Yes I do let me see if I can get them on here..and they really dont pop alot, only sometimes. But they dont pop near as much as flowmasters or straights.

I swapped my stock muffler for a magnaflow myself. Here is my thread on that with a few pics that might help if you decide to do it yourself. https://www.f150online.com/forums/ex...than-80-a.html

I just put on a SI/DO Flowmaster 40 series on my 5.4 and it sounds downright viscious....It seems a lot punchier and torquier as well. Could not be happier.
