I have a 4.6 1997 f150 and wanted to know what you guys thought to get a rumble out of it. It has a leak now do I just figured I will redo the whole thing. I was thinking pypes catalytic converters where the stock ones go. Then cherry bomb muffler to a y pipe then to big tips

 

Get a Dynomax Bullet instead of a Cherrybomb. Then Y pipe with your exit of choice. Don't touch the cats until because you'd be surprised with how loud that set up is. if you're still not satisfied, then take out the rear cats and save yourself the hassle of buying and welding in new cats.
