awhile, until that eventful trip to WORX where somehow that bung came loose and was lost somewhere in Chiba.
So when I got the car back, I managed to park the car with the Blitz valve fully closed, but herein lies the problem. First, the valve is designed to close only when the engine is warmed up. That means that normally, starting from cold results in huge noise (ok, music :). Second, I have to remember to manually close the valve to override the initial programming, which is probably not good for the engine. In other words, a bung should be used, with the Blitz valve being a back up when ultra-silent running is needed. While I could simply re-order the Tomei bung, I recalled a conversation with the guys at Nissan Prince Tokyo Motorsports about a superior product that was available from a third party.
A bit of research and I found this guy. Mr. Suganuma and his company, "SFC" (Suganuma Future Creation) - dumb sounding name, but very nice products, mostly all exhaust related. I was interested in his "inner silencer" products like this one.
They come in different diameters to fit different aftermarket exhaust tips, and two color choices - the silver as above or anodized black. What's nice is that you can order the component parts separately, so if you lose a part or a part (like the muffling part) gets burnt/worn out, you can bring it back to "like new" condition quickly and inexpensively.
So I placed an order for a black anodized one in 112mm size (product number 117BK), and a few days later...
|Cute, I guess?|
|The packing material is covered by silver colored paper (to protect during shipping I guess)|
|Of course, me being me, I have to clean out the inside of the exhaust tip before installing.|
|As you can see, it's a bit of a snug fit.|
|But of course, like most things Japanese, quality engineering means it fits perfectly!|
|Comes with these bits.|
Ok next post will also be about a non-WORX issue, something I've been tinkering with for the past few years actually... stay tuned!
