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

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
