I have stainless power headers with a 3 inch borla atak catback. I love it, quiet when i want it to be and loud when you get on it. I had corsa extreme before and was not a fan of the tone after in header install.
My first setup was stainless power catted long tubes and corsa extreme catback. Still had zero drone with the longtubes but it lost all tone that the catback had. Honestly after 3k it was just rasp. I switched to the borla atak catback and absolutely love it. It is alot deeper but will say it is...
