i was on rx7store.net and as i was doing a little shopping, i happened to come across the racing beat full exhaust system for the fc3s turbo. it claims to up boost pressure to 10-11psi and increase hp by 32% or +/-59hp. Does anyone have this exhaust system bolted on to their fc3s? does it actually increase performance by as much it says it does?

 

from learning how to use the SEARCH function, you could clearly see that there is already a thread covering this topic, but i will simply summarize the thread for you

basically thats what they claim, but people have only gotten about maybe max of 20-25, n thats probably even over-exagerating, you do gain i think a noticeable amount of power, after installing an exhaust system, youll notice that everything is better free flowing than how it used to be, just stick with racing beat for the exhaust, people on this forum trust it the most

 

YES.

Stock Zenki puts out 182hp.
With the exhaust, that's like 241hp.
Knock off 15% off for drivetrain loss, it's like 205hp on a DynoJet.

Stock Kouki puts out 200hp.
With the exhaust, that's 259hp.
Knock off 15%, and it's 220hp on a DynoJet.

These are the numbers the cars typically post with the exhaust.

BE CAREFUL WITH FREE FLOWING EXHAUSTS LIKE THIS.
We recommend running an FCD and upgrade fuel pump (+ verifying fuel pump voltage) when running such a free flowing exhaust.
