i have a kakimoto stainless exhaust cat back, and it is surposed to keep the DB level of the exhaust down by 7DB i read. it came on the car from japan. its on an R33 GTST. it has a nice note and sound but its quiet enough to keep the cops off your ass for noise polution.

1300 is way too much money to spend on a cat back, i would not buy one at all.

instead i would buy a xforce stainless steel turbo back exhaust system. u can get them for 950 (not delievered, add about 70 i think for delivery)) including hi flo cat and muffler with adjustable silencer.

I agree

I got one of those xforce turbo back systems from ebay about 6 months ago. Full stainless for about 1000 delivered. great note and easy to fit.

hey is the adjustable part of the muffler removable altogether?

is there a big difference in noise/performance when u open/close it?

The adjustable part can be removed easily with an alan key - one screw.

As soon as I received the system I removed the silencer and have never driven with it on so I couldnt tell you from experience.

I reckon you would notice a slight difference in performance as the end piece would be more restricted.

It sounds great especially with the hks pod at the front.

:cheers:

The exhaust on my '33 has a blended dumppipe (seperate wastegate pipe, very neat), hi flow 3'' cat, full manderal bent 3''system, 7'' rear muffler ( look sweet) , silver ceramic coated dump and front section down to cat - all done for $1600 at exotic exhausts in Brisbane last november. Drive it in, pick it up in the arvo. Sounds a lot better, and even better, goes better!

Cheers!

Or one better, have a mate whos 4th year sheet metal apprentice and all he charges is the price of the 180degree mandrel bend :headbang: mates rates :rolleyes:

I just got my cat back 3" redone alot straighter and removed the resonater for $50 (used the old muffler, which needs to be repacked)

it pulls more at top end, ide say its gained a few kw compared to the last 3" cat back because it was very bendy and had an old rusted resonater

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
