I've searched but found no definitive answer to what I'm looking for. I have:

2010 IS350
Tsudo Axle-back
JoeZ Intake
All else stock.

I like the sound I have now but I'd like to increase exhaust noise, go deeper if possible, but not increase the cabin drone. Rasp is not wanted. Not one bit. The closest I saw to what I am looking for was this:

PERFECT IS250 AWD Exhaust Setup - ZERO Drone, Deep Tone
After struggling for weeks tinkering with my exhaust trying to produce a no drone deep true V6 sound I finally hit the mark.
Stage 1: F-Sport Axle Back (By itself = too much drone, too high pitched for the cabin of a luxury car DD)
Stage 2: Removed secondary cats - Replaced them with Vibrant 12" Bottle Resonators (More flow and more of a rifling V6 sound but still a lot of drone between 2500-3000)
Stage 3: Game changer - Replaced the single stock muffler resonator with a straight through 14" long 6" across Magnaflow muffler (3 mufflers in total you say? YES!)
The result is the way luxury sport sedan should sound. If you have a girlfriend, wife, kids or are just over the high pitched annoying exhaust bit. Do what I have done. Don't think about it, just do it.

I'm considering trying the above except that I think I'll skip stage two's resonators and just delete the cats.

Thanks in advance.

 

Love the tsudo. Resonated midpipe would help prevent rasp while increasing noise level. Unsure of drone though. Maybe a custom X pipe ?

 

Any feedback for the is200t F. Im looking into exhaust “axel back” to start with as well. Im trying to find people with the setup using either Magnaflow Street series 15227, Invidia Q300, or Flowmaster . Right now I have a Injen intake and F-Sport springs 1in drop.

I was leaning to the axel back. Since its just the back and simple to put on. Just wanting to see what others have done for sound. I like it to sound throaty and low smooth tone on start up and only really here the roar with accelerating. Right now I have the Injen intake. Which I like. As you can really hear the spay form the turbo i.e. Jet sounding lol .

 

I had a tanabe axelback, had drone around 3k RPM. Just put a megan midpipe on and the drone is gone.

Megan midpipe is the way to go.

 

I'm going to go with the Megan midpipe but I'm spending my play money on other hobbies right now so it's looking like a winter project.
