the point on that post was that stock is quite....whats wrong with what i said?

 

you obviously have no concept of db measurements. it would be like me saying the lancer has 2 hp, if i'm trying to say it doesn't have alot of power


fyi, 0 db is the threshold of hearing, while 10 is leaves rustling, 20 is people whispering, and 50 is the average car(of course this varies depending on who you ask and what tables your looking at)

you got a computer in the house? most 80mm fans make between 20-30db

 

if you stand at the back of your car and listen to your stock exhaust/muffler...how loud is that goona be?...hence the point of my posts...the only thing you will hear should be the engine up front but not the exhaust...even at 2-4k rpm... you wikll barely hear it...and with a decible meter...i dont think it will go up to 50db

 

Yes it will, when you rev the engine. I think the point you are trying to make in previous posts is that at idle there will be very little sound. That is true for nearly every single exhaust on the market. In reality, when was the last time someone got a "loud exhaust ticket" when they were standing still (unless the cop was a d*** and gave out an "illegal exhaust" ticket)?

My DC Sports exhaust on my Civic raised the noise level to a whopping 96db, I measured and checked it against the documentation I requested from the company. No wonder I got a ticket for it. As to what urbanknight said, some states have a legal limit, others are subjective to the officer listening to your exhaust. Here in NY, it's up to each township, and it's completely subjective. I switched to an Apexi WS exhaust, which ended being an awesome exhaust, and lowered the levels back down to a tolerable amount. Too bad they don't have it available for the Lancer so everyone here could enjoy it.

Any straight through muffler design (Apexi N1 and all those other ricer "BOMB" style mufflers) will increase noise levels significantly compared to stock. My RMR axle back increases the volume a moderate amount.

 

i dunno how quiet your exhaust is, but my completely stock lancer idle is probably around 20-30db(just a shot in the dark) and that is straight out of the muffler

i agree with you that stock it is pretty quiet, just not within the range of 2-7db as you said

 

I think we got the point, he was exaggerating to make an illustration. db is a strange scale with an exponential factor, so unless we have a db meter, we really don't know (as GreenPsycho said, a shot in the dark).

Point of the discussion... stock is quiet, aftermarket is anything from not so quiet to down right loud.

 

thanks for the help guys

 

well i once saw this chart from import tuner and greddy gave the most horsepower i think and stayed on the db limits.

 

I actually saw the same add. The only thing is its for a WRX. Since that is a completely different car Im not sure how much thought to give it.
