I'm guessing you're talking about the HKS? What don't you like about it?

I bought and put the HKS exhaust on my IS250. BC, the sound of the exhaust was a bit louder than I expected, I took it off and purchased a new tanabe exhaust, but did not put it on the car yet. I see that many people who went for HKS Hi-Power exhaust, was not satisfied because of its loud sound at the first time, but they liked it after a few hundred miles applied on it (break-in period). If I keep the HKS exhaust on my car for several hundred miles, would it eventually be quieter than the first time? I am already trying to sell the HKS exhaust, and put the tanabe exhaust on, but if it will be quieter than the first time for sure, I am willing to keep it.

I have a feeling that after a few hundred miles people just get used to the noise.

That is definitely not the case. I went back and listened to the video I posted with good speakers, and the noises I heard in that video are not ocurring anymore.

Huh?! I haven't heard of this. Are you sure that you aren't thinking of the OEM Lexus exhaust that is designed and manufactured by HKS? It is not a "Hi Power" series at all.

Agree.. I don't think there is another version of HKS Hi-Power.

So, you guys think that it really gets quieter or our ears get used to the exhaust sound?

I just answered this question a few posts up, but does it really matter? People that have the HKS exhaust complain about the volume at first, then they think it gets quieter (In my case, I think it REALLY DID get quieter), and they are happy with it. Why does it matter? One thing I still plan to do is buy a pair of HKS silencer inserts that I can pop in whenever I've got my grandmother in the car with me (or whoever) that might be irritated by the slightest sound.

/ start rant/ my bad, i guess they sell everything in IA/TX and i am retarded...

they do make it, i have seen it, touched it... and if they make it, you can buy it..

ohh ohh ohh wait. HKS says i am right.. http://www.hksusa.com/products/more.asp?id=715

sorry to be so iritated but a simple search was all that was needed to see the "silent" series... /end rant/

Calm down slick! The link you posted is a link to the exhaust that I currently own, and there isn't a "silent" version listed for the 2IS. However, you can purchase the 115 mm HKS silencers, and install them in the HKS mufflers, but there will be a significant power loss. In my experience, the power loss is WAY more significant that just keeping the stock exhuast.

This might be a stupid question, but (assuming it's even possible) would putting smaller tips on the HKS cause any change in sound or any power loss? I don't know if that size is just for show, or if it really uses all that width.

If it wasn't for those damn tips, I think I'd be sold on the HKS.

The whole point of getting the HKS Hi-Power over the Tanabe exhaust is to have those large tips on top of the growling noise, no?

The noise I like, the tips I don't.

I don't like the tips either. I thought about trying to replace the tips, but I can't figure out how it could be done.
