Straight-through, dual, single, and cannon-style mufflers
Mr. Kawate from Gakudori's OB group made me a muffler for Nikko! It was an unbelievably cheap 3,000 yen from the flange back, and it sounds great above 4,000 rpm! It also stays within Nikko's noise regulations!
On the first day at Nikko, the editor-in-chief rejected my prized 50-cm extended dual tailpipe. So I switched to a straight-through tailpipe made by modifying an R32 catalytic-converter pipe. Then Koguchi said it was too loud. The next day I finished the event using the 110-mm cannon-style tailpipe I'd brought just in case.
A loud, straight-through dual tip for Tsukuba, then a cannon-style muffler to meet noise limits. He carefully progressed through each step…
Comment
I wanted the one-off Kawate Shokai muffler featured in the January 2012 issue of Drift Tengoku, so I asked a senior to introduce me to Kawate and commissioned one…
Comment
The fact that he carefully made it in stages shows his commitment to student drift…
…nice work!
That's what he says. It's a simple muffler with only a rear section, but it's impressive that it was built specifically for Nikko.
I changed the plan midway because of Nikko's noise limits!

I built it to comply with Nikko's noise limits! It has a resonator, and I joined sectioned pipe at the outlet to create a dolphin-style tail. With all that, they won't stop me anymore. I made the straight dual exhaust myself too!
Homemade mufflers are common, but this is the first time I've seen one built from sectioned pipe!
Comment
He also added a secondary resonator near the differential…
As a result, the entire exhaust—including the manifold—was replaced, yet it still easily meets the noise limit.
I added a center resonator too!

I originally planned to have a straight-through muffler with four outlets made, but I heard that Nikko's noise limits have become strict recently, so I changed the plan during fabrication. I had them change the tailpipes to a resonated dolphin style. I'm grateful to Iwamoto Shokai for accepting my demanding request!

…thanks!

All the tailpipes visible from the outside are dummy outlets…
Comment
That's a clever idea. It looks good and performs well. The real exhaust outlets are cleverly hidden underneath, so the car doesn't look out of place.
