Glad you made a video on this 🙏🙏
I believe the measurement should be taken at 45 degree angle from the end of can, now you pointing straight to it
This was taken at a 45degree angle. It is leaned against the back rest of the stool. Straight down would’ve been lying on the seat.
Cool test. Interesting that the perforated tubing seemed to quiet it the most.
Sound is most likely scattering all around the muffler much more, dampening the sound/db.
@@mikee1216 That makes sense I guess. I have the Akrapovic full system and now I'm thinking I should drill holes in the insert. I dont like super loud pipes but I do enjoy the massive performance gain.
@@chickentuber my full titanium exhaust only yields about 1-3 hp, not worth a ticket in SoCal. That is why I did the db test. I only wanted it for more smiles per miles cause the stock sounded too much like a seeing machine. I ride around the city and to work.
@@chickentuber which akra did you get? It came with an insert? I thought that akra racing did not come with one?
@@mikee1216 I have the one for the zx25r but it deletes the cat for better flow. I had the bike reflashed and I'm getting 72.9 hp at 14k
Nice. Looking for a DB killer for my r77. Any of yours for sale?
Any of what? The DB killers?
Yes but you inspired me. I ended up buying a cheap copy and got it turned down at a local machine shop. Works good but machining doubled the price.
So bro it can be legal in India? India got 80 decibel limit . But still we can keep till 95 it' can be considered till 95 . So it' legal in India ?
Yes, you should be good. I think this is legal in Japan, JMCA.
