Tuning for that can probably be pretty annoying.

if u anyone used this direct exhaust cutout in malaysia, they might set fire on the petrol station. cause there are a lot of diesel car here, and normally there are a lot of fuel left on the floor waiting for cleanup.
I have an AT6spd rx8 with an automatic exhuast cutout. I have it right before the CAT. It's loud to the people around you with their windows down. Inside the car though, it sounds like a regular exhaust.
Can you feel the difference? I put it against a rsx S and is250. I ran them with closed stock system and open exhaust. The difference was huge for me. I was neck to neck with them on stock form. But when i opened the cutout at 80mph, I started pulling on them easily.
remember, this is an AT6spd rx8 that everyone is complaining about. I'll try to line it up against a MT and post vid.
I hope this helps.
