Ive been thinking about getting a pulse chamber [i have a tanabe medallion installed] to dyno both of them... anyone have one for sale.... msg me!!!

 

So I found this after some digging

OEM axleback: 4.1kg
HKS Silent Power: 3.0kg

2.2 pounds. Saw it on a youtube video where they weighed them and installed the HKS. which would mean the bisi axleback saves 5.5 lbs.

 

I installed an RV6 catted downpipe ahead of the pulse chamber. It is now rip snorting loud! The tone was low, aggressive, and controlled before but now unacceptably irritating and dare I say it Honda farty when on the gas. Going to have to put the stock muffler axle back back on for now. So I can only recommend the Bisimoto with the stock downpipe. It just really sounds too free flowing now its so loud. This is my review from inside the cabin. I haven't heard how it sounds from the outside yet and don't really care to.

 

If you dislike the bisi.... send it to me... ill pay the shipping!! 00680 is the postal code...

 

sell the bisi, and then buy my Buddy Club TI exhaust =)

 

Working on selling the Bisi. It was nice while it lasted but I plan on trashing the stock downpipe. Stock muffler is now back on and peace is restored. I may next swap the OEM axleback for a weld in Thermal R&D or Magnaflow muffler.

 

pure curiosity..... did you feel a power loss?

call me crazy but.... when I went from Bisi to Buddy Club TI, I felt a slight loss of throttle response, and a loss in the mid end

 

I would say it feels and sounds less responsive but is it really? The stock exhaust does such a great job of isolating us from what is going on with the engine. I've spent less than 30 minutes driving around with the stock muffler and I already miss the way the Bisimoto sang to me. Now driving is more of a task than an experience. RV6 Catted downpipe + stock exhaust on my 13 Si yielded a bassier exhaust note. Doing the same to the GK Fit yields no difference although it is probably a touch louder.

 

thank got i found this thread before buying anything..

i have 18 sports model as well and was about to make purchase ....

hmmmmm that hanger thing is pretty annoying.. i wonder why they made sports model little bit different like that? its not like sports model had any different attribute =(

 

I want to fabricate this one for my car,, is it just a small closed pipe welded to a thicker pipe?

Thanks for the measurement but also curious if it just a hollow pipe or things or technology is being used inside that muffler

 

I have a feeling there is a technology being used inside that muffler

 

PFM!!

It is hollow but uses wave cancellation technology to create the distinct sound. Bishi is a smart dude and has some smart people working for him.

 

I might have missed it- but with the fitament issues- could they be caused by the fact that the people installing them had a cvt trans?
i see white a few exhausts that say "for manual trans only, not for use with cvt" so i cant help but wonder if those are the issues we are running into as opposed to year issues.

Im definately considering going with this exhaust for my 2020 sport 6mt

 

If only i were able to find one...... :sigh:

 

I have a spare helmholtz resonator ..... pm if interested. you can use this to make your own bisi exhaust

 

pm inbound

 

i guess i cant reply or pm now till mod approved...
