After Cat X pipe?
Right now I have SLP Loudmouth axle backs on my 14 GT. I want to do more with the exhaust but because the hassle of removing the cats I'd rather leave them on since it is my DD. Is there a noticeable note difference between the stock H pipe and say, a BBK after cat X? It seems like a reasonable mod if it's worth it. Then, I could add BBK headers too. Yeah?
