Hey guys, just recently got an '18 350 F Sport, and the stock exhaust leaves much to be desired. I've been reading exhaust threads since day one, and listening to YouTube videos as well. Unfortunately, I'm just as confused as when I started. I know you've seen a million of these threads, so I'll make this easy for you...

Given these parameters, what would your recommendation be?

1. Axle-back only.
2. More volume would be good, but not boy-racer loud, and as little drone as possible.
3. Deep, warm tone, not bright and raspy.
4. Price is not a consideration.
5. Lexus quality or better.
6. Power gains not a consideration at all.

Thank you in advance for any advice!

Drone exists, but I'd say its only bad at hwy speeds. If you're by yourself, you'll prolly wont mind it. You can compensate by downshifting into 6th to get out of the drone. Also, ZERO rasp. I personally dislike rasp as well.

 

Made these videos. Would like to emphasize the use of headphones. My recording skills suck and couldnt capture the true depth of the exhaust. Hopefully it comes out well.

 

Magnaflow!

 

Replied to your PM!

Go F-Sport Axle-back if they will fit your 2018. Probably more of the quiet exhausts but little to no drone. Has a light deep tone with no rasp.

 

This is what I've been hearing. It's really coming down to the JoeZ, F-Sport, or Tanabe Touring. Just have to figure out which now.

 

you should watch videos from within the cabin. while you're driving, it's not going to sound like the clips where somebody's got a camera staring at the exhausts.

 

Personally i'm driving a 3IS 2014 RWD F Sport

Originally the car had a invidia axle back with quad tips welded on, i replaced it with a RC350 Tanabe Medallion because i was told it was quieter (93db?) than the invidia axle back.

Personally I believe the invidia was quieter at lower rpms, with the Tanabe, after about 1.5k to 2.2k the inside cabin noise is very loud compared to the invidia.

Outside of the car it isn't too bad, it's just in the cabin it's becoming almost unbearable at every light that it's so loud in-cabin. I was hoping more for a quieter low rpm, and loud when i open her up, but its only quiet mostly when coasting.

May switch back to the invidia, after getting better quad tips welded on. the RC350 Tanabe quad tips are perfect for the 2017+ diffuser. The sound volume may lead me to get rid of it though. i will test run the invidia again here shortly, and i will attempt to make a in-cabin sound video for you. outside-car as well if i can get someone to record.

hope that helps a little.

 

Man, that sucks, I was hoping for better reviews. Sounds great outside the car.

 

Strange. I got my Tanabe Medallion because I wanted a bit more sound than stock --didn't want anything too loud. At idle, you do not hear it at all in cabin or outside. I do agree that at about 1.5k-2.3k rpm, during freeway driving, the drone is there. After about 5.5k rpm, you hear engine, and no exhaust note in cabin.

 

Which is the worst design possible, seeing as how most Interstates are 70 mph, and most people are going between 75 & 79 (1900 to 2300 rpm)...right where the drone rpm is.

 

Agree, not great there, but I'm not too annoyed with it... yet. The sound does change, I've only had it for 2 weeks or so.

 

 

Just like the car itself, there just isn't any right answer here. I'm back to thinking OEM F-Sport is the way to go. Probably too quiet for most, but it's better than droning like crazy every time I have to take a trip.
