This is exactly the video I’ve been looking for. So deleting both Mufflers and resonators sounds just like Borla but louder and more crackling. Interesting.

Maybe, a few at the most, but really the problem in RCF is the mid-pipe diameter which is barely over 1.5 inches and the pipe routing is very restrictive with a nasty 90 degree bend. It is a big, high strung V8 that needs to flow a lot and Lexus put restrictive exhaust to pass Euro emissions etc.

it’ll add some hp and tq. It’s mostly sound. Mufflers are restrictions as well. They weigh a lot too. Inspection wise, you can still pass. Mufflers reduce sound, not emissions.

I will throw Invidia in the mix as well. This is the setup I am going for. I will be the first to remove resonator off an Invidia full catback as it has never been done

You aren't going to add a Borla to your F are you Rolla?

I know my Borla will wake up everybody and everything if I start it at 530am in a crowded residential area. Definitely NOT GOOD. Worse if you are in a confined area like a garage or underground parking structure.
Luckily for me I'm in an open area and there are lots and lots of other vehicles such as pickup trucks/Chargers/Camaros with glass packs which are way louder than mine.

Wondering the same. In the one shot when he pulls away it sounds almost as loud as Borla. I don't love the blue tips....actually at all...but maybe that can be addressed.
