Got an EPA notice

[adam69]

Well the bad luck just keeps on rolling in.I knew it was coming as i was stared at by a cop a few weeks ago and told the missus i would get a letter.Now all i have is a redback 2 half in cat back with no rear muffler.Any advice would be great.

[Jesterarts]

OPTION 1
go to exhaust joint and see if the got a stocko exhaust they are willing to throw ur way...
OPTION 2
Get a resi...

Good Luck

[adam69]

Thanks for that,i will see my exhaust guy tomorrow and see what he has.The more this car pisses me off the more i want to sell it.

[Spaced]

Was the issue the noise or the fumes?

[adam69]

On the letter it stated that the cop noticed that my car was loud,no fumes or smoke issues.

Just drop an extra muffler in and have it db tested. Piece of cake. Even have it tested before hand, it may be fine.

[AirStrike]

Option 3 like I did, put some restrictor plates behind the cats Dropped my car from 98dB to 91dB........which is still a fail but the dude put it through for me.

[adam69]

I sold my rear tail pipe with muffler in it to another member a while ago.I will need to do my cat too.

[crazywog]

yeh u cant have over 90db's i heard from EPA. that sux eh well good luck with that mate let us know what u get

[minux]

Actually, you can't go over something like 76db drive by. Not sure of the standards, i know it has come down 2 db though.

which is illegal.

1. get a stock V6 zorst and custom make it to suit ur cat back. (prob the best thing to do cause you can re use it)

2.get a sound control. pretty much a butterfly valve u can open and close. my mates got one is his car.

Your option 2 is just as illegal..........

And a ****load more work. Might aswell just go With your idea of baffle plates, i should pos a pic of mine, 7 or 8 5mm holes drillled. Boy did it feel like a 3 cylinder chirade on the way home

Yeah think mine have around 10 x 4mm holes in each plate. Mine wouldn't rev past 4000rpm, too much back pressure

[Torquen]

whats the legal DB level??

[AirStrike]

90dB tested at 2/3 maximum operating RPM.

[RockyVX]

pick up an oldie from the wreckers and slap that on there for your tests & DB Cert.

Put on your good system (cat back) for "Race days"

Depends on the exhaust, for the likes of mine which was hand build on the car there was no way in hell I was taking it off!

dad took his corvette over the pits yesterday and one of the things they knocked it back on was being too loud. it was 94dB with (what i understand is a) stock exhaust

Problem with imported cars, US have different regs.

[xlr8_87]

i think i'd need another one or 2 resi's (got one muffler one resi) to be under that DB level

[adam69]

Well i havw organised another cat and i will have a stock tail pipe and muffler fitted to the car for the testing.Spoke to the tester and told him what i had and what i was doing to sort it out and he told me that when its done book it in and he will test it.Straight up he said that only one muffler would not pass.
Im pretty sure the limit is 90db but i cant find the paper work at the moment.
Soon as its passed the old rear pipe will be giong back on but i will keep the legal cat as the one on it now makes it sound crap.

[Troy711]

Problem with imported cars, US have different regs.

its also too low (94mm to the lowest point)

[adam69]

Checked the paper work and the db levels are pre 1st Nov 1983 96db and after 1st Nov 1983 90db.

wont disagree with you. but when my mate was gettin his EPA off (he put a V6 stock exhaust on plus hes got a 286 cam so the car in lumpy as f***) an as they were doin the test he switched off the car walked over to my mate and said "you better of not put plates in her" and checked all the flanges.

And a ****load more work. Might aswell just go With your idea of baffle plates, i should pos a pic of mine, 7 or 8 5mm holes drillled. Boy did it feel like a 3 cylinder chirade on the way home

it is more work in some ways, but when my mate got pulled over he just flicked the switch and it sound like stock car and the cop didnt say anything. so in the end it saves u time of gettin EPA's and then puttin restrictor plates in and gettin the EPA off.
