Morning everyone,

Was wondering if anyone has done a dyno with the 2013 Lexus GS 350 RWD stock. Would like to know the stock wheel horsepower to see how much I'm gaining after installing custom glass pack mufflers and HPS Short ram air intake.

I've seen this thread but it's AWD so /:

 

I recommend that you do a baseline before installing the parts. Dyno figures vary from car to car.

 

Yes, K&N did one. I agree with 13gs350, it varies by car & conditions so the only way to know is to do your car pre/post in similar conditions.

Problem is I already installed custom mufflers without doing dyno before that /:

 

Do you like your results in real-world driving? If so, why bother with the technical mumbo jumbo?

HPS claims dyno-proven results of +14.5whp, why question the manufacturer?

Perhaps more importantly, how does the car sound?

 

to the OP. Your other option is to see what it does in the 1/4 mile and compare that figure to various publications on a stock GS350...Motor Trend, Car & Driver, etc. See if you can best those times.

 

Yeah i guess you have a point there.

Just received it today so I'm looking forward to installing it

 

Never thought about this. Thanks for suggesting!
