Even if it gets hit from behind…
No matter what…
Prevent a fire!
Muffler modifications
Protect the fuel tank!
Clever thinking solves a serious problem
…and assembled it from materials I had on hand…
…was troublesome to remove and reinstall…
The resonator…
…so I matched it with the silencer…
I made a tool to remove it…
Work…
The materials were a long bolt and…
…a part and some kind of bearing…
The stepped part of this tool…
Pull the silencer…
Hook it on and just pull
…and it comes out easily!
After using it once…

…convenience!
I can't do without it

With Silvia-type cars, if the exhaust gets hit from behind, the muffler…
The muffler bracket could pierce the fuel tank…
Hidehisa Kurata
Instead of removing the resonator…
…so I changed the bracket's orientation to prevent that…
…and it could shoot sparks or flames. To prevent that…
The muffler hangs down low, which is a subtle issue…

When you remove it, it's too hot to touch…
Comment
…or trying to grab it with pliers…
…but I think it's better to leave this in place.
…I do!
（S13）
…or there's nowhere to get a tool onto it…
Anyone who's experienced it will understand how frustrating it can be. This tool is…
It was very difficult to photograph, but notice how the bracket sits close to the fuel tank…
Comment
…with a few refinements—the second version.
…apparently an improved version…
…and protects the tank. Adding a part…
Changing the bracket's direction instead of removing the resonator is a clever reversal of expectations.
Relocating the silencer…
…ensures minimum ground clearance!

Extra-long…
Wool-packed version!
It looks almost straight-through…
…appearance…

An off-the-shelf inner silencer...
...the silencer alone is too loud...
...so I extended it by welding to quiet it down...
It looks that way, but it's actually near the differential...
...relocated to around the front...
...turns out to be a metal scouring pad!
...I wrapped it with material. The sound-absorbing material...
...it looks like a straight pipe...
...and at the same time, to reduce noise...
...and the result is spot-on!
...just wrapped it with wire, but...
The clearance is about 5 mm!
...to maintain ground clearance...
...for clearance between the driveshaft and...
This is also a proper...
The bracket near the silencer is firmly secured...
Stainless-steel wool!
...with clearance around the rear...
Comment
...so it doesn't look likely to interfere. TRA Kyoto's wide fender...
Because the metal scouring pad is stainless steel, it's extremely durable...
...the volume was fairly mild.
...and the straight-pipe look is really badass, but the sound...
...and its shape makes it perfect as sound-absorbing material. Two of them should...
Comment
Ultra-quiet.
If you're going for an aggressive look, everyone has dual exhaust...
Dual exhaust modification
Even a single exhaust...
...I wanted something distinctive, so I made it dual from the base...
With a catalytic converter...
That's the important part!
Kenji Takebayashi
...I made it! Material cost: zero yen!
...cut from one piece and joined into a single...

...you know, it doesn't get caught by it.
It's a straight pipe, but the RB doesn't get flagged for noise at Nikko...

Everyone's modifying theirs from single...

...I use a rear catalytic-converter muffler...
...I want to try street-legal competition, so at events...
...street-legal...
...but when converting to a single exhaust...
...that's a rare case. In the paddock...

...I use one. The catalytic converter...
...compared with a straight pipe...
It's clearly a straight-pipe sound, but...
...but on the road it stayed below 105 dB...

This leftover piece...
...it makes more power than in the stock position...
...the flow isn't great, but...
Does anyone want it?
...so power loss is kept down...
...a road-legal setup with the tailpipe not protruding...
...right? For street driving, it doesn't stick out...
Kohei Arai
A manly, sharply upswept dual exhaust!
...I swap it over to that.
Low power loss

Compete with a rear catalytic converter!
(S13)
...it feels lonely!
With a single exhaust...
It's a show car, so I didn't want it to lose its impact...
...so I went with duals...
Since the school is part of the Nissan network...
...given the team's lineup, it's a compliant setup...
Comment
...so I did that. Inner silencer...
...the silencer is two canned coffees...
...Takebayashi, who sticks to legal specifications...
...and in that process, a rear catalytic converter...
...I got a catalytic-converter muffler...
...with two ¥170 clamps...
...just hold it in place with two pieces!
...bly won't pass vehicle inspection.'
...but, for emissions testing, 'proba...
...it seems just right. It has never come loose with the clamp...
With a 60-size coffee can, the gap works out just right...

...according to him.
His friends even called him one of the 'Four Erotic Kings.'
