I just installed a two brothers slip on with a mid pipe included .the cat came off with the stock pipe and the o2 fits into the new,mid pipe. Pipe sounds awsome but now there is a really strong exhaust smell that tends to saturate my clothes. Seems to be running real rich. Any ideas? Power comander maybe?

 

Let's start you you own thread. You won't get much help from a 7 year old conversation.

Is the pipe new? It could be the new pipe burning off packing oils and such. Are you sure it's running rich?
Retrace your steps to make sure things were plugged back in correctly.

 

I agree with Demon. I just installed a 2 Bros M2 3 days ago and there was a slight smell on the first day. Hardly noticeable but I could tell. You could go either power commander or 2 bros actually offers a juice box which has pre-programmed maps with oem connections plug and play for around $200. Something to consider.

 

Thanks guys. Any chance I should pay to have the bike on a dyno before getting a juicebox. The smell is still really bad after a number a tanks run through.
Smells like a sled!! Lol

 

Something is wrong then. Installing a slip on with the 02 sensor still installed should not make the a/f ratio change at all. OR you just aren't used to a non cat convertor exhaust.
