I heard how the a'pexi N1 dual sounds on a 240sx and it sounds great!, but I really cant hear how loud they are over the computer speakers. I have also noticed that I cant find out anywhere how much noise theses exhausts make (in decibels (DB) at least). Even A'pexi does not say how much noise they make; they dont even have an email address. Does anyone here have an a'pexi N1 dual exhaust on the s13 or s14 240sx SR20 OR KA24 engine?

If yes, then I have a few questions for you.

1. Do you know how many decibels (DB) of noise it produces? 2. How loud is it to you?3. Would you reccomend it for daily driving?4. Have you been botherd by any police/authorities yet?5. Do you have the 90mm silencers? if yes, how effective are they to you?

-Thank you __________________

240sx2nr95 (Dan) has them.

Silencers suck though. Waste of $. If it's too loud, it's poorly designed.

I have the duals, and I'm sorta undecided on them. NA they are extremely loud... they tend to drone around 3k RPM which is right where I usually am on the highway... In my opinion they are not really suited for daily driving on a NA car, the drone got annoying and it makes it hard to hear your music.

With the turbo they seemed to have quieted a LITTLE, it probably doesnt help that I have a test pipe but still: it is a fairly loud exhaust. I dont know about dB levels specifically but I havn't been bothered by any police as of yet and Ive had them for over a year.

I think if I had to start over I might try a different exhaust, but these arent so bad that I would spend the money to change to something else right now.

Overall rating of EH.

Thanks for the info! Hmmm... your car is a hatch. Wouldnt the noise be a bit louder in fastback 240s?

Even though you said a turbocharger makes it a LITTLE more quiet, does it still dorne at 3k rpm with a turbo?
