The stock exhaust flows pretty well all the way out. I have the IPF S/C and haven't changed a thing.
Sure, you can add Solo high flow cats, but I'm skeptical of their long-term durability.
Any axle back exhaust is for sound and to shed weight. No one has shown me any gains other than that.
Just my opinion.
