I took off my pro pipe didnt like the looks or sound personally and wen to the big radius 2into2 and i have noticed a few times that when i hit higher rpms it cuts out a little bit. Do you think that with the switch i might be running a little to lean and need a bigger jet? or maybe just go with a cooler spark plug??? any experts let me hear it

 

You could be running lean. The Pro Pipe would have more backpressure than the Big Radious 2-2 I would think.

 

its a o4 dyna
