Being Sent To Epa, What To Do With Current Exhaust?

[S3RK]

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.

Cant see why it wouldn't pass

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

The old flange trick, Cheapest and easiest way.

lol,

flange

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

Might just try and save and get the twin tip on. I think it's the best option at the moment.

Keep saving and buy a "prius" Will save you in the long run

also cannons are for pirates, and full of the gheyids

"... 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.

just bolt a metal piate with holes drilled through behind your cat you'll pass no problems.

[Captain Natro]

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 ), $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

^^

Best idea you could do imo.

[S3RK]

Didn't realise I was running out of time so quickly -_-, just went and got an epa muffler attached temporarily. Sounds like shit, goes like shit. Getting test done today.

[Captain Natro]

post up ur db reading & exhaust specs at time of test, I'm curious

[bozodos]

please leave it stock for the sake of the ears of everyone ta

[Captain Natro]

pfft, natros = Raspy droney goodness

[Berk]

Don't you just ram a whole bunch of steel wool up there?

I thought that was the noise reduction convention.

Get a stock GTt rear muffler (assuming the pipe joints are in the original location). Plenty of flow for an RB25DE and quiet.
