Okay about 2 months ago I had got the dodgy exhaust system one of the previous owners put on ripped off and redone.

2.5inch, high flow cat, 1 resonator. But I left the cannon on it because I couldn't afford anything more at the time...

Obviously the thing to too f**king loud, I didn't really care and got used to it. Clearly the cops didn't.

Today I got pulled over, yada yada, $88 fine and EPA will send you a letter in a month.

The plan now is to rip the cannon off and throw on a twin tip muffler. The question is, will this pass through EPA? (Provided it is under 90db).

Thanks in advanced.

EPA emissions? that is the letter in the mail one? they dont look for noise just the emissions the car emits defect for exhaust noise and having to go get a check to make sure its 90db is the one you should hope it is? should be easy to pass if it dosent you need another muffler or resnator in it

90db isnt very loud at all, one resonator and a twin tip muffler is wat i run and i dont think mine would be under 90.

best bet would have it tested somewhere... judt dont know were ud dtsrt

"... the vehicle bearing Registration Number XXXXXX is excessively noisy and therefore likely to be exceeding the legal noise levels for the vehicle..."

"The noise test and anti-tampering inspection must be undertaken by an EPA approved Mechanic by the compliance due date which is Wednesday, 23 May 2012"

"- the engine test speed for your vehicle is 4800 rpm and the legal noise level for your vehicle is 90 dB(A)."

Again, I have a stock standard RB25DE with a K&N high flow panel filter, and a 2.5" exhaust system with a high-flow cat and 1 resonator + cannon (Will replace shitty cannon with twin tip muffler, hoping for less than 90 dB), stock extractors.

Will that pass the test? I'm just curious about the 'anti-tampering' part of it. Is a high-flow cat considered to be 'tampered' with?

Thanks.

would put money on you not passing with your current set up, my guess would be 97-98 decibels.

if you could get away with the plate that would work (again asking as they didn't see it. perhaps place behind the cat flange with 5 1cm holes drilled in it and only make the plate 1-2 mm thick)

*not sure on how many holes lol

Been there done that when I was on my Ps lol..

Best thing to do is borrow a standard exhaust from someone on the forums (heck im sure someone will lend you it for a day in exchange for a case of beers).

- Take off current loud exhaust

- Put on standard exhaust

- Go to EPA

- Pass inspection

- Put back old exhaust on and return borrowed exhaust

Your looking at about $50 for a case (depending on what your buddy prefers :P), $60 from memory to take the test and the $20 or odd you will be spending driving to pick up the exhaust and drop it back off.. Still adds up alot cheaper than paying a couple hundred and getting a whole new exhaust fabricated

      High temp brake fluid?

      By robbo_rb180 · Posted

      I use the penrite 600f in my cars and have had no issues even at Townsville v8s when I drove that but I bled fluid end of day for just in case. Good value and a about 38-40 on sale. Use castrol srf on the supercars and no need to Bleed brakes over a race weekend. Do the 1000km with no issues. Over 120 a bottle I seen at repco. A quality brake pad is always a good starting point the ebc stuff I've seen let go after 2 sessions with heavier cars. I'd be going to a decent track pad and maybe those porsche air guides on the control arm to help with some air over the rotor. Helps on 86/brz with stock callipers.

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣
