OK in the past 2 weeks ive been defected 2 times.First time was for blow off valve.

Second time was for exhaust and my HIDS.

The first copper said my exhaust was fine but not to go any louder.

The second copper was a prick and wrote me up anyway.Today i went to get it tested and i was 4DB over(shit) so i went and got a standard exhaust put on.But the thing is i have to give it back in two weeks(loaner)

Seeing as my other exhaust was only 4DB over what can i do to it to make it quieter without comprimising flow.The standard system has robbed so much power out of my car its not funny.Can anyone in the same boat help me out?Options? Is there quiet high flowing systems on the market?

CHEERS

I guess ill have to try the centre muffler option.Going from high flowing to standard exhaust is a huge decrease in power.Amazing what a high flowing exhaust can do for turbo cars.

yea bud the best option is to get another centre muiffler as the others on here have said... the hks super dragger exhaust i have has a centre muffler and a hotdog aswell... its pretty quiet so that should do the trick for ya

My one is a fujitsubo.the guy testing it was suprised that it was over cause its pretty quiet.The standard one i have on now is 88.5db. My aim is to find a system that is 90db but provides the same flow as my fujitsubo one.There must be a market out there for legal yet high flowing exhausts.

Now on the subject of defects.I have an intercooler in the garage ready to put on.Are they a defect.A hole has to be cut into the engine bay to fit it.

If you're cutting a hole in the engine bay you're going to have to get that engineered, otherwise = defect?

(Going by what happened to a friend of mine)

Go to Mr. Muffler - get a Muffler that's within the legal DB limit - get the guys to write you up a report stating that it's legal - make a copy of it and keep it in your car...

When a copper pulls you over - show them the paperwork and that will shut him up.

That's what I've found...

Simple get an exhaust that complies.

There are some made by kakimoto and fujitsobo that are legal.

they have a 92 or 96 suffix on the model names.

can't just get an exhaust that applies, it needs to be engineered to say that it comply's with the australian design rules.. i was defected for my exhaust, and mind you my exhaust is under the dB rating.. i was told that if i didn't have a engineered certificate to say that it complys with the australian design rule then they can keep defecting me..

simple answer: Either know someone dodgey to clear it like i did... or put the stock one back on.

This is true. Although, if you are defected for noise - my solution would suffice.

If you are defected for no ADR compliance - your solution would be the only one.

    • Surely the merged entity will be called "Honda" given the relative company values. I've got to be honest, I don't understand how merging 2 companies that missed EVs (despite Nissan making the first mass produced one) will solve their problems
    • If you haven't bought the ECU yet, I would strongly consider buying a modern ECU. Yes it is very easy to setup and tune, however it is lacking many of the features of a modern ECU. The pro plug in is something like 10 or 12 years old now? Can't remember exactly but it is very dated now. In that time the Elite was released and now we have the Nexus platform.  I would strongly consider not buying the ECU that is 3 generations old now (especially as it isn't a cheap ECU!). 
    • Im happy for it as long as it means reanult gets the boot 
    • Sorry I should have been more clear with the previous post.  The block is a sanding block - picture something like this https://motorguard.com/product/motor-guard-bgr161-bgr16-1-rigid-psa-sanding-block-2-5-8-x-16/ The guide coat is the paint It's two separate things I was talking about, there is no "block guide coat". 
    • Maybe more accurately, you aren't just dulling the existing paint, you are giving the new paint something to 'grab on to'. By sanding the existing paint, you're creating a bunch of pores for the new paint to hook on to.  You can lay new paint over existing paint without sanding it, might last a year or two then sad times. The paint will peal/flake off in huge chunks. By sanding it, the new paint is able to hang onto it and won't flake off.  Depends on the primer you are using. When you buy your paint, as the paint supplier what grit of sand paper to use before you lay down the primer.  Use whatever you like as a guide coat. Pick a colour that really stands out in contrast to the paint. So say your sanding/painting a currently white car, using a black guide coat would work well. You very lightly lay the black guide coat down, then as you sand the car with the large block, all the high spots and low spots will stand out as the black paint is sanded off (or isn't sanded off).  When you buy your paint, hit up your supplier for recommendations for what paint to use for a guide coat if you're unsure what would work well with your setup.
