Ok i have a 2001 300ex. i want to get the Wb promeg pipe ofr it. is there anything else i need with the pipe?
i might also put a k&n power kit in. which is just new jets correct? if i do get the power kit is there anything else worth buing with it or not.
please help me out here guys

 

I have the e-series pipe for my 300ex and a K&N filter. It adds good horsepower and some top end however the low grunt is a little bit louder than stock. If you can get away with the noise go for it. I didn not have to re-jet, I just added the new pipe and filter and I was off...... you will climb hills a lot better with the pipe on...

 

Maybe some ear plugs......LOL
