Ok guys I'm going to do the gotts mod. I read how simple it is and everything so why not? I'm thinking about also removing the silencer...does it sound good or like ****? And also is it effective? I'm also going to get a k&n filter for it, and was wondering if I should use the stock air box? I've seen some people with no air box with the cai? Does this work for the gotts? Any tips from oeople who have done this would be great.
Thanks!

Btw I have a 2003 scab 4.6 if it matters

 

On the gotts just put the new filter in and put your 3in pipe going into the fender then you'll be good. What we did on my friends truck and it works great
