I have cherrybomb pro on 07 5.4 sc. I want it a little louder. Right now the muffler shop extended the pipe about 1 foot then turned it down about 6 inches w/slash cut. If I did a turndown just after the muffler would it be a little louder. It sound deep, I just don't have much roar when you step on it. I really think it's louder at idel. I know I can put Hi-flows, but building a house and funds are tied up.
