Hi all,

I modified my exhaust by removing the resonators and the sound turned out really great? See link...https://www.clublexus.com/forums/sc-...s-removed.html
I saw other memeber modified their stock air box, so I did mine with K&N air filter. After both resonators and modified stock air box, the car is a lot more responsive and has a great sound. Enjoy.

13 HP, how dis you calculate it? Did you put your car in a dynamometer?

Great job - that was me with the same airbox mod also with the K&N. I was just listening to your exhaust over the weekend - sounds great.

Mandyfig - I did get it on the dyno and checked the difference and more air added between 4-6 HP. Doesn't seem like much but I am pending installing the PPE headers, and am considering cutouts for the track when I can use the extra HP. So the package of those mods (intake, headers, exhaust or cutouts) should make for more power noticable on the track.

Thanks for the writeup. Your intake mod inspired me to do the same.
