So my 2007 IS350 has the HKS HiPower axleback exhaust on it and it make a good sound but only when I'm cruising at certain revs in certain gears. My friend who has an IS-F also says my exhaust sounds good but he always says that I need new headers. So my question to whomever reads this is what should I get that will sound good with what I have and from where?

PPE headers are the only option besides the ebay ones. Do u have midpipes? Changing your midpipes might get you the sound you want.

Get PPE headers, keep the stock midpipe, and keep the HKS exhaust.

Is there a quieter midpipe? I have the nvidia with F-sport and it is obnoxiously loud? I want to have a full catback + Headers. Can't imagine how loud that would be

There is a Megan Midpipe but it is kind of rare to find.

So the PPE headers will give me good idle and revving sounds with my current setup?

That's with ppe headers and hipower exhaust
