What kind of power gains will I get on my mojave with a White Bros e-series s-bend exhaust, 13 tooth front sprocket, and a K&N power kit? also is this pipe loud?

 

That will pep the wake the old moajve right up!!! And as far as the pipe goes, no the WB-Sbend is not very loud at all.Hopw it helps!!And anouth pipe i would sugest it the NEW Pro-circt R4 , this is a really nice pipe and has a nice deep sound!!and U could also go with the IDS2 made by supertrapp

 

The WB s-bend sounds great but is quite loud. I have one on mine.

 

does it give a good power gain over stock?

 

Yes not to bad!!!But if I were u I would look in to the Pro-circt T-4 , it looks like a really nice pipe and sond like it has lots of powere gain!!
