Once I've got some money together I want to do some tuning on my bike. I've got a few things in mind such as exhaust, jet kit, high flow filter (undecided on brand). My question is about the difference between a full exhaust and just buying the bolt-on muffler. Is there really a difference in air flow between a stock pipe and aftermarket? I just assumed that would all be controlled by the baffles in the muffler itself.

Basically, I just want to know the difference and am wondering if it's worth paying double the price for a full instead of just a bolt-on. And maybe recommendations on an exhaust would be nice, too. Oh, it's a 99 zx-6r. I've told you all before in my carb problem threads. Basically I want something louder than the stock. I'm guessing pretty much any aftermarket would accomplish this, but I want it to sound tough and also give adequate airflow for the jet kit to run at it's optimum. Assume that I'm extremely new to this, but I have been doing some reading. No actual real-world experience on these mods that I intend to do, though.

Thanks for any advice you all can offer.

 

The slip on will give you more on the bottom end and the full exhaust will give you more on the top end. So I hear.

 

I have a ZX10R w/full akro evo exhaust. With a few mods. It comes alive @8000rpm. My stock 10 has more on the bottom end. My katana has a slip on, a little more power all over, way better sounding.
