If you have one I want to ask if you can notice a difference?

I've just installed one on my motorcycle yesterday and I think I'm noticing the difference. I'm just not sure if the difference is in my mind or not (sort of the power of suggestion thing).

 

Funny you should ask...Today I just Re-installed mine on my SHO, I think I noticed a difference, the car seems to pull a little harder when at lower RPMs in fourth gear...and pulls harder from a stand still too...Im pretty sure I feel the difference...Im just worried about the oil, I hope I didnt over oil the filter....

 

Same thing I'm experiencing with my bike. So I guess it's not just me.

 

Didn't notice too much of a sound difference with mine. I think it accelerates a bit smoother, but I dropped it in nearly right after I bought it, so I don't remember how it was before.

Tell you what I do notice, is the 1 or 2 extra mpg I get with it.

 

i only ever notice a real small difference
