I'm on the stock down pipe until Sunday. I will be putting on the invidia catted. It won't change the sound hardly at all. I've been in a couple 11 sedans with the q300 and it sounded the same to me. I did a camping trip with the car loaded down roof rack and all, had to have the seats down for almost 5 hrs straight. Did drone just a tad. I very rarely have the seats down though. I have done it just for the sound too though, lol makes me feel faster!
