"Y pipe / Cat Eliminator" question - July 26, 2007, 02:33 PM

While I was browsing the internet the other day reading up on suspension stuff (my #1 priority) I came across a good deal on a mid muffler eliminator and thought I'd pick it up.

I was wondering if anybody has had any experience using something like this. My thinking was that eliminating all that goes on in the catalytic converter would have some benefit for the engine (and a few pounds lighter that I wouldn't notice). My thinking was that this would sort of be like a poor mans full exhaust since I would still be running the stock slip-on. Obviously any modifications like this would be most beneficial with a Power Commander/ECU reprogramming. Also with the installation for the mid pipe I could possible removed or disable to “exup” valve (I'm not sure if this is R6 specific). Especially with my growing interest in doing track days I'd hate to spend money on a nice exhaust had have it get damaged when I inevitably go down.

I was just wondering what everybody’s .02 and experience on this mid muffler eliminator was. Thanks in advance!

Unless you're racing full time you want to keep the EXUP valve. That's what makes the midrange power which is mainly what you use on the street.
