Q: At what rpm do you start to "hear" your exhaust?

I'm contemplating purchasing this muffler, and have read here that under normal conditions, it's nearly silent. I also understand that under WOT and 5-6K rpm it becomes a beast ;]

I was curious as to what RPM range gave you a: 1. murmur, 2. burble, and 3 roar.

I would prefer the idle to be nearly silent, and as little drone as possible, which is why I'm looking at the HKS, but still want to go "vroom-vroom" when I get it above 4K.

Thanks in advance!!!

 

you can definitely hear it at lower RPM, i notice it at 2k but it picks up quite a bit over 4k

 

when i had mine on, it was noticeable at any rpm including idle. that was before the y pipe and hfcs at which point it became too loud. i thought it sounded great at wot but the low rpms with an auto was a tad annoying in my opinion..

 

Thanks for the input, guys! The information is incredibly helpful.

So I guess the million dollar question is:

Does it drone at 2.5K RPM on the freeway, 70-75mph cruise?

You mention you could hear it at 2K rpm....which would leave me to believe that it would drone at 2.5K =/ ?

Many Thanks.

 

Which Y pipes are you running? And did the y pipe or hfc's make more noise?

Also, if you don't mind me asking, what setup are you running now?

Sorry for being so inquisitive; I merely don't want to make a purchase only to suffer buyer's remorse =)

I have a Tanabe y pipe since it has smaller inlet dimensions the 3" inlet y pipes. The hfcs are berk. I had the y pipe on with the hks and it sounded good. A little annoying around 70mph cruising and going up hills at a low rpm. After the hfcs, it got too loud. I would have to say the hfcs would cause a higher effect on the tone and volume of the exhaust than the y pipe.

Right now its just the hfcs and y pipe on with everything else stock. I still have the hks sitting in the garage. I could stand a little more sound soI have considered using a round magnaflow resonator to replace the one in the stock midpipe one as a few members have done but no definite plans of yet. I will mention that I am probably more sensitive to the noise than others. In my previous VQ30, the entire exhaust was aftermarket except the rear section, which worked great for me.
