does an open decklid make your car louder?

[wolfswest]

Yesterday it was a beautiful day here in Belgium and I took my car for a spin...  I don't mind the sound of my ida's but I guess the people in my town and especially the cops don't like it.      Because there are many ricers  in my town the cops don't like any modified car...  So here is my question:  My decklid stands open  (the lower end not the top of the decklid)...  I guess that makes my car louder in a drive by @ high rpm because you can here the IDA's better...  true or not?  Would my car be more quiet in a driveby with the decklid closed?

Interesting question. I would say probably a little louder, but most of noise will get out through fresh air intake grills under rear window anyway. And if you silenced carbs you'd have the "whish" sound of high lift valvetrain at rpm, and roar of muffler(s).

What about just keeping a light foot on throttle in town?

Agree with Jim,do you run straight cuts,those will sound harder too,haha

let those IDA's scream !

yes, I try to keep my foot of the right pedal when I'm in the center of our town but it was just a tought if the decklid could provide me a more "sleeper" modus... 

but it is ow so difficult to not punch that right pedal to the metal and let those bastards scream like hell when you pass by some people with a big nasty smile on your face...   

I'll try to keep myself low profile because I'm running "O-plates"...  But that is something only here in Belgium so hard to explain for you u.s. or other guys...

i'll explain it:

O-plates are the ones for Oldtimers only. you don't need to do the MOT anymore, they don't check as much as a regular car, but you are not allowed to drive it as a daily. you can only drive it in a radius on 25 km around your house or to meetings.
so get that photoshop working to make some fake flyers for longer trips... 

as for the noise it won't be much more. and it doesn't matter as if people think it is too much with the decklid open, it will still be too much with the decklid closed. if you don't want to upset the neigborhood, there is a nice electric honda on the market...  otherwise get used to the angry faces. AND the smiles of people who do appreciate it.

   thx for the explination, I was too lazy for it!     I wouldn't go for the electrix honda because most of the import lovers here drive honda and a honda isn't lovely for the cops...    these bastards rev there engines like they think their drving a motorcycle...   

they didn't pull me over yet and I'm planning to keep it this way...  we will see.  And if they do I will go for the explination:  hey mr officer, it's just an oldtimer not a vtec...
