Vibrant Performance makes a direct bolt on muffler for 9thgens.
I have one now. It's a dual tip muffler and looks good. It sounds nice as well. Not very loud at low rpms - comparable to a nice prr.....but it roars at wot. I can vouche 110% for the vibrant. I'm pleased with it and it still looks new after one year of use and abuse here in canada with all the snow and salt.
Plus all said and done, it a bit cheaper than the trd/borla brand
I picked mine up for about $300.
Here it is after one year of use. (I took it off the car, because i lowered it on s-techs - over the summer and the tips would be scraping the snow/ice and such...and i didn't want that. I'll be putting it back in the spring)
Here it is on my car
I know its a bad pic. but its all i have of the exhaust..lol
cheers, and good luck on your hunt.
