Your exhaust sounds great! It has that nice low guttural aggressive tone.

How did you accomplish this? I'm running the Eisenmann Race Quads and am not sounding as nice as yours. Did you replace the mid section, of your exhaust system, with a straight pipe too?

As a side note, I understand that some exhaust enhancements can actually inhibit performance when done without the use of a tune. For example, using a downpipe without a tune will cause performance to worsen.

If I run Eisenmann Race Quads and replace the mid section of the exhaust system with a straight pipe, without a tune, will performance suffer?
