I put a micro tuner, took the cat out and drilled the stock baffle sounds good not loud but good no ringing in the ear's after a long ride. Think it will be left that way as I don't like real loud pipe's. Has a good sound when you get on it and at idle.

 

I recently replaced my stock cat header pipe with another catless stock header pipe I got on E-Bay! sounds awesome with my SE Slipons!

 

For those of you wondering if you need a tuner by removing the cat only, my personal conversation with Fuel-Moto is you do not.

 

No one is questioning whether or not one is "needed". Your bike will run better with a tuner, whether your converter is in place or not.

 

Link to this product? Couldnt see it, sounds interesting

 

Is this a confirmed improvement? I was under the impression header pipes might as well stick to stock(modified), no advantage in going aftermarket

They will modify your own pipes, or if you are in a hurry, will sell you a set already done, and they buy back your originals if they are in resellable condition.

Perhaps no item in the history of the world has gotten as much attention as exhaust modifications for Harleys : >)

 

My '09 had stock non-cat header and '11 SG mufflers when I got it. It was pretty quite but louder than stock. I actually really liked it. When I went 103 put some Fatshotz on. They are louder but not bad. Put Fulsac header on, sound didn't really change but picked up power. I do actually think decating the stock header is a waste if ya are looking for performance. It will give ya more noise and less heat in the collector but it is still a poor design for performance and the cat does not really restrict flow on a stage 1 bike.

 

I really believed the '09 non cat 2-1-2 was a really good design until I put a Fullsac header on... I was wrong.
