So I'm currently looking to purchase an Invidia, or Megan mid pipe to custom on my 07 IS250 AWD this summer, but i cannot wait that long, i want my exhaust to be louder now.
I currently have the Lexus HKS axle back exhaust, and I thinking about doing something to my stock mid pipe for the time being.
I am looking at 2 options
1. Delete the resonater
or
2. Delete the secondary cats.

If you guys could provide me with some details, and your personal opinions that would be great!
Im looking for a deep throaty sound i guess, just something more aggressive if you know what i mean.

My main concern is drone inside the cabin, as my car is a daily driver i want to keep that to a minimum.
Thanks everyone! Much appreciated!

Invidia midpipe for loudness with the cons of more drone and raspy. Cheaper than Megan.

Megan midpipe for more aggressive & deep throaty sound. Little quieter than Invidia but less drone and less raspy.

I would go with Megan. Someone has Megan + F Sport and it sounds smexy.

What if I went the cheapest route and just deleted the resonator or secondary cats?

^^ if you do that route, it will definitely be louder. How loud? I do not know on the HKS but on the stock mufflers, it definetly had some drone and rasp.

I kept my mid section for two reasons. One is that 300 bucks for more noise didn't make much sense to me. The second is I deleteded my rear resonator and it drones in the rear of the car. I'm sure you can go with a smaller inline resonator but what's the point of that? The "secondary cats" to my knowledge are just small resonators. Honestly any route you go it's going to drone pretty bad.

I've herd the HKS kit and they seem to be a little quiet. Why not sell it and just get a little louder kit? Keep the resonators and not worry about any drone?

I am on the same boat, I have F sport on my IS350 but its not loud enough, Megan midpipe doesn't delete your secondary cats and the piping is the same size so what are we paying $499 for? a Megan resonator?
