hi friends, as title say which exhaust system is quiter and better on r33gtst thanks need help asap.making 290kw.

I've been looking at the same options for my R32 and the Kak system was quieter out of the 2 but still had a nice note above 4k

  • 1 month later...

Slightly off topic but I have just fitted the Kakimoto Regu 06&R to my EVO and the difference in performance and overall exhaust note compared to the unknown Japanese system I previously had is very noticeable. There is virtually no drone at idle/cruise but the system has a phenominal bark when you apply the right foot :thumbsup:

im looking at getting kaki for my car from JJR, heard a few clips on youtube and sounded great, my zorst is way to loud and more suited for track

The Regu 06&R is one of our most popular systems at the moment for street driven vehicles.

You will not be disappointed :thumbsup:

I've got a Kakimoto Regu 06&r on my R34 GTT...

Performance

It is basically silent as stock (idle to 2.5k) and 3k all the way to redline there is a quality growl.

Put it this way everyone who jumps into your car will think you have a stock exhaust (without looking at it lol) before your turbo kicks in...

Looks

I looked at every catback for my car about an year ago prior to purchasing it... HKS/Apexi etc. All did not come up to scratch in terms of finish by comparison to this. Chrome tip as well... its almost silver/gold (the advertising style pics are a little deceiving) in color as well so if you have bronze/gold rims they will match up nicely.

I can record the note from my exhaust to my phone and upload it if theres any interest??

+1 for Kaki Regu 06&R

Have had one of these on my car for about a year now and it's a awesome sounding exhaust. Good at low revs and daily driving, but open's up great when you're giving it heaps.

Have heard from my tuner that the Trust PE II is quiet, because it is quite restrictive.

so it seems the kaki regu 06 is the better choice over the trust pe2 (im guessing both of these exhausts are stainless steal?) ?

i was wondering if someone could also answer this question:

atm i have a HKS hi-power catback, unknown cat, unknown 3" frontpipe... what dB would this roughly be rated at? how much would the kaki reduce the sound by (db) ?

just so i can get a comparison to see if its worth getting the kaki or trust or just staying with the HKS if its not going to change things much

    • @Haggerty you still haven't answered my question.  Many things you are saying do not make sense for someone who can tune, yet I would not expect someone who cannot tune to be playing with the things in the ECU that you are.  This process would be a lot quicker to figure out if we can remove user error from the equation. 
    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.
