Exhaust Volume

[XXpl0Sive]

Thanks guys..

Really, fueltank, your car's under 90db? The engineer was giving me the impression that factory turbo cars were already on the verge of 90db.

Poid, I'm borrowing a stock exhaust and putting that on so hopefully this works out. Does anyone have jackstands or ramps I can borrow overnight?

Danny, it's a blue slip, I need to get the car in order before Thursday..thanks anyways!

my car is under 90db Ben.
I think they rev it @ 1/2 or 2/3 of your car's peak power from factory.
Testing needs to be done in I think a 3m by 3m square with the db meter @ a 45 degree angle.

I got the PDF of ADR procedure on measuring exhaust noise somewhere.

I can't remember to be exact, but it's about 2/3's of your redline. For example, my wrx redline was 7000 and they tested it at about 4,500rpm.

It's not from your redline, it's from your 'peak power'

Ben, I got jack stands.

hay boyz all ive done in the past is make a restrictor plate. what that is, is imagin a plate with lots of little holes in it. it maks a big differance. and with price to get a db test should only cost about 60-80$ [/quote]

you can drill a little hole in for the silencer, done
add a resonator... change your exhaust....
