I installed a ASURA exhaust on my 03 about a month ago, the reviews and posts were kinda miss leading by saying it was a pretty quiet exhaust, lol. Anyways, I got a good deal on it off craigslist for $400 in mint condition, looks very good after polishing the grime off. I love the Oval tips but had a few fitment issues, had to beat in the passenger side tunnel with a ball pin hammer a bit, but finally got it rattle free. sounds amazing when the top is down!

I also put a Invidia 70MM test pipe with it. Now, my question is; how can I reduce the drone? Am I stuck with it, or would putting the cat back on reduce it enough to matter? I'm sure I wouldn't notice a performance difference, would I?

I daily my S2k, and it gets pretty bad unless I'm in 6th gear all the time, lol.

If this is one of the quietest exhausts I can't imagine a Invidia N1!!

 

You can try adding in resonators if theres room, but your only options other than that are silencers if your exhaust allows you to run them.

I have a skunk2. It's droney and loud but I've adjusted to it and driven it enough to know what rpm ranges are worse at certain speeds.

 

i've heard cats have more drone. test pipes are louder, but they don't drone as much

 

It's got one resonator already I believe, and no they don't make silencers that I know of.

 

Is this a pic of your exhaust?

If you have a straight pipe like whats in the pic you could try one of these race muffler.
It should not change the tone at all but it should turn the volume down 5 or 6 db's and with nothing to burn out it will sound the same on year 2 as it did on day one. It might even help with the drone.

Agree with the others, a test pipe will be the least drone option as far as piping. Adding another resonator might help but i dont know how much you want to invest. I have a HKS 75mm and I use a silencer to kill some of the noise and all the drone when I daily drive it and remove it when I want to have fun. Oval tip might make a silencer hard to get in but you might want to try figuring it out. GL
