He likes going slower and running the seals into useless pieces of metal overrevving like that

The old JIC Ti exhaust was lighter (under 10 lbs), less expensive, quieter, and sounded better at full song imo. But those days are gone forever now ...

Diyman25

Thanks ~ the unique merge make it sound different and nice

Because car is faster let's why I bounce rev limiter , and u try to film it in bumpy road !!!!?(???)

Never like JIC now , I did use JIC ti muffler on my 13B PP long long time ago
but the muffler brake into half from their weld
At 30min of track used
Happend to run into the JIC owner at one event
Show the muffler to him , the way he treat u
Make u don't want use his product no more

did you use the expansion chamber pipe?

Diyman25

I think Re Amemiya no longer make expansion chamber version,

According to your last dyno graph, the power peak was at 8,100 rpm. I’m just trying to make sure the dumdums on here recognize that revving to 10k may seem cool, but the car is accelerating a lot slower than if you shifted at 8,500 rpm and it’s also killing the side seals on the engine rotors. Just because it can rev that high doesn’t mean you should. I’m a racing situation though, it can make sense to rev it out rather than up shifting and then almost immediately down shifting. Racers tend to be more accepting about the cost of rebuilding or replacing an engine.

oh well,
stil the coolest rx8 muffler around,
I was going to get one,
but then a ( rare in AUS) racinbg beat rev8 came up cheap

Diyman25

Buddy come down
I know The consequences about rev psss 9500
. At track I shift at 9000rpm
To help my side seal, i premix In tank , injection more oil from omp, and even stop the fuel cut if rev pass 8500

Diyman25

Cool racing beat get one of biggest piping compare tonJDM one too

Calm down yourself. I wasn’t talking about you and thought that was clear. Maybe it was just lost in translation.

The idea isn’t new or unique, just overly complicated and unnecessary **imo**

When u mention my dyno sheet, I think that is talking about me, any how not really important


Well is hard to say who come out this idea of merge first , but most of time is Japanese tuning shop did
So others country vendeor just took their idea
Try to improved it or copy
My point is not say the Amemiya one is best or not, just say compare to my Rmagic catback
I like Amemiya one better

I was just using it to make the point. It was also your car with you in the driver seat revving it out to 10k

Diyman25

Ok la
Thanks for head up
But thread is about how sounds of Exhaust
