hello talk about this change:

 

Uppppppppp .

 

I'd go with the Fister Sport Muffler modification if I were you. I just had mine done, and I love it.

 

What changes were made with small tube or large?

 

The left image in your original post is the Fister Sport Exhaust. I had mine ceramic coated, just like the ones in that image.

 

These? Did you hear differences in performance?

 

I'm not sure what you mean...

I can hear a difference in the sound of the engine, but I'm not sure I can "hear a difference" in performance. I bought them strictly for sound improvement, not for performance.

They are noticably louder than a stock OEM exhaust, but not too loud. If you are looking for something loud, I suggest you try an aftermarket system like Fabspeed.

 

Ok I understood that only improves the sound. I do not know whether to merge the change into the tube and the output, or make a curve and connected to the outlet pipe.

 

I'm sure it will sound good either way. I'm happy with mine, which is the partial muffler bypass welded between the inlet and outlet pipes.

Good luck with your choice.

 

I made the change with the addition of a third pipe, the sound and 'deeper and fuller. Very good, maybe add 'even the tube that connects the inlet and outlet do you think?

 

yeah do it should sound awesome!
