100% noticeable, but could be because the car was lot louder too haha.

Made the car a lot more fun and enjoyable. Keep the stock parts for when you want to revert back / sell the car.

loud=faster?

 

Some beautiful work done on this LC, sound clips at the end.

 

Why!?

 

Exhaust mods are just like cool air intake mods. You get as much HP gain as the marketing agent is allowed to advertise.....

 

Curious, why the axle change?

 

I'm assuming Lou meant axleback.

 

^^^^^No, I did not

That's what I get for typing when tired, haha.

 

He's talking about the axle ratio or gear ratio. A shorter gear ratio (higher number) would allow the car to accelerate quicker with the same amount of power. There a whole thread on swapping the LC500h differential that is stickied here in the forum that explains.

 

From what I've seen and read, there seems to be scant few options for improving "performance" on this car. Performance defined as power (hp, torque, or both) or acceleration. Not cornering, etc.

Until someone cracks the ECU coding and fuel maps, the diff. swap out looks like a reasonably priced upgrade with measurable improvements in 0-60 times albeit at the cost of lower top speed. I don't believe for a second that the replacement exhaust that Josh from Meraki mentioned provides any meaningful performance improvements. Same bore, same routing, just prettier and louder. Show me the dyno runs or 0-60 comparisons and maybe I'll believe it.

Can't wait for something that gets this car to sub 4 seconds on a 0-60 run though. 😁

 

Need to work on getting under 5!

 

ECU has been cracked. Look up VF tuner software. Tuned by Loi or Reflash RD is already tuning our cars.

 

Hey "IS_250"............for THIS car? Or for the IS 250 (based on your login name)? All I see on their list is a tune for the Lexus IS 250 and 350. Haven't heard even one person say there is an aftermarket ECU tune for our cars. Anyone know otherwise?

So, going with a big NO for ECU tunes on our cars until proven wrong (which I'd like to be).

 

^^^^

Loi does it, up to MY2021.
